摘要
文章研究了直方图均衡化算法、直方图拉升算法、暗通道算法的FPGA实现,比较了不同算法所消耗的硬件资源和实时去雾效果。并对不同算法的硬件实现过程进行一定的改进,以利于FPGA实现。实验发现,相关算法在cyclone芯片EP4CE30F28C8上实现,在实验条件640*480@60Hz,视频实时去雾无卡顿,并达到一定的去雾效果。
This paper studies the FPGA implementation of histogram equalization algorithm,histogram pull-up algorithm,and dark channel algorithm,and compares the hardware resources consumed by difierent algorithms and the real-time defogging effect.And certain improvements are made to the hardware implementation process of different algorithms to fecilitate FPGA implementation.It is found that the relevant algorithms are implemented on cyclone chip EP4CE30F28C&and the video is defbgged in real time without lag and achieves certain defogging effect under the experimental condition of 640*480@60 Hz.
