I am a Google Summer of Code Student working with Public Lab. I am working on the Image Sequencer Project.
This is the GitHub Issue where Jeff and I were discussing about this.
I replace every pixel of the image using this algorithm:
input pixel => (r,g,b,a) ndvi = (b - r) / (b + r) x = 255 * (1 + ndvi) / 2 output pixel => (x,x,x,a)
Is this correct?
