Description

This function operates with ROI.

The

ippiFilter

function uses the general rectangular kernel of

kernelSize

size to filter an image ROI. This function sums the products of the kernel coefficients

pKernel

and pixel values taken over the source pixel neighborhood defined by

kernelSize

and

anchor

. The anchor cell is specified by its coordinates

anchor.x

and

anchor.y

in the coordinate system associated with the bottom right corner of the kernel.

Kernel coefficients are used in inverse order. The sum is written to the destination pixel.

To ensure valid operation when image boundary pixels are processed, the application should correctly define additional border pixels (see Borders in Neighborhood Operations).

This function

requires a temporary work buffer. Before using this function flavor, you need to compute the buffer size using the

ippiFilterGetBufSize

function.
