Popis: | Various structural effects of applying DCT based JPEG compression have been identified. Image quality is dependent upon viewing conditions, image size and pictorial content, in addition to the type and degree of compression applied. RMS error correlates reasonably well with subjective blending distance under the viewing conditions used. Under certain viewing conditions some JPEG induced distorsions may improve subjectively assessed quality. For instance Gibb's rings increasing sharpness. In some circumstances JPEG compression produces noticeable changes in colour reproduction |
