[JAI] RGB to YCC to RGB
I'm working on watermarking, which involves modifying image data on
the frequency domain after converting it to YCC. My problem is the
I get a YCC colorspace image (CS_PYCC), I convert it to its original
colorspace (RGB), and I store it. The problem is that when I open it
again and convert it to YCC I get different data. For example, the 4
first coefficients of the YCC image are 223, 5, 218, 66, which turn to
247, 3, 246, 247 in RGB. The issue is that when I try to convert them
to YCC again I get 205, 4, 202, 66, which is perceptually good enough,
but not good enough to evaluate watermarking...
Could someone help me?
Thanks in advance
