Sažetak
The aim of this paper is to examine a set of wavelet functions (wavelets) for implementation in still image compression system and to highlight the benefit of this transform relating to today's methods. The paper discusses important features of wavelet transform in compression of still images including the extent to which the quality of image is degraded by process of wavelet compression and decompression. Image quality is measured objectively using peak signal-to-noise ratio (PSNR) and subjectively using perceived image quality. The effects of different wavelet functions, image contents and compression ratios are assessed. The comparison with DCT based compression system is given.
