radiometric calibration for a digital camera using a color chart? 
  Hi all, I know a good way to radiometrically calibrate a low-cost camera (which uses a color filter array) is using a uniformly illuminated color chart (such as Macbeth color chart). However, I do not know exactly how to do it. I have some experiences with colorimetric calibration for a scanner with a Q-60 target. I am... more »

How to generate a perceptual 2-dimensional color map... 
  Hello, I want to define a colormap f based on 2 parameters X and Y, such that when drawing a patch with a color f(x,y), I shall perceptually infer from that color f(x,y) the values X=x and Y=y for the two parameters. What could be a colormap perceptually relevant for this task? I tried using interpolated color map from RGB space such that : f(0,0)... more »
