- Step 301 Acquire, for example, two frames of original images before and after;
- a video image data stream is stored in a frame memory of the display device, and two frames of image data F (n-1) , F (n+1) are read therefrom.
- Step 302 Perform sharpening filtering processing on the original frames of the two frames before and after;

Therefore, the sharpening filtering process is required, and the sharpening filtering process is performed to compensate the contour of the image, enhance the edge of the image and the grayscale jumping portion, and filter the low-frequency components of the blurred region for subsequent operations.

Specifically, F (n-1) is subtracted from F (n+1) to obtain F (a) as shown in FIG. 6. Subtract F (n+1) from F (n-1) to get F (b) , as shown in Figure 7. Then, F (a) and F (b) are added to perform a logical operation to obtain a feature image F (c) as shown in FIG.
- Step 304 Perform expansion and erosion operations on the feature image to obtain feature elements that generate smear;
- Expansion and erosion operations are the basis of morphological image processing. In essence, expansion is an operation of "bold” or “thickening” in an image, and etching is an object that "shrinks" or “refines” an image.
