Color constancy at a pixel.

Published by Modified over 3 years ago. The image formation equation: With certain restrictions, from a 3-band color image we can derive a 1-D grayscale zt which is: Tracking result for moving hand under lamp light.


Kodak DCS camera is much less sharp. Try spectral sharpening, since wish to make sensors more narrowband…. Or just optimize directly, making invariant image more invariant.

Should we sharpen to get M? R 2 goes from 0. Scene illumination and surface albedo recovery via L1-norm total variation minimization Hong-Ming Chen Advised by: Convolution and edge detection CS A given pattern p is sought in an image. The pattern may appear at any location in xt image.
