Abstract

The invention discloses an image preprocessing method and system for a wireless scanning pen, wherein the image preprocessing method for the wireless scanning pen includes: receiving an original image acquired and sent by the wireless scanning pen, performing median filtering on the original image, and extracting grayscale values. The grayscale image is processed by the histogram algorithm to obtain a grayscale histogram; the grayscale image is subjected to binarization processing; the morphological closing operation is performed on the binarized image to obtain The final image after image preprocessing. The image preprocessing method and system of the wireless scanning pen of the present invention solve the problem of defects in the acquired original image of the wireless scanning pen, and restore the original image to a complete and clear image, so as to facilitate subsequent image recognition.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image preprocessing method and system for a wireless scanning pen. Background technique [0002] Image preprocessing technology is the most basic part of image engineering, and it is the most important and critical step in image processing and analysis, because images will be damaged by certain programs and polluted by various noises during transmission and storage. There are biases and errors in the data. Image preprocessing can provide an important foundation for subsequent image feature extraction and image analysis and understanding. [0003] In the actual application process, the original image of the wireless scanning pen obtained by the server is defective, and there are many factors that affect the quality of the original image. The dark part is darker; impulsive noise is caused by the CMOS (camera) in the process of image acquisition a...
