Sažetak
This paper exams the effects of wavelet based compression to image quality. Image quality is measured objectively using peak signal-to-noise ratio (PSNR) and subjectively using perceived image quality. The results of image quality measurements for different wavelet functions, image contents and compression ratios are given. The relationship between results of objective picture quality testing and the perceived quality is considered. The comparison with JPEG picture quality for different compression ratios is presented.
