Output Semantic Segmentation Result.

Description

technical field [0001] The invention belongs to the scene understanding technology in the fields of computer vision, pattern recognition, deep learning and artificial intelligence, and in particular relates to the technology of pixel-level semantic segmentation of the scene using a deep convolutional neural network in an image or video. Background technique [0002] Such as figure 1 As shown, in order to increase the receptive field of the deep network and reduce the amount of calculation, the backbone part of the existing deep convolutional neural network is usually down-sampled by 1 / 2 times 5 times to 1 / 32 times the input image. After multiple times of downsampling, the features of small objects and the details of objects (such as edge parts) are gradually fused by the surrounding pixel areas, and the distinguishability of small object features continues to decline. Existing representative semantic segmentation methods based on deep neural networks, such as FCN [1], direc...

Problems solved by technology

[0011] The purpose of the present invention is to overcome the problem that the existing semantic segmentation method based on pixel-by-pixel classification does not consider the structure of similar continuous pixel regions and the structural differences of different types of adjacent pixel regions, and at the same time, in order to improve the accuracy of small objects and object details Semantic segmentation, a semantic segmentation network that integrates multi-scale feature space and semantic space is proposed
