Problems solved by technology

Despite the tremendous development in computer vision, there are still great differences between computer vision and human vision, and there are still great differences in the perception of color. The difference in color distribution and space will cause the human eye to perceive color different perception

Embodiment 1

[0081] Execute step 1, using the s-cone image color induction data proposed by Monnier P in 2004 as the data set;

[0082] Execute step 2, read the input color image, use the human eye color sensitivity function of formula 6 to process the input image data, and output;

[0083] Perform step 3 to simulate contrast assimilation in color perception, and calculate the image data processed by the human eye color sensitivity function through the color perception neural network model,

[0084] Execute step 4 to judge whether the obtained result is convergent, if convergent, output the final result, if not, continue to execute step 3 until it converges, and then output.

[0085] Execute step 5, and the output result is the color offset during the color perception process of the computer.

[0086] The invention provides a color perception method based on the color sensitivity function of the human eye, which has the characteristics of simulating the color perception phenomenon of the ...

Abstract

The invention discloses a color perception method based on a human eye color sensitivity function. The color perception method is specifically implemented according to the following steps: step 1, reading the color of an input image; 2, processing an input image by using a human eye color sensitivity function; 3, simulating a comparison assimilation effect in color perception, and taking the imageprocessed by the human eye color sensitivity function as input to enter a color perception neural network model; 4, turning the image obtained in the step 3 to the step 3 for iterative operation until convergence; and step 5, after convergence, calculating and outputting offset to complete color perception, and the method has the characteristic of simulating the color perception phenomenon of human eyes in the color recognition process through the color offset.

Description

technical field [0001] The invention belongs to the technical field of image processing and relates to a color perception method based on the color sensitivity function of human eyes. Background technique [0002] In recent years, with the development of computer vision, there has been a lot of research on computer models of color perception. The color perception phenomenon is an important development direction in computer vision in recent years. Rudd (2010) proposed the direction of brightness sensing (contrast and assimilation) Depends on the width and brightness of the ring around the disc. Vanrell et al. (2011) demonstrated the representation of the color of points in the image that are affected by assimilation and contrast effects in the surrounding environment. Kim (2015) used a biophysical retinal model to simulate the contrast and assimilation phenomenon of brightness proposed by Vanrell, and obtained Qualitatively consistent results for psychophysical data. Song e...
