Image segmentation method and device

An image segmentation method and device. The method may comprise: segmenting an image to be segmented into several superpixels according to a pre-set first segmentation rule, to obtain a superpixel image; taking various superpixels as centres, cutting a pre-set scale of image on the superpixel image, so as to obtain image blocks corresponding to the various superpixels; using a neural network to process the image blocks corresponding to the various superpixels, to obtain segmentation class labels corresponding to the various superpixels; segmenting the superpixel image according to a pre-set second segmentation rule, to obtain a segmentation image comprising at least two areas, wherein the second segmentation rule refers to segmenting superpixels with the same segmentation class label into the same area. The method and device can improve the segmentation effect of image segmentation.
