is highly adapted for extracting structural information from a scene, we introduce an alternative complementary framework for quality assessment based on the degradation of structural information. As a specific example of this concept, we develop a Structural Similarity Index and demonstrate its promise through a set of intuitive examples, as well as comparison to both subjective ratings and state-of-the-art objective methods on a database of images compressed with JPEG and JPEG2000. A MATLAB implementation of the proposed algorithm is available online at http://www.cns.nyu.edu/~lcv/ssim/.

Imaging systems may introduce some amounts of distortion or artifacts in the signal, so the quality assessment is an important problem. morefromWikipedia Protein structure In molecular biology protein structure describes the various levels of organization of protein molecules. Proteins are an important class of biological macromolecules present image quality assessment in all organisms. Proteins are polymers of amino acids. Classified by their physical size, proteins are nanoparticles . Each protein polymer ¿ also known as a polypeptide ¿ consists of a sequence formed from 20 possible L-¿-amino acids, also referred to as residues. morefromWikipedia JPEG 2000 JPEG 2000 is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created in 1992) with a newly designed, wavelet-based method. The standardized filename extension is . jp2 for ISO/IEC 15444-1 conforming files and . jpx for the extended part-2 specifications, published as ISO/IEC 15444-2. morefromWikipedia JPEG In computing, JPEG is a commonly used method of lossy compression for digital photography (image). The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. JPEG compression is used in a number of image file f
