Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, the color blindness correction method based on subregional mapping provided by the embodiment of the present invention includes the following steps:

[0033] S101: Calculate the ratio ratio1 between the number of pixels of R>G and the number of pixels of R<=G;

[0034] S102: Calculate the ratio ratio2 of the number of pixels of R+G=255;

[0035] S103: Map the colors of R=255 to part II, map the colors of R>=G and R+G>=255 Colors are mapped to Part ...

Abstract

The invention belongs to the technical field of color blindness correction and discloses a color blindness correction method based on regional mapping, which includes: counting the ratio ratio1 of the number of pixels with R>G and the number of pixels with R<=G; counting R+G<255 The ratio of the number of pixels to the number of pixels R+G>=255 ratio2; map the colors of R<G and R+G<255 to part I, and map the colors of R<G and R+G>=255 to part II Part, map the colors with R>=G and R+G>=255 to the III part, map the colors with R>G and R+G<255 to the IV part, while keeping the R and G components unchanged. Experiments of the invention show that patients with color blindness can distinguish processed images very well, and the efficiency of the invention is better than other existing color blindness correction algorithms, and the computing performance basically meets the requirements of real-time processing.

Description

technical field [0001] The invention belongs to the technical field of color blindness correction, and in particular relates to a color blindness correction method based on subregional mapping. Background technique [0002] Relevant data have shown that about 8% of men suffer from various types of color blindness, and at the same time about 0.5% of women suffer from various types of color blindness. This proportion may not be too high, but after multiplying by the huge population base, it is a A number that cannot be ignored. Color-blind patients have many inconveniences in real life. No matter what kind of color-blindness the color-blind patients suffer from, they will always encounter various troubles in life, which seriously affects their quality of life and reduces their work. efficiency. If color blindness correction is not carried out, such troubles will accompany them throughout their lives, because color blindness is irreversible, and until now there is no scientif...
