Function Documentation

void Filter ( const QVImage< sFloat > &  src,
QVImage< sFloat > &  dest,
const QVMatrix  kernel,
const QPoint &  destROIOffset = QPoint(0, 0) 
)

This function uses the general square kernel defined in the matrix kernel to filter an image, using a convolution operation.

Parameters:
src source image to filter.
dest destination image to hold the resulting image after filtering.
kernel matrix containing filter kernel.

Note:
ojo, quizás haya que indicar en IPP_POINT(0,0), el último elemento de la matriz 'kernel', tal y como pasa en las funciones FilterColumn y FilterRow.

Definition at line 333 of file qvipp.cpp.

void FilterColumn ( const QVImage< sFloat > &  src,
QVImage< sFloat > &  dest,
const QVVector  kernel,
const QPoint &  destROIOffset

Parameters:
src source image to filter.
dest destination image to hold the resulting image after filtering.
kernel vector containing the kernel to filter.
Note:
Ojo: muerte, peligro. Hay que indicar como anchor, el tamaño del kernel (menos 1). La iteración irá desde el valor 'kernelSize', hacia abajo.

Applies Gauss filter with border.This function applies the Gaussian filter to the source image ROI pSrc. The kernel of this filter is the matrix of size $ kernelSize x kernelSize $ with the standard deviation $ sigma $. The values of the elements of the Gaussian kernel are calculated according to the formula:

\[ G(i,j) = e^{\displaystyle-\frac{\displaystyle(K/2-i)^2 + (K/2-j)^2}{\displaystyle2\sigma^2}} \]

and then are normalized. The function requires a working image buffer whose size should be computed by the function FilterGaussGetBufferSize beforehand.

Parameters:
src source image to apply filter
dest resulting image.
buffer buffer image initiated beforehand by the function FilterGaussGetBufferSize.
kernelSize specifies the size of the Gaussian kernel, must be odd and greater than or equal to 3.
sigma standard deviation of the Gaussian kernel.
borderType type of border. Following values are possible:

  • ippBorderConst. Values of all border pixels are set to constant.
  • ippBorderRepl. Replicated border is used.
  • ippBorderWrap. Wrapped border is used
  • ippBorderMirror. Mirrored border is used
  • ippBorderMirrorR. Mirrored border with replication is used
borderValue The constant value to assign to the pixels in the constant border (not applicable for other border’s type).
