Enhancement of Color Microscopic Images Using Toboggan Method

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 filter. Gaussian filtering results more blur edges. Thus, toboggan contrast enhancement is applied to restore the edges. Experimental result, from an image of algae taken by an optical microscope, shows that toboggan contrast enhancement successfully sharpen the image.
