I'm very new to OpenCV and attempting to do something which seems simple, but execution for an amateur is difficult.
I have to iterate through every pixel in an image, perform some math on the current pixel's RGB values (Red-Blue/Red+Blue), and output an image (in HSL) with a hue:
newHue = (ndvi-.5)*(-360)
and a saturation & brightness of 1 (constant across the output image).
Any tips on getting started with something like this?
