Investigation of variations to the JPEG Still Image Compression Standard to improve compression ratio

Abstract

"This work investigates the possibility of improving the compression efficiency of the JPEG Still Image Data Compression Standard by varying the quantization matrix with minimal loss of image quality. The quantization matrix is empirically developed based on human visual perception and the transform used for compression. Certain applications with low-resolution requirements may utilize such a variation of JPEG so that storage space is saved.

The wavelet transform incorporates quite a few features that make image compression efficient. An attempt is made to replace the existing Discrete Cosine Transform with the wavelet transform in the JPEG standard and a performance analysis is made"--Abstract, page iii.
