A Study on Quantization Effects of DCT Based Compression

Abstract

Quantization in discrete cosine transform (DCT) domain is a widely used lossy compression technique in international multimedia compression standards from audio (e.g., MP3) to image (e.g., JPEG) to video (e.g., H.264). Unlike many degradation sources, like sensor noises, quantization errors of DCT coefficients are signal dependent and difficult to isolate and remove, causing serious artifacts in decompressed and post-processed signals. In this …
