[0030] Such as figure 1 Shown, a kind of blind element filling method based on dual-port RAM, comprises the following steps,
[0031] S1, traverse each pixel in the image, and use each pixel in the image as the central pixel to perform a sliding window operation of (2n+1)*(2n+1), and calculate each of the sliding windows The pixel median value of the non-central pixel in the center; wherein, n is a positive integer;
[0032] S2, respectively taking the difference between the pixel median value of the non-central pixel point in each of the sliding windows and the pixel value of the central pixel point of the sliding window and taking the absolute value, correspondingly obtaining the pixel deviation value of each central pixel point of the sliding window ;
[0033] S3. Comparing the pixel deviation value of each central pixel point of the sliding window with a preset pixel deviation threshold, and correspondingly determining whether each central pixel point of the sliding wind...
