Image data storage method based on FPGA

In the process of image acquisition and transmission, noise usually occurs, which reduces the image quality and affects the subsequent processing. Therefore, it is necessary to do some image filtering, image enhancement and other preprocessing. In order to improve the image quality, the image is usually filtered to remove the noise, which can not only […]
