Problems solved by technology

The disadvantage of the above method is that all possible face positions and face sizes are exhaustively detected through traversal, and the processing efficiency is low, so it is very time-consuming, especially on embedded devices with limited hardware resources, which have stricter algorithm performance requirements. requirements

Abstract

The invention belongs to the technical field of human face detection, and particularly relates to a human face detecting method and device based on selective searching. The human face detecting method based on selective searching comprises the following steps: extracting human face features according to positive and negative sample sets of a human face, and training to obtain a human face classifier; dividing a to-be-detected image on the basis of selective searching to obtain a to-be-detected region set; expanding a to-be-detected region set according to preset parameters; detecting the to-be-detected region set by using the human face classifier to obtain a human face region set; and filtering out overlapped human faces to obtain a final human face region set. By the technical scheme, the to-be-detected image is divided, characteristics of the to-be-detected image are judged, regions which are human faces possibly are screened out to filter out meaningless regions, and the human face detecting efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of face detection, and in particular relates to a selective search-based face detection method and device. Background technique [0002] Face detection is to judge whether there is a human face in an image or a sequence of images (such as video), and if so, return information such as the size and position of the human face. At present, face detection technology has been widely used in various video surveillance places, among which face classifier is the most commonly used technical means, which refers to the algorithm for classifying faces and non-faces, and divides a certain area of ​​the image The input classifier is checked to determine whether it contains a human face. Different face detection technologies have different classifier training methods. [0003] In practical applications, because the face may appear in any position of the image with any size, it is necessary to detect each area of ​​the ima...
