Alma Technologies Introduces an Online Tool for Comparison of Image Compression Standards

Athens, Greece, May 17, 2017 -- An online tool for back-to-back comparison of the image compression standards implemented by our IP cores is now available on our website. The Bit Accurate Models of the respective image compression cores are used to encode / decode a user supplied test image, in order to evaluate and compare their actual performance.

This tool is very useful for evaluating the compression efficiency at various compression ratios. The user uploads a test image, sets the target compression ratio and the tool compresses and decompresses this image with all supported algorithms. The reconstructed image, the achieved compression ratio, the PSNR and the Structural Similarity (SSIM) metrics are put together in comparison graphs for easy evaluation of each image compression standard. For lossless algorithms where the output image is bit-by-bit identical to the input image, the achieved compression ratio is displayed only.

The following standards are compared back-to-back:

Lossy mode Compression Standards
JPEG vs JPEG 2000 vs CCSDS 122.0-B-1 vs H.264 All-Intra

Lossless mode Compression Standards
JPEG-LS vs JPEG 2000 vs CCSDS 122.0-B-1
