Embodiment 1
[0040] combine figure 1 As shown, a kind of vehicle logo recognition method based on feature enhancement of the present invention specifically comprises the following steps:
[0041] 1) Preprocessing the car logo image
[0042] Input the car logo image and perform preprocessing to obtain the processed image; specifically, the input car logo image is the car logo image captured by various camera equipment; the specific process of preprocessing the car logo image is: firstly, the car logo image Perform normalization processing to obtain an image of a standard size, and then grayscale the image to obtain a processed image; where the standard size of the image is w0×h0, w0 represents the width of the image, h0 represents the height of the image, the w0 and h0 is the pixel value. It is worth noting that since the different sizes of the input vehicle logo images will affect the feature extraction, the vehicle logo images are first reduced or enlarged to a standard size. The standa...
