Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] figure 1 The flow of the face detection method provided by the embodiment of the present invention is shown.

[0024] In step S101, the face image is segmented to obtain the skin color region corresponding to the face.

[0025] In the specific implementation process, when the image is segmented, the HSV color space is first selected to segment the image. Since the skin color of the face has good clustering in the HSV space, it is convenient for subsequent skin color modeling. Afterwards, in the segmented area, the skin color area corresponding to the human face is obtained through the firs...

Abstract

The invention belongs to the technical field of image processing and discloses a mobile terminal as well as human face detection method and device thereof. The method comprises the following steps of: partitioning a human face image to acquire the corresponding skin-color areas of a human face; carrying out geometrical detection to the acquired skin-color areas to acquire an image contour of the human face image; calculating the size and the step length of a window for detecting the image contour and adjusting the size and the step length of a level classifier according to a calculating result; and confirming the acquired image contour according to the adjusted size and step length of the level classifier. The human face detection method provided in the invention can be conveniently used together with a hand-held terminal, and not only reduces the searching time, but also reduces the false recognition rate and is beneficial to the generalization of the hand-held terminal.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a mobile terminal and a face detection method and device thereof. Background technique [0002] In recent years, with the development of computer vision technology and the promotion of mobile multimedia business application requirements, the face detection and tracking technology for embedded applications has been greatly developed, such as mobile phone face recognition, mobile phone camera face special effects, human Application scenarios such as face replacement, mobile phone camera face focusing, and face recognition access control all need to detect specific face targets. The experience level of these applications is closely related to the performance of face detection methods. [0003] Researchers at home and abroad have proposed many effective face detection methods, which can be roughly summarized into two categories based on domestic and foreign liter...
