Abstract

The invention is applicable to the intelligent terminal and the image processing field and provides a multi-face detection method and device under a complex background. The multi-face detection method comprises steps of performing skin color segmentation on an original image to obtain a skin color detection image, performing skin color mask layer processing on the color detection image to obtain the image after the skin color mask layer processing, and performing the human face characteristic verification on the image after the skin color mask layer processing to obtain the human face detection result image. The technical scheme is good in detection speed and low in misjudgment rate.

Description

technical field [0001] The invention belongs to the field of intelligent terminals and image processing, and in particular relates to a multi-face detection method and device under complex backgrounds. Background technique [0002] In the current field of face image information processing, there are many research directions such as face recognition, face tracking, pose estimation, expression recognition, etc. However, all these research directions involve a problem of face identification and positioning, namely It is necessary to know the position and size of the face in the image - face detection. Therefore, for a complete and automatic face information analysis system, a face detection algorithm is essential. [0003] Face detection refers to the process of determining whether there is a human face in the input image, and if so, determining its position and size. At present, face detection methods can be roughly divided into two categories: knowledge-based methods and st...
