“…As the process of collecting image will be affected by light and noise and other factors, it is required that these images should be preprocessed such as de-noising before edge detection and pattern recognition of images. We used MATLAB [3][4] to preprocess and analyze original images in this paper.Image preprocessing focuses on image enhancement, image smoothing and image sharpening. Firstly strengthen the contrast of the original image and transform the original image into gray, which is shown in Figure 7, and then use linear variation to adjust their gray value.…”
