Presentation object determining method and apparatus based on image content, medium, and device

摘要

Aspects of the disclosure provide methods and apparatuses for determining a presentation object. In some examples, an apparatus for determining a presentation object includes processing circuitry. The processing circuitry extracts a feature of an object in an image and determines, according to the feature of the object, first feature similarities between the object and a plurality of class nodes. Each class node is associated with at least one leaf node, and each of the class nodes and the leaf nodes is associated with one presentation object. The processing circuitry selects a subset of the plurality of class nodes according to the first feature similarities and calculates second feature similarities between the leaf nodes associated with the selected subset of the plurality of class nodes and the object. The processing circuitry selects a predetermined quantity of presentation objects according to the first feature similarities and the second feature similarities.
