[0067] According to the method of the present invention, at first utilize Matlab or C language to write the training model of stack type self-encoder; Then import the training sample that gathers and train stack type self-encoder parameter; Then extract gradient direction histogram feature to the image that gathers, As the source data, it is input into the trained stacked autoencoder for processing; the estimated head pose is obtained. The method of the present invention can be used in the problem of head pose estimation in natural scenes.
[0068] A head pose estimation method based on stacked autoencoder, comprising the following steps:
[0069] Step 1: Collect N head depth images containing different poses, and record the head pitch, yaw, and rotation angles corresponding to each of the N images according to the position of the camera when collecting each image, and obtain the head pose vector The first dimension of represents the pitch angle, the second dimension represe...
