| Abstract: | In view of the currentSdigital image processingSspeedSproblems,the method is proposed for implementing Laplace edge detection on the FPGA chip-xc7z020-1clg484 based on System Generator software, The system is composed of the buffer module, the edge detection module and the image binaryzation module and it is succeed in emulating and realizing by Vivado software. Takin a 37KB image, assuming the clock driver source is 100MHz, the system needs 0.738228ms to complete the process and can process 1250 images per second. It solves the speed problems and provides a new method of realizing the complex algorithm on FPGA. |
