IJSER © 2013 http://www.ijser.org Abstract — This paper presents the Wavelet based Image De-noising. The search for efficient image De-noising methods is still a valid challenge at the crossing of functional analysis and statistics using discrete wavelet transform. De-noising of stationary images corrupted by Gaussian noise using wavelet techniques is very effective because of its ability to ca...

The details of an image with noise may be restored by removing noise through a suitable image de-noising method. In this research, a new method of image de-noising based on using median filter (MF) in the wavelet domain is proposed and tested. Various types of wavelet transform filters are used in conjunction with median filter in experimenting with the proposed approach in order to obtain bett...

With the growth of the multimedia technology over the past decades, the demand for digital information has increased dramatically. This enormous demand poses difficulties for the current technology to handle. One approach to overcome this problem is to compress the information by removing the redundancies present in it. This is the lossy compression scheme that is often used to compress informa...

Analysis and interpretation of 2D gel images is a very important task in proteonomics study. The nonlinearties in the gel formation and image acquisition process leads to distortions, overlapped protein spots, saturated spots, faint spots, nonlinear intensity and uneven background in the gel images. As a result, pre-processing steps are important before image-analysis. De-noising is one of the ...

In this report, we give a probabilistic model for automatic change detection on airborne images taken with moving cameras. To ensure robustness, we adopt an unsupervised coarse matching instead of a precise image registration. The challenge of the proposed model is to eliminate the registration errors, noise and the parallax artifacts caused by the static objects having considerable height (bui...

i ntroduction: we studied and measured facial parameters of 160 students,aged 22-24 years attended at sahand university of technology in northwest of iran. mat erial and methods: in this paper, six linear and six angular facial parameters are measured. these parameters are measured in frontal and profile facial images. the measured values are the mean and standard deviation (sd) of distance bet...

background: glucantime ® is the first- line drug for the treatment of all forms of leishmaniasis. unfortunately, the prevalence of parasites becoming resistant to glucantime ® is increasing in several parts of the world including iran. as protein is the most important target for drugs in response to a variety of signals including drugs so, it seems expression protein patterns in sensitive and r...
