[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0034] Glossary:
[0035] The two-dimensional Gabor filter is a filter that can better simulate the visual stimulus response of simple cells in the human visual system;
[0036] LBP (Local Binary Pattern) performs binary encoding by comparing the pixel value of the center and the neighborhood, which can appropriately increase or decrease the pixel value change under a small displacement, and is not sensitive to parallel lighting. . As a feature encoding tool, LBP has been widely used in face recognition feature extraction;
[0037] AdaBoost (Adaptive Boosting) is an adaptive boosting machine learning algorithm. AdaBoost can continuously adjust the sample weight through its own iteration, and integrate multiple weak classifiers into a strong classifier ...
