[0054]The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0055]The present invention provides a lightweight semantic segmentation method based on multi-scale visual features, such asfigure 1 As shown, specifically, follow these steps:
[0056]Step 1, build a lightweight convolutional neural network LTNET based on multi-scale feature extraction, extract the image characteristics by feature extractor, extracting the image multi-scale feature of the characteristic incoming fusion hole convolution, and finally sampling by simply sampling The module completes feature integration, restores image resolution;
[0057]Its network structure is divided into three modules: 1) Feature extraction module; 2) Multi-scale fusion module; 3) on the sample module;
[0058]After the image input network, first sample extract characteristics by the feature extraction module, then fuse the context information, and extract the image multi-scal...
