Abstract

The invention relates to the field of image processing. An embodiment of the present invention provides a head posture estimation method and a machine-readable storage medium. The head posture estimation method comprises the following steps: acquiring a tricolor color image and a depth image to be subjected to the head posture estimation; extracting a face region from the three primary color images, and generating a face gray image corresponding to the three primary color images and a face depth image corresponding to the depth image based on the extracted face region; extracting a face contour image corresponding to the face gray image; and inputting the face gray image, the face contour image and the face depth image to a head pose estimation model to output a head pose estimation resultfrom the head pose estimation model. Thus, the head pose estimation based on a single face image can be realized, and high estimation accuracy and efficiency can be ensured.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a head pose estimation method and a machine-readable storage medium. Background technique [0002] Head pose estimation is the process of inferring a person's head deflection angle from digital or video images. Head pose estimation belongs to the subdivision field of face calibration and recognition, and is mainly used to assist related tasks such as the calibration of key points of the face and side face image recognition. [0003] In the process of face recognition, usually after the face is detected, before the pixel position of the key point on the image is automatically marked on the face, a more accurate orientation of the face (that is, the head pose) can be given. ), the key point calibration of the face will become simpler and more accurate. Specifically, in the face recognition problem, the comparative recognition of side faces and front faces has always been a...
