The invention relates to a video semantic segmentation method based on attention, and belongs to the fields of computer vision, deep learning and the like. Comprising the following steps: acquiring a training sample set and a test sample set; building a network model; sending attention features and query frame features output by an attention module into a segmentation head for feature fusion to obtain a segmentation result graph; training the network model; and model parameters are stored after a model optimal mode is gradually achieved. The method has the advantages that the time sequence of the video frame is fully utilized to improve the segmentation precision, the calculation amount is reduced while the segmentation precision is kept by adopting the large kernel decomposition convolution, the context information and the object region category information can be extracted from the three aspects of space, channel and object category by using the multi-polarization attention network, and ...

The invention provides a reversible 3D polygonal grid data hiding algorithm based on segment displacement. The algorithm mainly includes an information hiding part and an information extracting part, wherein the core part is information processing conducted through a 3D grid, normal control coordinates and normal label information are acquired and segmented, information hiding and information extraction are conducted, and finally a processed 3D grid model is acquired through model reconstitution. According to the hiding algorithm, a segmenting hiding strategy is adopted in the model, so that a hiding error is controlled within a small and controllable range, a user is capable of hiding infinite information on the 3D grid model, the high signal to noise ratio is guaranteed, and the problem that the information hiding amount and the signal to noise ratio are contradictory directly is really solved. As a new 3D model information hiding mode, the reversible 3D polygonal grid data hiding algorithm ...
