چکیده

This paper presents an evaluation of various unsharp masking techniques for enhancement of Electron Magnetic Resonance (EMR) images. Both the linear and non-linear unsharp masking techniques are tested for contrast enhancement of continuous wave EMR images. In vivo EMR renal images as well as leg-tumor images of a mouse are used as test images. Both visual appearance as well as Signal to Noise Ratio (SNR) are used as the metrics of evaluation. The results suggest that adaptive unsharp masking technique performs well for EMR image enhancement, compared to the other approaches.

Image Zooming using Non-linear Partial Differential Equation

The main issue in any image zooming techniques is to preserve the structure of the zoomed image. The zoomed image may suffer from the discontinuities in the soft regions and edges; it may contain artifacts, such as image blurring and blocky, and staircase effects. This paper presents a novel image zooming technique using Partial Differential Equations (PDEs). It combines a non-linear Fourth-ord...

A framework for contrast enhancement by dyadic wavelet analysis

This paper introduces a method for accomplishing mammographic feature analysis by mul-tiresolution representations of the dyadic wavelet transform. Our approach consists of the application of non-linear enhancing functions E(z) within levels of a multiresolution representation. We show that there exists a simple constraint for E(z) such that image enhancement is guaranteed. Furthermore, a simpl...

HSV-domain Enhancement of High-contrast Images - Power Laws and Unsharp Masking for Bounded and Circular Signals

We present techniques for performing luminance mapping and unsharp-masking-like processing on digital images; they are specifically designed for their application on bounded and on circular signals. We study the effect of gamma correction on contrast and develop an adaptive technique for luminance and contrast correction. We use the proposed tools for the enhancement of high contrast color images.

A Wavelet Based Generalized Unsharp Making Algorithm

In this paper we propose an improved unsharp masking algorithm. Contrast enhancement and image sharpness is required in many applications. Unsharp masking is a classical tool for sharpening an image. Unsharp masking algorithm is used for the exploratory data model as a unified framework. Proposed algorithms have three issues: 1) Contrast is increased and image is sharp by means of individual tr...
