[0078] Taking the video face recognition method based on Adaboost and feature fusion as an example, the present invention will be further described in detail in conjunction with the accompanying drawings. The method specifically includes the following steps.
[0079] S1: Preprocessing of low-light face images based on fuzzy theory.
[0080] The image preprocessing in the present invention is to convert the image color space from RGB closely related to the color channel to HSV space and improve the brightness of the low-illuminance image by using the non-linear function.
[0081] S1.1HSV color space transformation.
[0082] At present, most of the images taken by camera equipment are RGB images. RGB images are obtained by weighting the three color components of red (R), green (G), and blue (B) to obtain various colors, but they are easily affected by light changes. Influence, and there is a high correlation between the RGB three primary color components, changing the color inf...
