Impulse Noise Removal in Digital Images
This paper introduces the concept of image fusion of filtered noisy images for impulse noise reduction. Image fusion is the process of combining two or more images into a single image while retaining the important features of each image. Multiple image fusion is an important technique used in military, remote sensing and medical applications. Five different filtering algorithms are used individ...
متن کاملImpulse Noise removal in Digital Images
In this paper, we introduce a new class of filter, the modified spatial median filter (MSMF) for the removal of impulse noise in digital images. The proposed filter is compared with four different filtering algorithms based on their ability to reconstruct noise-affected images. In-order to better appraise the noise cancellation behavior of our filter from the point of view of human perception, ...
متن کاملImpulse noise removal in highly corrupted color images
We present in this paper a novel and efficient technique for the restoration of color images which are highly corrupted with impulse noise. This is a detectionestimation based approach in which outliers are first detected using a Teager-like operator followed by a locally adaptive threshold. Center pixels whose “energy” exceeds some threshold are replaced with the local marginal median. Simulat...
متن کاملAdaptive Real-Time Removal of Impulse Noise in Medical Images
Noise is an important factor that degrades the quality of medical images. Impulse noise is a common noise, which is caused by malfunctioning of sensor elements or errors in the transmission of images. In medical images due to presence of white foreground and black background, many pixels have intensities similar to impulse noise and distinction between noisy and regular pixels is difficult. In ...
متن کاملImpulse Noise Removal in Images Using Morphological Set Notation
These papers propose a novel method for noise removal in the images. The impulsive noise takes gray level values from the image as minimum or maximum from the dynamic gray level range. In this paper Set notations are proposed to eliminate the noise pixels corrupted by low and high gray level values. The method also adopt median and is compared with obtained Set notation values from local neighb...
