Abstract

The invention belongs to the field of intelligent recording and broadcasting systems, and relates to a method for detecting and locating standing human faces in an intelligent recording and broadcasting system. value, and then perform morphological operations on the image, mark the active area and retain it with the smallest circumscribed rectangle, and perform light compensation on it, and then filter out the interfering active area through skin color detection, and classify it according to the proportion of the face area Screening and exclusion of skin-colored but no-face areas, and finally data analysis based on the processed data to mark faces. This method is ingenious in design, simple in detection principle, easy to operate and use, and can complete standing with only one camera. Face detection and positioning, low equipment requirements, high accuracy of detection results, friendly application environment, and broad market prospects.
