Detailed Description

template<typename Type, int Channels = 1>
class QVImage< Type, Channels >

Image representation class for the QVision.

QVImage class extends QVGenericImage, and wraps image data in a simple and lightweight structure, easy to use. It is a template class, as you can see in the header of the class:

template <typename Type, int Channels = 1> class QVImage: public QVGenericImage 
        {
        [...]
        }
parametrized with the data type of the pixels in the image, and the number of channels that it contains.

Image Types

Image bit-depth.

When creating an image, it's bit-depth is specified with the first template argument Type.

Virtually, you can specify pixel types of any kind, but QVision has defined functionality to process pixels of the following types:

C++ type QVision type IPP type Bit depth
unsigned char uChar Ipp8u 8
unsigned short uShort Ipp16u 16
unsigned int uInt Ipp32u 32
signed char sChar Ipp8s 8
signed short sShort Ipp16s 16
signed int sInt Ipp32s 32
typedef float sFloat Ipp32f 32
typedef double sDouble Ipp64f 64

In practice, most of the functions will work with images of type uChar, sShort, and sFloat.

Number of channels in an image.

Each image stores a vector of values of type indicated in the first parameter of the template for each pixel, of size indicated in the second parameter of the template. The latter is called Channel number or simply Channels, and it indicates the number of channels in which the image stores the data.

For example, the following code line creates images of 8 bit-depth, 16 bit-depth, and 32 bit-depth, of one and three channels:

QVImage<uChar, 1> image8uC1;
QVImage<sShort, 1> image16sC1;
QVImage<sInt, 1> image32sC1;

QVImage<uChar, 3> image8uC3;
QVImage<sShort, 3> image16sC3;
QVImage<sInt, 3> image32sC3;

You can ommit the number of channels, if you want to create a one channel image, because that will be the default value for that template parameter. Thus the first three code lines of the previous example can be written like this:

QVImage<uChar> image8uC1;
QVImage<sShort> image16sC1;
QVImage<sInt> image32sC1;

with identic results.

As in the case of the Type parameter, this parameter can be assigned any arbitrary positive integer value, but generally there wouldn't be functionality to work with images with a channel number different of one or three channels.

Conversion between image types.

When using the constructor and the assign operator with a source image different in type or channel number to the created or destination image respectively, QVision authomatically performs a conversion. Conversion generally calls to the proper ippConvert function, so a review to Conversion between image types. function is recommended for futher learning about this feature of QVImage objects.

Pixel access.

There are three ways of accessing pixel values in an image.

The first one is using operator (). It is the least efficient access method in execution time performance, but the easiest one to use, and the safest. This operator is overloaded for the QVImage class to allow reading and writting pixel values over image objects.

It is slow because it performs some sanity checks, for example to ensure you don't read pixels outside the image area. An usage example follows:

QVImage<uChar> imageCharBis = imageChar;
[...]
// This line assigns the value 0 to pixel (10,10) in the image imageChar:
imageCharBis(10,10) = 0;
// And this line reads value of pixel (11,11) of the image imageChar in the variable value:
uChar value = imageCharBis(11,11);

[...]

// The following code shows how to read and write all the pixels from QVImage's of size 100x100:
QVImage<uChar> imageChar1(100,100), imageChar2(100,100);
[...]
for (uInt row = 0; row != imageChar1.getRows(); row++)
        for (uInt col = 0; col != imageChar1.getCols(); col++)
                imageCharData2(col, row) = imageCharData1(col, row);
[...]

The second method for image pixel accessing is working directly with the raw data buffer. It is the fastest and the rawest of the three methods for image pixel access.

You can obtain a pointer to the memory area containing the image data with the functions getWriteData() and getReadData(). The method getStep() returns the row size of an image in memory, and the methods getCols() and getRows() can be used to know the bounds of the memory area of the image.

The following code illustrates the use of these functions for raw image pixel access method:

QVImage<uChar> imageChar1(100,100), imageChar2(100, 100);
[...]
uInt            step1 = imageChar1.getStep(), step2 = imageChar2.getStep();
uChar           *imageCharData1 = imageChar1.getReadData(),
        const   *imageCharData2 = imageChar2.getWriteData();

// The contents of imageChar1 will be copied to the image imageChar2.
for (uInt row = 0; row != imageChar1.getRows(); row++)
        for (uInt col = 0; col != imageChar1.getCols(); col++)
                imageCharData2[row*step2 + col] = imageCharData1[row*step1 + col];
[...]

That code copies the content of image imageChar1 to the image imageChar2.

The last way is using a set of macros provided by the QVision for image pixel accessing. These macros are:

The first two macros, QVIMAGE_INIT_READ and QVIMAGE_INIT_READ are used to initalize macro access for a given image. The following code illustrates their usage:

[...]
QVImage<sFloat, 1> imageFloat(100,100);
QVImage<uChar, 3> imageChar3(100,100);
[...]
QVIMAGE_INIT_READ(sFloat,imageFloat);
QVIMAGE_INIT_WRITE(uChar,imageChar3);
[...]

