Myself BLACK,doing my Engineering final year in PSP college.For my final year project i am working Medical image processing field.Now i want ideas regarding the article Non local means speckle filtering of ultrasound images using Bayesian framework.I have attached the abstract of the project.

Abstract In image processing, restoration is expected to improve
the qualitative inspection of the image and the performance
of quantitative image analysis techniques. In this paper, an adaptation
of the nonlocal (NL)-means filter is proposed for ....etc

A new fuzzy filter is presented for the reduction of noise of damaged images with additive noise. The filter consists of two stages. The first step calculates a diffuse derivative for eight different directions. The second stage uses these fuzzy derivatives to perform diffuse smoothing by weighting the contributions of neighboring pixel values. Both stages are based on fuzzy rules that make use of membership functions. The filter can be applied iteratively to effectively reduce heavy noise. In particular, the form of ....etc

Abstract

The quality of the ultrasound medical images is usually degraded by two important problems - the transducer influence and the speckle noise. To remove the multiplicative speckle noise, in this paper it is presented a method based on a blind, time-domain, deconvolution algorithm. The proposed approach uses the envelope of the acquired radio-frequency signals for the numerical implementation. It is a two steps blind deconvolution, where firstly, the point spread function is automatically estim ....etc

The Electrocardiogram (ECG) is a valuable signal recording the heart's electrical activity. The filtering quality of ECG signals directly affects the medical diagnosis. Since wavelet analysis can provide both time and frequency information, many nonlinear thresholding methods based on wavelet transform denoising have been applied to the noise reduction of ECG signals. However, most of these threshold shrinkage functions cannot adapt to different signals due to the fixed transition curve of threshold. Therefore, a novel genetic optimized wavelet ....etc
