Abstract

The invention discloses a template subgraph acquisition method and device, a processor and an electronic device. The method comprises the following steps: respectively extracting a plurality of key sub-graphs from each sample of a stick figure data set without a label to obtain a key sub-graph set; performing feature extraction processing on each sample in the key sub-graph set to obtain a key sub-graph feature data set; and performing clustering processing on the key sub-graph feature data set to obtain a plurality of template sub-graphs, wherein the key sub-graph feature data set comprises aplurality of sub-graph feature clusters, and the gravity center of each sub-graph feature cluster in the plurality of sub-graph feature clusters corresponds to one template sub-graph. According to the method and the device, the technical problem that a stick figure recognition mode provided in the related technology is completely characterized by manually designing and extracting rules and does not have a function of characterizing stick figure characteristics is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a template subgraph acquisition method, device, processor and electronic device. Background technique [0002] Stick figures usually refer to extracting the most prominent features of an objective image and expressing a general painting with concise strokes. A template subgraph usually refers to a representative partial image that can reflect the characteristics of a class of images. [0003] Accurate and efficient extraction of template subgraphs from stick figures is of great significance for stick figure recognition tasks. After the template subgraph is extracted, the key subgraph (for a single image) can be matched with the template subgraph (that is, the entire image set, which is equivalent to the set of key subgraphs extracted in multiple images) To obtain the stroke semantic features of stick figures for feature training or matching. [0004] Stick figure recognition u...
