This paper describes a new filter for impulse noise reduction in colour images which is aimed at improving the noise reduction capability of the classical vector median filter. The filter is inspired by the application of a vector marginal median filtering process over a selected group of pixels in each filtering window. This selection, which is based on the vector median, along with the applic...

Abstract: In this paper, image-denoising proposed median filter is implemented for denoising of corrupted image and edge preservation. This method enhances the Peak Signal to Noise Ratio(PSNR) and perceives the original features of the images. This filter is compared with median and Adaptive median filter. The paper is organized as follows. Section II presents the introduction to image processi...

in this paper, a novel decision based median (dbm) filter for enhancing mr images has been proposed. the method is based on eliminating impulse noise from mr images. a median-based method to remove impulse noise from digital mr images has been developed. each pixel is leveled from black to white like gray-level. the method is adjusted in order to decide whether the median operation can be appli...

Lung cancer is a curable disease if detected early, and its mortality rate decreases with forwarding treatment measures. At first, an easy accurate way to detect by using image processing techniques on the cancer-affected images captured from patients. This paper proposes novel lung detection method. Firstly, adaptive median filter algorithm (AMF) applied preprocess those for improving quality ...

To extract the weak fault features hidden in strong background interference event of early failure rolling bearings, a two-stage based method is proposed. The broadband noise elimination ability an adaptive morphological filter (AMF) and superior capability frequency band selection (FBS) strategy for transient location identification are comprehensively utilized by proposed method. Firstly, AMF...

Digital images are often corrupted by different noises. These noises can be removed by designing an efficient filter. Based upon the specified operation the pixels are classified. Absolute Difference Based Progressive Switching Median Filter (ADBPSMF) outperforms all other filter for the removal of impulse noise from corrupted images. This filter performs two basic operations for efficient nois...
