[0071] The present invention will be further described below in conjunction with the accompanying drawings.
[0072] Such as figure 1 , 2 As shown, a pedestrian re-identification method based on transfer learning, including the following steps:
[0073] Step 1: Use the Retinex algorithm to preprocess the original images in the dataset;
[0074] The original pedestrian image is preprocessed by the multi-scale Retinex color image enhancement algorithm:
[0075] I(x,y)=L(x,y)*R(x,y) (1)
[0076] In the formula, I(x,y) represents the original image, L(x,y) represents the illumination component of the ambient light; R(x,y) represents the reflection component of the target object carrying image detail information; for an original image I(x, y), the corresponding R(x, y) is calculated by the retinex algorithm, then R(x, y) is the enhanced image; the processed image can greatly alleviate the influence of light and make the image closer to the original color .
[0077] Step 2: Ex...
