From: sweety on 28 Mar 2010 01:30 how to enhance the contrast of image using wavelet. plz tell me the code
From: sweety on 28 Mar 2010 01:34 i have a 100*100 image and take a block of 20*20. i tell this u by my code a=imread(''); a=rgb2gray(a); a=imresize(a,[100,100]); b=a(1:20,1:20); e=edge(b,'sobel'); then tell me how i can calculate number of edge pixel

You really should use more descriptive variable names - you'll appreciate that once you get longer and more sophisticated programs as it will help you understand and maintain your code later. But it's a good habit to get into now.
