Abstract

The embodiment of the invention provides an isomorphic pattern recognition method and device, equipment and a medium. The method comprises the steps: receiving a target graph and a mode graph, wherein each of the target graph and the mode graph comprises nodes and edges connected with the nodes; screening the nodes in the target graph based on the labels of the nodes in the target graph and the labels of the nodes in the mode graph, and obtaining a sub-graph of the target graph according to the screened nodes in the target graph; and searching the mode graph in the sub-graph of the target graph to obtain an isomorphic graph of the mode graph. According to the embodiment of the invention, the efficiency of identifying the isomorphic pattern of the mode pattern from the target pattern is improved, and the time complexity and time consumption of identifying the isomorphic pattern of the mode pattern from the target pattern are reduced.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method, device, equipment and medium for isomorphic graph recognition. Background technique [0002] In related technologies, with the continuous development of computer and information technology, more and more data represented by graphs appear. In the fields of bioinformatics, social networks, and integrated circuits, it is necessary to use isomorphic graph recognition technology to identify isomorphic graphs that are isomorphically matched with pattern graphs from a large number of target graphs. Due to the huge number of nodes that need to be matched in the target graph, this reduces the efficiency of identifying the isomorphic graph of the pattern graph from the target graph, thus increasing the time complexity and time consumption of identifying the isomorphic graph of the pattern graph from the target graph. Contents of the invention [0003] In view of the ...
