Image texture detail enhancement method for color vision disorder

Abstract

The invention discloses an image texture detail enhancement method for the color vision disorder. The method comprises the following steps: (1) converting an image color space into an LMS color space;(2) respectively extracting details of L, M and S channels in an LMS space for a patient with the color vision disorder of a specific type; (3) adding the details extracted in the step (2) to color channels which are corresponding to the image processed in the step (1) and can be perceived by other two color impaired people of the type, the obtained image being a final enhanced image; and (4) converting the LMS color space back to the RGB color space for display or storage. According to the texture detail enhancement method provided by the invention, the richness of image detail textures of apatient suffering from the color vision disorder at a visual angle is well improved, and since part of texture details of the image are extracted, the image quality and visual perception after colorcorrection are improved while the authenticity of the image is ensured.

Description

Technical field [0001] The invention relates to an image texture detail enhancement method for color vision disorders. It belongs to the technical fields of computer vision, image processing and color correction. Background technique [0002] Human perception of external information is mainly composed of five parts: vision, hearing, smell, taste and touch. Among them, visual information is the information with the highest information entropy, and color information is an important part of visual information. There are two types of cells in the human retina: rod cells and cone cells. The rod cells are sensitive to the intensity of light and perceive light and darkness; while there are three types of cone cells, which are sensitive to red, green, and blue light. , Perceive color. Because these three types of cone cells are sensitive to long, medium, and short spectra, these three types of cone cells are usually expressed as long (L), medium (M), and short (S) cones. When the vis...

Problems solved by technology

However, due to the abnormality of the pyramidal cells, patients with color vision disorders can not accept normal colors, but also have adverse effects on the perception of image texture.

For example, a patient who is born without M cone cells cannot perceive the texture details of the color that the M cone cells should receive.
