Image rapid edge extraction algorithm used in DSP (Digital Signal Processor) system

[0015] Best practice

[0016] figure 1 Is a schematic diagram of the existing algorithm;

[0017] figure 2 It is a top-down state diagram describing the algorithm of the present invention;

[0018] image 3 Yes figure 2 The bottom-up scanning state diagram of the algorithm shown.

[0019] In the fast image edge extraction algorithm of the DSP system of the present invention, the targets are m, m+1, and the algorithm includes the following steps:

[0020] (1) Cut the target and perform image binarization processing;

[0021] (2), figure 2 As shown, the target is scanned from top to bottom as a whole, and from left to right in each line; when the x-th line is scanned horizontally, when the black point is reached, it is regarded as the left end point of the nth line segment, and it is marked as the th The line segment to which m targets belong; when the right edge is the right edge of the image, or the right is a white point, it is defined as the right end point of the nth line segment;
