Abstract

The embodiment of the invention provides an object category detection method and device, and the method can comprise the steps: carrying out the object detection processing of a first image through a target detection network, obtaining the first category confidence coefficient of a target object in the first image, obtaining an object image comprising a re-detection object from the first image, and carrying out the detection of the re-detection object. Carrying out object detection processing on the object image through a filter, and determining a second category confidence coefficient of the re-detection object, wherein the re-detection object is a target object of which the first category confidence is within a preset threshold interval; correcting the first category confidence coefficient of the re-detection object based on the second category confidence coefficient to obtain an updated confidence coefficient; and determining a category detection result of the re-detection object according to the updated confidence coefficient. According to the embodiment of the invention, the accuracy of object category detection is improved.

Description

[0001] Cross References to Related Applications [0002] This application claims Singapore Patent Application No. 10202106360P, entitled "Method and Apparatus for Detection of Object Classes", filed 14 June 2021, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to image processing technologies, and in particular to a method and device for detecting object categories. Background technique [0004] Target detection is an important part of the intelligent video analysis system. When performing target detection, we hope to detect the target object (such as a specific object) in the scene with high accuracy, and for the object outside the target object Other items can be collectively referred to as foreign things. These extraneous items may cause false detections in target object detection, affecting subsequent analysis based on the target object. [0005] In related technologies, target objects can be de...
