jvqa 1.0-alpha-8
March 3, 2015

Video Quality Assessment in Java. Built upon Java Native Access for Avisynth - jnavi (https://sourceforge.net/projects/jnavi).

Based on the Fast Structural Similarity index proposed by Chen and Bovik: http://live.ece.utexas.edu/publications/2011/chen_rtip_2011.pdf

Implements the original, variance-based SSIM, Multi-Scale SSIM, Fast SSIM, 2, 3 and 4-Component Weighted SSIM, and Gradient Magnitude Similarity Deviation. Indexes may be customized by selecting image structure statistic (variance, gradient, shifted gradient, 2/3/4-component gradient of variance), structure scale (full, downsampled to 256 or multiscaled), pooling window type (Gaussian, Box, Box with downsampling, or unfiltered) and size, index stabilization (logical or by constants) and luminance index (Gaussian, Box, Box with downsampling or no luminance index).
