Digital Image Processing System Based on FPGA

This paper proposes a digital image processing system that uses FPGA to process color images into black and white images and outlines the edge lines of objects. And the digital image processing system is used to recognize printed numbers through feature discrimination. The digital image processing system built by FPGA has the characteristics of simple structure, high real-time performance, low-frequency requirement, and high integration. This is not only suitable for high-speed real-time systems, but also saves hardware resources to a great extent, and significantly reduces design costs. The realization of this paper is to capture the RGB565 format image by the camera and convert it into the YCbCr format image, and then project the image in the horizontal and vertical directions and then perform feature discrimination on the captured numbers. Finally, the result is output through the digital tube.
