Implementation of PPM Image Processing and Median Filtering

An improved recursive median filtering scheme for image processing

In a recent publication, it was shown that median filtering is an optimization process in which a two-term cost function is minimized. Based on this functional optimization property of the median filtering process, a new approach for designing the recursive median filter for image processing applications is introduced in this paper. We prove that the new approach is guaranteed to converge to ro...

Medical Image Enhancement Techniques by Bottom Hat and Median Filtering

This paper presents an efficient method for medical 2-D image enhancement technique using median and bottom hat filtering, that can also be used in image processing such as medical image reconstruction, image smoothing, feature extraction and image analysis. We present a comparison of these filters using the medical images. After filtering also the input image or actual image have some noise th...

Noise Removal in Image Processing using Median, Adaptive Median and Proposed Median Filter and Respective Image Quality Comparison

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...
