圖像預(yù)處理設(shè)計與實現(xiàn)
[Abstract]:Digital image processing, also known as computer image processing, plays an important role in the fields of resident life, industrial production, aerospace and so on. In order to remove some noise generated in the process of image transmission and digitization, and to reduce the irrelevant information of the image, so that the image can be better analyzed and understood. This paper first introduces the hardware construction of image preprocessing platform, and describes the hardware composition of platform processor, memory, power supply, reset and so on. The corner detection algorithm which can extract image features and simplify image data is studied. Several corner detection algorithms are analyzed and studied. An adaptive Harris corner detection algorithm is proposed to overcome the shortcomings of Harris corner detection algorithm. The correctness of the scheme is verified by Matlab, and the improved corner detection algorithm can extract corner information more effectively. Secondly, the DCT compression algorithm is studied, and an adaptive algorithm is proposed to overcome the shortcomings of the algorithm. The correctness of the scheme is verified by using Matlab. The improved algorithm can effectively improve the performance of the algorithm. Finally, we study a series of filtering algorithms that can be used in FPGA, such as median image filtering, minimum filtering, maximum filtering, morphological filtering, Gao Si filtering, Sobel edge detection filtering. These filtering methods can be effectively implemented on FPGA.
