Entropy of image

Started by Sylvia July 30, 2009
Hi,
For a 2D image with intensity values I(x_i) where x_i is the location of
ith pixel within the image, is there any relationship (correlation etc.) of
following expression

sum_i I(x_i) log (I(x_i)) 

 with the entropy of an image?

Look up entropy, entropy power inequality, and vector entropy inequality Maurice Givens
