一种基于 FPGA 的彩色图像实时增强方法
Real-time color image enhancement method based on FPGA
摘要
Abstract
Color image contains rich detail information,and can apperceive the world intuitively.It makes our work and life more convenient.However,due to the impact of bad environment,it will cause to obtain a degraded image,such as the captured image is usually be blurred,the target is sub-merged.The existing color image enhancement methods are mainly post-processing approaches.It is difficult to achieve the real-time requirement for identification and tracking in practical engineering ap-plications.To solve this problem,an embedded real-time image enhancement processing system is de-signed based on FPGA.The system carries on the gray value stretch transformation to each color com-ponent of RGB color space and outputs real-time enhancement image.It not only increases the range of gray value to improve the visual effect of the human eyes,but also saves processing time to meet the real-time requirements of the project.It has been put into application in the actual project.The engi-neering results show that the system works stably,and can effectively solve the low contrast and insufficient light problem.关键词
