Abstract

The invention discloses a face key point detecting method and device. The method comprises the steps that a face image to be detected is obtained; initial key points of N specific organs are determined in the face image by using a first face key point detecting algorithm, wherein N is larger than or equal to 1; the region, where each specific organ in the N specific organs is located, in the face image is determined with the corresponding initial key point as reference; a final key point of each specific organ in the N specific organs is determined in the region, where the specific region is located, in the face image by using a second face key point detecting algorithm. By means of the method, the number of the searching regions detected through the second face key point detecting algorithm can be reduced, and the detecting efficiency of face key points can be improved obviously.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for detecting facial key points. Background technique [0002] Facial key point detection is an extremely important step in face image analysis, and it is also an indispensable basic step in subsequent face analysis. At present, face analysis technology is not only applied on the computer side, but also gradually moving towards the mobile side, which puts forward higher requirements for the speed, accuracy and stability of facial key point detection. [0003] In the current method, in the facial key point detection algorithm that ensures the accuracy and stability of detecting facial key points, and adapts to complex environments and various face postures, the detection speed is relatively slow, and the algorithm complexity is relatively high. At the same time, it will occupy most of the resources of the device processor, especially when the facial key point d...
