Embodiment Construction
[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0058] This embodiment provides an image vectorization processing method based on boundary extraction and color reconstruction. see figure 1 As shown, the image vectorization processing method based on boundary extraction and color reconstruction includes the following steps S1-S6:
[0059] Step S1, calculate the edge saliency of each pixel in the raster image to be processed based on the gradient information; wherein, the total number of pixels on the raster image to be processed is marked as n, and the jth pixel in the raster image is marked as q j , the pixel q j The marginal significance of is marked as s(q j ), 1≤j≤n;
[0060] In step S1 of this embodiment, when extracting the boundary of the raster image to be processed, the edge saliency of each pixel in the raster image to be processed is calculated based on the gradient informatio...
