Is it possible to calculate energy, contrast, homogeneity, etc by using approximate coefficients of 2D-DWT and the histogram of LL Band image of 2D-DWT. I didn't use GLCM for some reasons.
Look at papers in Prof. Eero Simoncelli's group for extracting image statistics using Gaussian pyramids (multiscale)
they also have matlab code
Thank you, sir. I am searching the papers right now.
I found that Hough Transform is used for skew detection and correction but I don't know how it is work. The input image is scanned paper currency and I want to correct the angel.
