Abstract
A method and a system for thermal infrared facial recognition are provided. The method includes: determining a thermal infrared facial image to be recognized; inputting the thermal infrared facial image to be recognized into a trained three-sense component extractor to position eyes, a nose, and a mouth of a face in the image, and to perform regional positioning of a left eye, a right eye, the nose, and the mouth, so as to constitute a corresponding key region group; performing affine transformation on the thermal infrared facial image to be recognized using a difference between a key region group of a standard face and the key region group of the face to be recognized; inputting a thermal infrared image after face alignment calibration into a trained facial feature extraction to extract corresponding facial features; and inputting the extracted facial features into a trained classifier to recognize information of an owner.
