[0033] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the text of the description.
[0034] A method for performing texture analysis on a video image intra coding unit, using a first texture complexity to perform texture analysis on a video image intra coding unit, where the first texture complexity is the local range of all pixels of a coding unit The variance of the value, wherein the local range value refers to the difference between the maximum pixel value and the minimum pixel value in a local range of a pixel, and the local range refers to other adjacent pixels around the pixel.
[0035] Such as figure 1 As shown in, (a) is a coding unit. For a pixel with a pixel value of 6 in (a), its local range includes pixels with pixel values of 1, 2, 3, 5, 7, 9, 10, and 11. Pixels, so the local range value is the difference between the maximum pixel value o...
