Doubt about Image operation

[enricbosch2002]

Hello,

I have a question about image operation. I want to do the Radon Transform. That Radon transform consists to make the sum of the columns pixel values, and put the value into another image, and then rotate. IPP have rotate funtion, and this it's no a problem.

If I use an image depth 8U, I lose information because the sum it's higher than 255.

But if I use an image depth 32F, I don't know how to sum the pixel values because each pixel have 4 bytes.

I would be very grateful if anyone could help me.

Thank you.

Hi, Enric,

IPP nas no functions for summation of rows or columns of 8u images

But there are such functions for 16s data (Vol 1 pp 8-9 - 8-12)

ippsSumColumn_16s32s_D2Sfs

ippsSumColumn_16s32f_D2

ippsSumRow_16s32s_D2Sfs

ippsSumRow_16s32f_D2

Note: these functions require row step in elements not in bytes
