Separable Gaussian Blur using custom kernel?

[levicki]

Why IPP doesn't have separable Gaussian Blur filter with the option to use custom filtering kernel / weight matrix?

[levicki]

Will anyone be so kind to answer this?

Hi Igor,

inspite it is not the same but you might be interesting to see the following thread

Generalized Gaussian Blur, borders and filters for whole images

But, to make it clear, when you say gaussian filter, is not it specify kernel exactly? Why do you need custom kernel it that case?

Hello Igor,

Take a look at ippiFilterGaussBorder_32f_C1R, declared in ippcv.h (IPP 5.2+)
If you need to process 8-bit or 16-bit image, you may use generic
functions for separable convolution: ippiFilterRow* and ippiFilterColumn*.

But I need to set radius or weighting for blur, not have it fixed.
