Visual perception law for two-dimensional stimulus

Object: To study the quantitative relationship between stimulus quantity and perception quantity of human vision for two-dimensional stimulus. Methods: Firstly, the quantitative theory of the quality perception of two-dimensional stimulus was constructed, then the method to measure the quantitative relationship between the quality of the stimulus and the quantity of the stimulus was established. Finally, the relationship between the perception quality of human vision for an image and the luminance of the image was experimentally verified. Results: Results shows the quantitative of the psychophysical perception quality for two-dimensional stimulus was realized and there is a convex and non-linear relationship between the perception quality of human vision for an image and the image luminance, and directly applied it to measure the visual quality of the image. Conclusion: The research result will lay the foundation of image quality assessment and image enhancement theory and technology as well as related industries.
