Embodiment Construction
[0068] In this embodiment, a viewpoint tracking method based on geometric reconstruction and semantic fusion, such as figure 1 As shown, follow the steps below:
[0069] Step 1. Construct the visual feature set of the sub-image: this stage is mainly to obtain the visual feature matrix containing color features, texture features and geometric structure features of the source image;
[0070] Step 1.1, use the clustering method to divide the source image into l sub-regions, use each sub-region as a node, construct a sub-graph containing several nodes, and obtain the sub-graph set G={G 1 ,G 2 ,...,G n ,...,G N}, N represents the total number of subgraphs; G n Represents the nth subgraph in the subgraph set G, and has Indicates that the nth subgraph contains t n nodes; and means G n Middle t i nodes; E n means G n middle t n A set of geometric connection edges between nodes, and the connection edges must ensure that G n It is a connected graph with the number of ...
