Abstract

The invention discloses a classifier construction method for target detection and a target detection method. The classifier construction method comprises a negative sample generation process, a positive sample generation process and a classifier conformation process, wherein the negative sample generation process comprises the steps of processing an obtained scene original image set to obtain a background set not containing a target and generating a negative sample according to the background set; the positive sample generation process comprises the steps of processing a positive sample original image set containing the target to obtain a positive sample set which comprises a plurality of positive samples; the classifier conformation process comprises the steps of obtaining sub-classifiers corresponding to all the positive samples through combining negative samples and misrecognition samples, and further obtaining required classifiers according to sets of all classifiers. Compared with the prior art, the method has the advantages of higher detection rate and higher capture rate.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for constructing a classifier for object detection and an object detection method. Background technique [0002] Target detection has always been a popular research direction in the field of computer vision. It is the most basic component of computer vision tasks. Its scientific research value lies in providing more advanced tasks in computer vision (such as target recognition, content analysis, artificial intelligence, etc. ) to provide basic research and technical support. In addition, target detection itself has good commercial application value, for example, most digital cameras are equipped with face detection systems. [0003] The detection method based on static images is one of the most commonly used methods in target detection methods. However, the existing object detection methods based on static images need to collect a large amount of training sampl...
