Sheikh, Eero P. Simoncelli, En-Hui Yang and Alan C. Bovik "Quaity-Aware Images," IEEE Transactions on Image Processing, accepted for publication, 2005. ------------------------------------------------------------------ Usage: 1) Download the required files, which include (i) this zip file; (ii) the matlabPyrTools for wavelet analysis (available at http://www.cns.nyu.edu/~eero/software.html) (iii) Matlab optimization toolbox 2) Unpack the zip file into a directory, respecting the original tree structures of the package 3) Set Matlab path to inculde the wavelet analysis routines 4) To test the encoder: run the "test.m" program under directory qaware_encoder. This results in a quality-aware image named "qa_img.tif" in the same directory. 5) To test the decoder and quality analyzer: (a) copy "qa_img.tif" to directory qaware_decoder; (b) run the "test.m" program there. The "test.m" program simulates several types of distortions and evaluate the quality of the distorted image. =================================================================== Please report to [email protected] for any bug or comment.
