Hi,
Using ippiConvFull_32f_C3R yeilds very large luminance values. Using a softclip algorithm gives me aesthetic results, but I'd like to inquire about proper post scaling methods for ippiConvFull.
Any thoughts?
Best,
Ryan

Hi,
If you want to normalize the data, is it to divided the kernel by sum of the all kernel value?
Thanks,
Chao

Hi,
I actually just worked that out. Thank you for replying.
Here's the code I used for anyone else who's wondering:

[cpp] //Calculate Sum of Kernel ippiSum_32f_C3R(Ipp_Ker, Ker_StepBytes, Ker_Size, KerScaled, ippAlgHintFast); // Clamp KerScale to 1. for (i=0; i<3; i++) { if (KerScaled > 1) KerScalef = float(1) / KerScaled[0]; else KerScalef = 1; } // Multipy Ker by Inverse of Sum ippiMulC_32f_C3IR(KerScalef, Ipp_Ker, Ker_StepBytes, Ker_Size);[/cpp]
