ADCT: A NEW HIGH QUALITY DCT BASED CODER FOR LOSSY IMAGE COMPRESSION


ADCT is state-of-the-art lossy image compression method providing the best ratio-distrortion performance in the scientific literature. ADCT is FREE for scientific use.

A research version of the coder (only for Photoshop grayscale RAW images coding) and test images are given below:

adct.zip (50 Kb) - ADCT.
testset1.zip (3 Mb) - set of 512x512 grayscale test images (16 images).
testset2.zip (25 Mb) - set of 2288x1712 grayscale test images (8 images).
