Algorithms Research And Hardware Design Of Image Processing Based On FPGA

The paper studies about the realization of the image collection, image processing algorithms .the function of the image collection part is to convert the analog data from the analog camera into the digital data, and to pick up the useful data from the data flow, and finally to incorporate the odd and even field into a frame and save it to a memory after the appropriate cut .The function produced by the daital data flow is collected by the SAA7113 chip, however, FPGA initializes and controls the SAA7113 chip ,and manipulates the data as well .Taking account of some factors such as real time character complexity of algorithim, the image processing algorithm part chose two algorithms to realize, they are median filter and edge inspection.The full design of each module are synthesized and simulated on QUARTUS II of Altera Corp and Modelsim .The result of synthesis and simulation indicate that the design of image processing algorithim based of FPGA not only achive a good processed result and get a high frequency, but also it can give a better performance of speed then using software and fit for real-time image processing .
