ActiveCN108876792AImprove processing effectAccurate Semantic Segmentation ResultsImage enhancementImage analysisConvolutionDeconvolution
The embodiment of the invention provides a semantic segmentation method, a semantic segmentation device, a semantic segmentation system and a storage medium. The method comprises the steps of: obtaining an image to be processed; and inputting the image to be processed into a U-shaped network, so that a semantic segmentation result of the image to be processed output by the U-shaped network is obtained, wherein the contraction path of the U-shaped network comprises n convolutional modules, which are connected in sequence; output features of the ith convolutional module in the n convolutional modules are combined with output features of at least one convolutional module after the ith convolutional module; the combined features are in jump connection with the output end of a deconvolution layer in the contraction path of the U-shaped network and corresponding to the ith convolutional module, wherein n is an integer, which is greater than 1; and i is greater than or equal to 1 and less than n. According to the semantic segmentation method, the semantic segmentation device, the semantic segmentation system and the storage medium in the embodiment of the invention, because of adoption ofshallow features and deep features, the U-shaped network can be well improved in a fusion manner; and thus, a relatively accurate semantic segmentation result can be obtained.
