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… (More)
The images taken from an optical electronic microscope often contain data corrupted by noise, and the subject under study is normally blur due to improper focusing during image acquisition. Thus, in this paper, we propose the use of toboggan contrast enhancement method to solve this problem. First, the noise level in the image is reduced by using Gaussian… (More)
A simple contrast enhancement method based on histogram manipulation is presented. The method is based on histogram equalization and histogram stretching. The proposed method successfully enhances the microscopic image without over amplifying the noise level.
