I have a two channel image and I need to do a low pass filter on the image. I only see support for 1,3,4 channels. Should I use 16u_C1R mod and divide the steps by two? The layout of the image is 4:2:2.
If your image 4:2:2, 2channel is like YCrYCbYCrYCb.... there may two problems cause wrong result finally. 1. two 8udata != 16u 2.as low pass filter will use the neighbor pixer, you may mix Cr and Cb into computation.
You may need check the ipp reference manual to choose some suitable functions or functions combination to do this.
