The design of real-time image denoising and filtering based on FPGA
Abstract: Image processing in the general computer and its software system applications have been a greater development, but because of the large amount of serial computing, power consumption and large size, so real-time and convenience is not too ideal. To this end, this paper designed a portable real-time image acquisition and image noise reduction as one of the hardware system. The system uses the analog camera and video decoder chip TW2867 as the image acquisition module, and then use the FPGA core module to deal with images, through the DDR3 storage and call data. Finally, select the VGA as the output mode. System using STM32F103 on the chip configuration. The test results show that the system has image acquisition and noise reduction function, and has the characteristics of low power consumption, easy to carry and high real-time performance.
