A NOVEL DENOISING TECHNIQUE BASED ON MORPHOLOGICAL METHODS
Min Bai, Sreedevi Jasthy · 2013
Abstract: The removal of impulse noise often brings about blurring which results in edges being distorted and poor quality. Therefore the necessity to preserve the edges and fine details during filtering is the challenge faced by researchers today. This paper proposes a Morphological approach for detecting and removing salt and pepper noise, Gaussian noise and Speckle noise. The noise detection is based on erosion and dilation. The results show that this method is good for noise reduction especially in high level noisy images.
