Embodiment 1
[0030] Such as figure 1 As shown, a method for dividing image regions based on RGB change trends mainly uses two rounds of similar judgments to divide image regions, and uses the similarity of the change directions of RGB three primary color channels and the proximity of pixel physical positions to determine whether a pixel is a certain region One of the clustering methods belongs to an image preprocessing method.
[0031] Specifically, in this embodiment, the method for dividing the image area based on the RGB variation trend specifically includes the following steps:
[0032] Step S01. accept picture input, the picture input in this embodiment is such as figure 2 The original picture shown, specifically, figure 2 The image shown is actually the image after decolorization of the original image, and in this embodiment, the image information with length X=91 pixels and width Y=27 pixels is obtained from the image.
[0033] Step S02. Read figure 2 The RGB color channel si...
