Research Of High-speed Image Transmission And Processing Technology Based On FPGA

With the increasingly widespread application of video image transmission and processing, the demand of image transmission speed and image quality has been getting higher, and the design of image transmission and proccessing system has been getting more complex. High speed image transmission and proccessing system have been bottleneck of image communication field.For the problems above-mentioned, this paper study high speed image data transmission and processing technology based FPGA, which has been concerned generally more and more. This design is based on FPGA control module as the core, achieving the video image data acquisition, caching, processing and control of communication between the various modules. This focus is on cleaning and purification in the process of high-speed video image transmission , that is digital filter de-noising, has been studied. Based on a brief analysis of some common image filtering denoising algorithm, combine characteristics and requirements of image denoising filter algorithm implemented by FPGA hardware. Propose an adaptive median filter algorithm based on the mean operation, then simulate function and analyse the result.
