Claim 13:
14. The electronic device according to claim 12, wherein the processor:
acquires a degree of each node in each sub-graph of the plurality of sub-graphs, wherein the degree refers to a number of connecting edges between the node and other nodes, and one connecting edge between the node and a node in the same depth layer, and each node in each sub-graph is a depth pixel corresponding to each node in the first three-dimensional model;
obtains a plurality of depth edge node aggregations based on a node having an octa-connectivity domain direction aggregation degree less than a preset degree value, wherein the depth edge node aggregation refers to a set of depth pixels located at the edge of the same depth layer; and
performs uniqueness detection on a node in each depth edge node aggregation to determine each node belongs to a background pixel or a foreground pixel, and obtains a plurality of depth edges corresponding to the first three-dimensional model.
