[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] refer to figure 1 , the steps that the present invention realizes are as follows.
[0033] Step 1 Load the image and perform superpixel preprocessing
[0034] GrabCut image segmentation based on pixel level is time-consuming, so it is necessary to apply superpixel preprocessing to speed up. A superpixel is a small area composed of a series of adjacent pixels in an image with similar characteristics such as color, brightness, and texture. The Simple Linear Iterative Clustering (SLIC) algorithm is proven to be the best superpixel segmentation method currently. SLIC converts LAB color space and coordinate space into 5-dimensional vectors. Most of the small areas of superpixels retain effective information for further image segmentation, and generally do not destroy the boundary information of objects in the image. The algorithm sets the superpixel si...
