Embodiment Construction
[0032] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, the present invention has designed a kind of image edge extraction method based on color block point set feature, and this method realizes image edge extraction based on 4 color block point set features, and method specifically comprises the following steps:
[0034] S1. Preprocessing the color image Img1, converting and storing it as a grayscale image Img2. The specific implementation uses the used grayscale conversion function to convert the three-channel color image into a single-channel grayscale image.
[0035] S2. Set the pixel threshold T of the pixel according to specific requirements. The threshold T is adjusted according to the need during specific implementation. The larger T indicates the higher contrast of the edge, and the smaller T indicates higher requirements for the details of the edge.
[0036] S3. Use the ...
