Video Enhancement through Image Registration using SSIM

MATLAB Files
File Description
ssim_index_MAT.m It is a modified version of Wang’s ssim_index.m, in which it returns the Structural Dissimilarity of two images, and also, the size of returned map image is equal to the input images.
LK_MAT.zip homo_fa_MAT.m, homo_fa_lm_MAT.m, homo_fa_lm_MAT_SSIM.m, demonstrating the LK-algorithm (LK), LK-algorithm with Levenberg-Marquardt optimization approach (LK-LM) and the proposed LK-algorithm based on SSIM criterion (LK-SSIM-LM). Some of the other files are hessian.m, init_h.m, jacobian_h_MAT.m, quadtobox_H_MAT.m, sd_images.m, sd_update.m, warp_h_MAT.m. The above files are those which are modified according to our requirements, the original files can be downloaded from here.
run_homo_MAT_10_LM.m This file is the main file which uses the above files for mapping a HR training image onto the LR image. For running it, the following packages also are required:
Peter Kovesi's files, which should modify to use Dr. David Lowe's SIFT key-points extraction program for estimation of registration parameters.
reports_SSIM_05.m This file calls run_homo_MAT_10_LM.m for every frame of a sequence and plots some figures in the paper. This files uses MATLAB 2009 instructions for distributing the work over cores of a multi-core CPU, so that the related experiments for each SNR runs on a different core.
Dr. Vandewall SR software This software has been used for comparing with different SR approaches.
