In color theory we describe two colors that have absolute chromatic contrast as complementary because when used with additive or subtractive light mixing, they complete the color spectrum and produce an achromatic result. You may know these simply as opposite colors. Green, for example, is often said to be the opposite of red.
A method and system for chrominance contrast enhancement
The application provides a chroma contrast enhancement method, which comprises the following steps: transforming a first pixel from a first color space to a second color space; combining the two chroma components of the first pixel into a vector and calculating the length of the vector when the luminance component is between a preset maximum luminance and a preset minimum luminance; calculating an amplification coefficient of the first pixel according to the length of the vector; enhancing the two chroma components of the first pixel by using the amplification coefficient, wherein the two enhanced chroma components and the luminance component of the first pixel constitute a second pixel; and converting the second pixel from the second color space to the first color space to obtain the first pixel after enhancement. The chroma contrast enhancement method provided by the application can increase the difference between pixel colors while keeping the luminance of the pixel unchanged.
