How can I perform arithmetic operations with pixel value in c++ using opencv? -

i have set of 70 rgb images (argc=71). wanted change pixel values according 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 store new images. code tried using c++ below keep getting error:

setpixels(99556,0x7fff76450000) malloc: * error object 0x10a9ce000: pointer being freed not allocated * set breakpoint in malloc_error_break debug

can me solve matter?

thanks in advance!
