“…In general, the human eye is more sensitive to luminance component of the image. The human eye has a non-linier response toward the drastic changes in intensity level and likely to be processed in different frequency channels 2 . The objective of this research is to develop quantitative measures that can automatically predict perceptual image quality 3 .…”

Colour image carries a certain amount of perceptual redundancy for the human eyes. The human eye is capable of perceiving various levels of colours. The sensitivity of human eye is useful for perceptual visual quality image in image compression. The visual sensitivity of the colour image in terms of image compression can be measured by a psychovisual threshold to generate the quantization tables. This paper will investigate a psychovisual threshold level for Tchebichef moment transform (TMT) from the contribution of its moments. In this paper presents a new technique to generate quantization table for TMT image compression based on psychovisual error threshold. The experimental results show that these new finer quantization tables based on psychovisual threshold for TMT provides better quality image and lower average bit length of Huffman code than previously proposed TMT quantization.

“…Human eye does not perceive directly from the translation of retina stimuli, but it involves complicated psychological inference [3]. The human eye has a nonlinear response toward the drastic changes in intensity level and likely to process them in different frequency channels [4].…”
