代码说明：

在图像处理中,图像增强技术对于提高图像的质量起着重要的作用"它通过有选择地强调图像中某些信息而抑制掉另一些信息,以改善图像的视觉效果,将原图像转换成一种更适合于人眼观察和计算机进行分析处理的形式"本文着重对图像增强方法中的灰度变换!直方图均衡化!模糊增强进行了深入的研究,针对增强过程中遇到的一些问题,提出了相应的解决方法"对于分段线性变换方法中如何划分灰度区间进行变换这一关键问题,给出了基于区域分割的分段线性变换方法,加快了调整灰度区间的过程,提高了算法的执行效率"为了适应图像的局部亮度特性,给出了基于抛物线调整的直方图均衡化方法,可以调节图像的明暗程度,增强区域的对比度,同时给出了一种选

4000W无桥PFC闭环simulink模型
4000W无桥PFC闭环simulink模型，总体上电流很好的跟随了电压。就是电流上升阶段有点锯齿波，可以下载后自行调节2p2z补偿器(PID)参数。调节好后，一定告诉我（微信号：ds52014g8n12）。还由其他模型需要的加我,比如交错恒流buck 30V50A等等。普通PFC。都是闭环
