Embodiment Construction
[0065] 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 with reference to the accompanying drawings and examples.
[0066] Embodiments of the present invention firstly provide a method for locating key feature points. The method is divided into four steps: face detection, face area edge extraction, candidate feature point extraction, and feature point matching. The specific process is as follows: figure 1 shown, including:
[0067] Step 101: Perform face detection on the target image, and determine the face area in the target image as the image to be aligned;
[0068] Wherein, in this step, the target image is the input image that needs to locate key feature points, and the face detection of the target image is the process of detecting the target image and judging whether the image contains a human face area , various face detection methods in the prior art can be u...
