摘要:
双稳系统中的不稳定点对图像增强起到了决定性的作用,使其充当了一个阈值的角色,在一定条件下,使得不稳定的点(也就是阈值)趋于稳定的点,以实现图像增强。本文研究了一类双稳系统,分析了该系统的线性稳定性,利用该性质,在特殊的时间点下,通过初值遍历每一个像素值,实现了图像直方图均衡化,达到了图像增强较好的效果。The unstable point in the bistable system plays a decisive role and acts as a threshold in image enhancement. Under certain conditions, let the unstable point (that is, the threshold) tend to a stable point in order to achieve the image enhancement. In this paper, a class of bistable systems is studied and the linear stability of the system is analyzed. By using this property, the image histogram equalization is realized by traversing each pixel value at the special time point. Better results.