To access a random pixel located in a previously initialized image, you should use the macro QVIMAGE_PIXEL like this:

[ ... follows from previous example code ...]
for(uInt row = 0; row != imageFloat.getRows(); row++)
        for(uInt col = 0; col != imageFloat.getCols(); col++)
                QVIMAGE_PIXEL(imageChar3, col, row,1) = QVIMAGE_PIXEL(imageFloat, col, row,0);
[...]

Macro QVIMAGE_PIXEL takes always parameters: image name, row, column, and channel number, starting with number 0 for the first channel. In one channel images, only 0 value should be valid for this last parameter.

Macros QVIMAGE_PTR_INIT_READ and QVIMAGE_PTR_INIT_WRITE work like macros QVIMAGE_INIT_READ and QVIMAGE_INIT_WRITE, only that they are given a pointer to the image to be accessed with macro QVIMAGE_PIXEL, not the name of the image itselft. An example of use of these macros follows:

QVImage<sFloat, 1> * ptrImageFloat(100,100);
QVImage<uChar, 3> * ptrImageChar3(100,100);
[...]
QVIMAGE_PTR_INIT_READ(sFloat,ptrImageFloat);
QVIMAGE_PTR_INIT_WRITE(uChar,ptrImageChar3);

// The contents of 1-channel image pointed by ptrImageFloat will be copied to the second channel of
// the 3-channel image pointed by ptrImageChar3.
for(uInt row = 0; row != ptrImageFloat.getRows(); row++)
        for(uInt col = 0; col != ptrImageFloat.getCols(); col++)
                QVIMAGE_PIXEL(ptrImageChar3, col, row,1) = QVIMAGE_PIXEL(ptrImageFloat, col, row,0);
[...]

Use of macro QVIMAGE_PIXEL is the same for both pointer and non-pointer macro types.

Macros QVIMAGE_PIXEL_PTR, QVIMAGE_COL_INCREMENT_PTR, QVIMAGE_ROW_INCREMENT_PTR, QVIMAGE_NEXT_LINE_INCREMENT_PTR may be used to perform a more efficient image access than the random access previously reviewed with macro QVIMAGE_PIXEL.

Like the latter, macros QVIMAGE_INIT_READ or QVIMAGE_INIT_WRITE must be used to initialize the image. Later, a pointer to the starting pixel in the image is obtained with the macro QVIMAGE_PIXEL_PTR, and using the macros QVIMAGE_COL_INCREMENT_PTR and QVIMAGE_ROW_INCREMENT_PTR we can transverse the image from each pixel to another one in a 4-connected neighbourhood.

Using the macro QVIMAGE_NEXT_LINE_INCREMENT_PTR we can obtain the distance from the last pixel of a line, to the location in memory of the first pixel of the following line for sequential accesses through the lines of an image.

The following code ilustrates their usage:

QVImage<sFloat, 1> imageFloat(100,100);
QVImage<uChar, 1> imageChar(100,100);
[...]
QVIMAGE_INIT_READ(sFloat,imageFloat);
QVIMAGE_INIT_WRITE(uChar,imageChar);

const sFloat    *imagePtr = QVIMAGE_PIXEL_PTR(imageFloat, 0, 0, 0);
uChar           *destPtr = QVIMAGE_PIXEL_PTR(imageChar, 0, 0, 0);

// The contents of imageFloat will be copied to image imageChar.
for (int i = 0; i != rows; ++i, imagePtr += QVIMAGE_NEXT_LINE_INCREMENT_PTR(imageFloat), destPtr += QVIMAGE_NEXT_LINE_INCREMENT_PTR(imageChar))
        for (int j = 0; j != cols; ++j, imagePtr += QVIMAGE_COL_INCREMENT_PTR(imageFloat), destPtr += QVIMAGE_COL_INCREMENT_PTR(imageChar))
                                        *destPtr = *imagePtr;
[...]

This kind of access is very common, and using these macros to access the pixels of the image is more efficient than with the QVIMAGE_PIXEL macro.

Regions of interest (or ROI's)

Todo:
Cambiar, repasar. The ROI is a property defined in the class QVGenericImage, so it is inherited by class QVImage. They are relevant for image processing functions from the IPP wrapper functions group. These functions can restrict the area they process to a rectangular region of the image, called the region of interest.
Section UsageROI details about how these functions operate with ROI regions.

Constructor & Destructor Documentation

template<typename Type, int Channels = 1>
QVImage< Type, Channels >::QVImage (  )  [inline]

Default constructor.

Initializes image with a data buffer of size 1x1. Sets anchor to pixel (0,0), and region of interest to a rectangle containing the only pixel of the image.

Definition at line 612 of file qvimage.h.

template<typename Type, int Channels = 1>
QVImage< Type, Channels >::QVImage ( uInt  cols,
uInt  rows,
uInt  step = 0,
const Type *  buffer = NULL 
) [inline]

Dimensions and buffer constructor.

