[0026] Filtering processing: Median filtering is used, and the window scanning path is S-shaped, that is, the window moves to the right first, when it reaches the rightmost end, the window moves down by one pixel, and then the window moves to the left, and when it reaches the leftmost end, the window moves downwards Cycle by moving one pixel, then right again, until the entire image is scanned. When the window moves one pixel, the local histogram in the window does not need to be re-statistical. When the window moves to the right, just subtract the leftmost pixel of the window from the histogram, and add the pixels in the right column outside the window at the same time; When the end of a line is reached, the pixels in the top row of the window are instead subtracted from the histogram, and the pixels in the next row outside the window are added; when the window is moved to the left, just the pixels in the rightmost row of the window are subtracted from the histogram Subtract ...
