Purpose One of the fundamental tasks in the field of image processing is image denoising. Images are often corrupted by different types of noise and the restoration of images degraded with random-valued impulse noise is still a challenging task. The

This paper proposes a fast switching based median–mean filter for high density salt and pepper noise in images. The extreme minimum value and extreme maximum value of the noisy image are used to identify the noise pixels. In the filtering stage, th

In this paper, a novel decision based adaptive median filter to remove blotches, scratches, streaks, stripes and random valued impulse noise in images is presented. The proposed method is a two stage algorithm. In the first stage the noise candidates

In this paper, a new nonlinear filter called detail preserving median based filter for removing salt and pepper noise and random valued impulse noise with edge and detail preservation is presented. The proposed method first detects the impulse pixel

In this paper a new algorithm is proposed to remove Gaussian noise with edge preservation. The function of the proposed algorithm is to first find the pixel values along the boundary of the filtering window and then calculate its variance. If this va

In this paper a new efficient algorithm to remove scratches, stripes and blotches with impulse noise in still images using robust estimation based filter is proposed. A new attempt is made to remove scratches, stripes and blotches that are artificial

A new switching-based trimmed median filter to remove high-density salt-and-pepper noise in digital images is proposed. Initially, a 3×3 sliding window is applied on each pixel in the noisy image. The minimum- and maximum-intensity values are trimme