Deprecated:
You shouldn't be able to specify a pointer to a buffer. If you need a image data buffer, create an image, and use it's. Creates an image of dimension cols x rows, and optionally you can define a given step for the image. If buffer points to a region of memory, it will use that region as image data. Step paramameter should be the width of the lines in the data buffer, if the parameter buffer points to a data buffer in memory.
An example of this can be seen in the following code:

                uChar data_buffer[10][12] =     {
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 },
                                                { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 3, 7 }
                                                };
                
                // Creates a QVImage of size 10x10, ROI covering the whole image, and anchor pointing at pixel (0,0).
                // Data buffer of the image will point to matrix data_buffer.
                
                // The final values of each line, those in 11th and 12th columns will not be considered as part of the
                // image. Step is the length of the lines of data_buffer, 12, not the number of columns.
                QVImage<uChar> imageCharBuffer(10,10, 12, data_buffer);

Parameters:
cols number of columns for the image.
rows number of rows for the image.
step defined step for the data buffer of the image. It should always be greater than the number of columns.
buffer pointer to a memory zone where image is and will be stored.

template<typename Type, int Channels = 1>
QVImage< Type, Channels >::QVImage ( QVImage< uChar, 1 > const &  img  ) 

Copy constructor.

This constructor can be used to construct an image from another one with same bit depth and channel number, or from an image differing in type or number of channels.

In the former case, this constructor will do a copy-on-write, duplicating the pointer to the data buffer of the image, and efectively copying the data only when modifying it if shared by more than one QVImage object.

In the latter case, it will always allocate a new data buffer for the image, and make a conversion from different bit depth or channel number. Note that you can never convert from an image that differs in data type and bit-depth with the constructed image.

This constructor will copy the ROI and anchor of the parameter image.

Parameters:
img image to be copied.

const Type* QVImage< Type, Channels >::getReadData (  )  const [inline]

Method to obtain image data buffer, in read mode.

This method can be used to program fast access algorithms to pixel values in an image.

It is intended to be used only to read pixels in an image, thus getWriteData() method should be used when access to write or read/write is intended to be done.

This function will generally be faster than getWriteData(), because it will not need to realize copy on write, in the case that the image data buffer where shared with other QVImage.

Type* QVImage< Type, Channels >::getWriteData (  )  [inline]

Method to obtain image data buffer, in read/write mode.

This method can be used to program fast access algorithms to pixel values in an image.

This function will perform copy on write in the case that the data buffer for this image where shared with other QVImage's.

Thus can be slower than getReadData() method to access image pixels, but will ensure avoiding side effects on modifying shared buffers with other images.

template<typename Type, int Channels = 1>
void QVImage< Type, Channels >::set ( Type  c1 = 0,
Type  c2 = 0,
Type  c3 = 0 
)

Sets pixel values for an image, to a given value.

This method uses the region of interest of the image, to set pixels inside it to a given value. It can be used either for one channel, or several channel images.

In the former case, it should be used with one parameter, only specifying value for the first channel, otherwise, values for other channels will be ignored. If no parameters are given, the image region of interest will be set to zero value pixels.

In the latter case, default values of 0 will be used if there are unspecified channel values.

Parameters:
c1 value to set pixel's first channel in the region of interest of the image.
c2 value to set pixel's second channel in the region of interest of the image.
c3 value to set pixel's third channel in the region of interest of the image.

const uInt  channel = 0 
) [inline]

Operator to access pixel values for a pixel channel, given it's coordinates.

This operator can be used either with one channel or multichannel images. In the first case, it shouldn't be given a channel number, to use the default zero value.

Parameters:
col column number of pixel to be accessed.
row row number of pixel to be accessed.
channel channel number of pixel to be accessed.

) [inline]

Overload of operator (), to access pixel values for a pixel channel, given a QVPoint and a channel number.

This overload is like the previous, but can be used with a QPoint, to access a concrete pixel in the image.

Parameters:
point QPoint indicating location of the pixel to be accessed.
channel channel number of pixel to be accessed.

template<typename Type, int Channels = 1>
QVImage<Type, 1> QVImage< Type, Channels >::operator() ( const uInt  channel = 0  )  const

Operator to access pixel values for a pixel channel, given it's coordinates.

This operator can be used either with one channel or multichannel images. In the first case, it shouldn't be given a channel number, to use the default zero value.

Parameters:
col column number of pixel to be accessed.
row row number of pixel to be accessed.
channel channel number of pixel to be accessed.

template<typename Type, int Channels = 1>
QVImage<Type, Channels>& QVImage< Type, Channels >::operator= ( const QVImage< uChar, 1 > &  sourceImage  ) 

Copy operator.

Like the copy constructor, this operator can be used to copy an image from another one with same bit depth and channel number, or from an image differing in type or number of channels.

In the former case, this operator will do a copy-on-write, duplicating the pointer to the data buffer of the image, and efectively copying the data only when modifying it if shared by more than one QVImage object.

In the latter case, it will always allocate a new data buffer for the image, and make a conversion from different bit depth or channel number. Note that you can never convert from an image that differs in data type and bit-depth with the constructed image.

The copy operator will copy the ROI and anchor of the parameter image.

Parameters:
img image to be copied.
