| 2016-04-05 01:16:50 -0600 | asked a question | Math on every pixel to Calculate NDVI? 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: and a saturation & brightness of 1 (constant across the output image). Any tips on getting started with something like this? |
