Impact and Analysis of Improved Bilateral Filter on TEM Images

Garima Goyal

Abstract: TEM images are rapidly gaining prominence in various sectors like life sciences; pathology; medical science; semiconductors; forensics; etc. Hence; there is a critical need to know the effect of existing image restoration and enhancement techniques available for TEM images. This paper primarily focuses on denoising Bilateral Filter. The simulation is carried on greyscale and colored images separately. To do so different types of noise (Gaussian Noise; Salt & Pepper Noise; Salt & Pepper Noise & Poisson Noise) varying from 1 % to 9 % is incorporated into image. Each degraded image is denoised by filters.
