Abstract
Apparatus for vehicle driver recognition includes: a NIR LED illuminator, configured to emit NIR light in the vehicle; a NIR light sensing unit, configured to capture reflected NIR light; an image controlling and processing unit, configured to coordinate the NIR LED illuminator and the NIR light sensing unit, and analyze the reflected NIR light to generate an image; a face detector, configured to determine that a human face exists in the image, and identify a face region; a face feature extractor, configured to analyze the face region to extract a feature vector representing the face region; a face feature dictionary, configured to store existing feature vectors; a face retrieval system, configured to generate an identification result, indicating whether a similarity between the feature vector and any of the existing feature vectors is greater than a first threshold; and a user interface, configured to display the identification result.
