Pixel-level classification method, device and equipment and storage medium

The invention discloses a pixel-level classification method, device and equipment and a storage medium. The method comprises: inputting an original picture into an encoder, and obtaining a down-sampling feature map, wherein the size of the down-sampling feature map is 1/2N of the size of the original picture, and N is larger than or equal to 1 and smaller than or equal to 3; inputting the down-sampling feature map into a decoder to obtain an up-sampling feature map, wherein the size of the up-sampling feature map is the same as the size of the original picture; and inputting the up-sampling feature map into a classifier to obtain the classification of each pixel in the original picture. According to the embodiment of the invention, the encoder reduces the original picture to obtain the down-sampling feature map, and the decoder restores the size of the down-sampling feature map to the size of the original picture, so that the classification of each pixel in the original picture can bedetermined subsequently a
