My current research work is focused in image processing and algorithms for CFA interpolation. I'm interested in evaluating the performance of the IPP CFAToRGB and DemosaicAHD demosaicing functionality.
I am new in using IPP library. I have troubles with understanding the meaning of parameter “pTmp” of function DemosaicAHD.
In the function description it is written that: “The algorithm requires “the temporary image pTmp of size (srcRoi.width +6, 30)” to be defined and passed during the function call. Could someone to help me to understand:
What the purpose of the temporary image is and what determines this size for the temporary image?
Which IPP method to use for allocating memory for that image?
