Embodiment Construction

[0022] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific processes are provided, but the protection scope of the present invention is not limited to the following Example.

[0023] The whole implementation process of this embodiment is as follows:

[0024] 1. In the face bank (this face bank contains the face images of different postures of 2270 people. Each person includes the face images of 9 poses, as shown in Figure 1, Figures a, b, c, d, e , f, g, h, i these 9 face images are respectively -90°, -60°, -45°, -30°, 0°, 30°, 45°, 60°, 90°. The images in the face library can be divided into 9 categories according to their different postures, each category has 2270 images, and the images in each category have the same posture.) The face area is detected in th...

Description

technical field [0001] The invention relates to a method in the technical field of image recognition, in particular to a method for face gesture recognition using a restricted Boltzmann machine neural network. Background technique [0002] With the strengthening of global security awareness, human beings have higher and higher requirements for biometric identification technology, and among many biometric identification technologies, face recognition is the most feasible. However, the traditional two-dimensional face recognition is affected by factors such as illumination and posture, which cannot meet the requirements of practical applications. Therefore, it is a trend to expand from two-dimensional face recognition to three-dimensional face recognition, because three-dimensional space can provide more information for face recognition. However, this expansion from two-dimensional recognition to three-dimensional recognition also brings new problems, that is, how to estimate...
