An Iterative Unsymmetrical Trimmed Midpoint-median Filter for Removal of High Density Salt and Pepper Noise
An Iterative Unsymmetrical Trimmed Midpoint-Median Filter for Removal of High Density Salt and Pepper Noise in gray scale images is presented in this paper. This efficient filtering technique is implemented in two phases. In the first phase, the proposed midpoint median filter is applied to the noisy pixels iteratively two times iteratively. In the second phase, the Modified Decision based Mean...
متن کاملRemoval of High Density Salt & Pepper Noise Through Super Mean Filter for Natural Images
A super-mean filter (SUMF) is proposed to remove high density salt & pepper noise from digital images. The proposed filter works in two stages, in the first stage the noisy pixels are detected and in the second stage each noisy pixel is replaced by the mean value of noise free pixel of 2×2 matrix. Extensive simulation and experimental results shows that the proposed filter works well consistent...
متن کاملHigh Density Salt and Pepper Noise Removal in Images using Improved Adaptive Statistics Estimation Filter
In this paper a Non-linear Adaptive Statistics Estimation Filter to remove high density Salt and Pepper noise is presented. The algorithm detects the pixel corrupted by salt and pepper noise and replaces them with a value estimated using proposed algorithm. The algorithm detects the corrupted pixel at the initial stage itself. The performance of proposed algorithm is compared with various filte...
متن کاملIterative Switching Filter for High Density Noise Removal
This paper proposes an efficient filter for the restoration of images that are corrupted by high density of impulse noise. In this method an iterative switching filter is used that switches between two cases depending on the noise percentage in the input image. For low noise percentage it searches for the noise-free pixels within a small neighborhood. The noisy-pixel is then replaced with the a...
متن کاملA New Switching-Based Median Filtering Scheme and Algorithm for Removal of High-Density Salt and Pepper Noise in Images
A new switching-based median filtering scheme for restoration of images that are highly corrupted by salt and pepper noise is proposed. An algorithm based on the scheme is developed. The new scheme introduces the concept of substitution of noisy pixels by linear prediction prior to estimation. A novel simplified linear predictor is developed for this purpose. The objective of the scheme and alg...
