| Summary: | A psychovisual threshold is developed based
on the psychoacoustic quite threshold. Psychovisual
threshold is obtained from quantitative experiments by
evaluating the just noticeable difference (JND) at
various frequency orders. Psychovisual threshold is
suitable to be implemented in image compression and
image watermarking applications. In image
compression, the experimental results produced largely
free artifacts in the visual output image and better
image quality at the higher compression rate than JPEG
image compression. This technique is suitable to be used
in image watermarking, the experimental results
indicated that the proposed scheme can achieve high
imperceptibility and robustness. |
