I have a set of 70 RGB images (argc=71). I wanted to change pixel values according to these formulas:
l1 = (R-G)^2/((R-G)^2 + (R-B)^2 + (G-B)^2);
l2 = (R-B)^2/((R-G)^2 + (R-B)^2 + (G-B)^2);
l3 = (R-G)^2/((G-B)^2 + (R-B)^2 + (G-B)^2);
And then store the new images. The code I tried using c++ is below but I keep getting this error:
SetPixels(99556,0x7fff76450000) malloc: *** error for object 0x10a9ce000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Can anyone help me solve this matter?
Thanks in advance!
