The invention relates to a graying method based on spectral reflection characteristic and three-color imaging principle which is suitable for a color image with object and local background having color separation characteristic. The method includes steps as follows: firstly, analyzing the spectral reflection characteristic with object and local background in visible light wave band; secondly, comparing difference of two spectral reflection characteristic in three original color wave band of the imaging device; thirdly, defining the color corresponding to the most difference as gray color; finally, graying the color image by using corresponding weight of the gray color in RGB color space. Compared with the prior art, the method has graying function and function for enhancing customized object region contrast from a data source, and also can weaken effect to the image quality by some imaging conditions, such as material pollution, shadow, weak illumination effectively.
Description
Grayscale method based on spectral reflectance characteristics and three-color imaging principle technical field The invention relates to the field of digital image processing, in particular to a grayscale method based on spectral reflection characteristics and three-color imaging principles. Background technique Digital image processing is a technology that uses a computer to perform a series of operations on digital images to obtain certain expected results. Digital image processing is closely related to the development of computing technology and imaging technology, and also involves mathematics, optics, electronics, psychology and other fields. Due to the early start of human research on the mechanism of vision, imaging and digital image processing technology in the visible light band have attracted people's attention. The important three-color imaging mechanism is the design basis of visible light imaging devices. Its principle is to divide the visible spectrum into...
