摘要

在本文中,我们改进了一种称为自适应平台直方图均衡化(SAPHE)的方法来增强光学显微镜获得的显微图像。首先,我们的方法自动确定平台阈值;基于直方图本身。然后,使用这个平台阈值,修改直方图的箱子。最后,基于改进后的直方图进行直方图均衡化。实验结果表明,与全局直方图均衡化相比,改进的SAPHE方法能够在不过度放大噪声的情况下增强显微图像。

Enhancement of Microscopic Images Using Modified Self-Adaptive Plateau Histogram Equalization
In this paper, we modified a method known as Self-Adaptive Plateau Histogram Equalization (SAPHE) to enhance microscopic images acquired using optical microscope. First, our method decides the plateau threshold value, automatically; based on the histogram itself. Then, using this plateau threshold, the bins of the histogram are modified. Finally, histogram equalization based on this modified histogram is carried out. Experimental results show that this modified SAPHE method is able to enhance the microscopic images without over amplifying the noise level, as compared with global histogram equalization.
