Abstract
AbstractIn this paper, we present a new no‐reference (NR) image quality evaluation model for Joint Photographic Experts Group (JPEG) and JPEG2000 coded images. The proposed model is based on the blockiness around the block boundary, average absolute difference between adjacent pixels within the block, and zero‐crossing (ZC) rate within the block of the image. Subjective experimental results of the Laboratory for Image and Video Engineering (LIVE) Image Quality Assessment Database were used to train and test the model, which achieved sufficient quality prediction performance.
