HIERARCHICAL FACE RECOGNITION TRAINING METHOD AND HIERARCHICAL FACE RECOGNITION METHOD THEREOF
First Claim
1. A hierarchical training method for a face recognition, using a computer device to perform a face feature training of sub-image detectors at each level on a plurality of training samples, the method comprising:
- obtaining the training samples;
performing a training measure, subdividing the training samples into a plurality of sub-image categories according to a plurality of angle intervals, and performing the training of a plurality of face features on a corresponding sub-image detector of each of the sub-image categories;
repeatedly performing the training measure on each of the sub-image categories, so as to generate sub-image categories at a sub-level of the sub-image categories until a subdivision condition is satisfied.

Abstract
A hierarchical face recognition training method and a hierarchical face recognition method thereof for performing a face feature recognition on an image under detection. The method includes a training process and a recognition process. The recognition method includes the steps. A plurality of training samples is obtained. The training samples are subdivided into a plurality of sub-image categories according to a plurality of angle intervals, and the training of a plurality of face features performs on a corresponding sub-image detector of each of the sub-image categories. The training measures performed repeatedly to generate sub-image categories at a sub-level of the sub-image categories. The training method includes the steps. An image under detection is loaded. A similarity of each of sub-image detectors compares according to the image under detection, and the sub-image detector having the highest similarity is selected. The face recognition measures performed repeatedly on the selected sub-image detector.
