Abstract

Disclosed is a processing device (102) and method (200) for faster face detection. a method (200) for detecting a presence of at least one face in at least one image is disclosed. The method (200) comprises of creating (202) an image patch map based on a plurality of face patches identified for at least one window in said in at least one image; estimating (204) a bounding box; and searching (206) within said bounding box to detect presence of said at least one face in said at least one image. The present invention discloses use of any classifier which works on top of any feature representation to identify face patches and then using a masking system to identify bounding boxes. The present invention is applicable in the area of but not limited to handheld terminals/devices, HD video Surveillance, and camera auto-focus based on face detection.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a face detection processing method and a processing device for face detection. Background technique [0002] Face detection is an important research direction in the field of computer vision, because it has a wide range of potential applications, such as video surveillance, human-computer interaction, face recognition, security authentication, face image database management, etc. Face detection is to determine whether any faces are present within a given image, and if one or more faces are present, return the position and extent of each face. [0003] HD cameras are an affordable commodity today and are widely used in all types of applications such as video surveillance. Video analytics in the form of face detection must match the high-resolution output of the camera, so the performance of these algorithms is critical to the overall performance of the analytics. [0004] Face de...
