A Hybrid Edge Detection Algorithm for Salt - and - Pepper Noise
This paper presents a hybrid edge detection algorithm in situations where the image is corrupted by Saltand-Pepper noise. Edge detection is an important preprocessing step in image analysis. Successful results of image analysis extremely depend on edge detection. Up to now several edge detection methods have been developed such as Roberts, Prewitt, Sobel, Zero-crossing, Canny, etc. But, they ar...
متن کاملIterative Removing Salt and Pepper Noise based on Neighbourhood Information
Denoising images is a classical problem in low-level computer vision. In this paper, we propose an algorithm which can remove iteratively salt and pepper noise based on neighbourhood while preserving details. First, we compute the probability of different window without free noise pixel by noise ratio, and then determine the size of window. After that the corrupted pixel is replaced by the weig...
متن کاملA Salt and Pepper Noise Removal and Restoration Refinement Algorithm
Noise removal is an important task inside the image processing area. In this paper, an algorithm for reducing salt and pepper noise and improving the restoration quality through refinement is presented. This algorithm proposes a double screen. As a first step, the algorithm computes an estimation of the denoised image by using an adaptive median filter. Then, the Non-Local Means algorithm is us...
متن کاملA Review Paper on Novel Approach for Removing Salt-And-Pepper Noise Using Trimmed Median Filter
we know that when we transmit data from transmitter to receiver definitely various types of noises added automatically to our main data and it’s very tough task at receiver side to get exact data whatever be transmitted from transmitter side. In this review paper our focus is to remove salt and pepper noise from contaminated image. Therefore we studied various research paper and finally we came...
متن کاملRemoving Salt-And-Pepper Noise from Digital Image Using Unsymmetric Trimmed Median Filter
Every digital image has a two-dimensional mathematical representation of the digital image. Digital image is made out of pixels i.e. picture component. Every pixel speaks to the dark level for highly contrasting photographs at a solitary point in the image, so a pixel can be spoken to by a small speck of particular shading. Image restoration is the process of restoring degraded images which can...
