A HYBRID TECHNIQUE FOR MEDICAL IMAGE DENOISING BASED ON HISTOGRAM EQUALIZATION USING WAVELET AND CURVELET TRANSFORMS

Abstract

In general all the binary images has some proportion of noise while we acquiring and transmitting the images. Particularly, medical images need to be more visualized due to their importance which simplifies the diagnosis and treatment. Medical images have composite type of additive noise depends on the gadgets that we avail them. So it is imperative assignment to get rid of noise from medical images exclusively in MRI, CT, SPECT, and Digital Mammogram and Ultrasound images. Selection of relevant mask is a resilient assignment. Here we come up with an approach that using various transforms such as Wavelet and Curvelet for denoising the medical images based on equalization of Histogram. The recommended technique is similar for various noisy images and it is also given more significant usage to all medical experts. The overall performance is evaluated in details of MSE (Mean Square Error) and PSNR (Peak Signal to Noise Ratio). This will show off the noise removal in medical imaging. Thus recommended method clearly surpass all the preceding approaches in medical image denoising related to perceptible performance measure , visual high quality of the photographs.

ECG DE-NOISING BY USING JAG-WAVELET FILTER FOR HEARTBEAT NOISE SIGNALS

Abstract

The electrocardiogram approach of recording bioelectric currents generated via the center premiums which is useful for diagnosing plenty of cardiac diseases. The point’s removal and de-noising of ECG are extremely realistic in cardiology. Electrocardiogram is a non-stationary sign and it\'s used for the primary analysis of cardiac abnormalities like arrhythmia, myocardial infarction and conduction defects. However, the ECG sign most of the time contaminated by using distinctive noises. The ECG sign must be de-noised to eliminate all the noises corresponding to Additive White Gaussian noise and speckle noises. This paper deals with the analysis of ECG signal de-noising utilizing Jag-Wavelet (Joint Analysis Gain) change into. Extraordinary ECG indicators from MIT/BIH arrhythmia database are used with introduced Gaussian noise and speckle noises. Gentle thresholding procedure is employed within the sign and the outcomes have been evaluated using MATLAB. The proposed approach to search out highest features applying wavelet established multi-stage decompositions, and calculated each MSE-utilizing imply square Error and output SNR signal to noise ratio. The skills of the expanded thresholding de-noising method are that it retains both the geometrical characteristics of the long-established ECG sign and variations within the amplitudes of more than a few ECG waveforms simply. The experimental results point out that the proposed approach is best than existing traditional filter techniques within the features of final geometrical characteristics of ECG sign and in development of sign-to-noise ratio (SNR).

A COMPREHENSIVE STUDY AND APPROACH ON DISSIMILAR MATERIALS USED IN WELDING PROCESS

Abstract

Selection of welding parameters is very important to increase the weld strength. Friction stir welding parameters affect the weld strength of aluminum alloy and EN8, such as high strength welding products. The procedure involved the development of a series of tests and observation of the parameters that will be controlled during the welding process. After the tests were performed, the samples were prepared for chemical attack, which allowed observation of the penetration, weld area, and dilution. After that, mathematical models were developed that correlate the controllable welding parameters with the aforementioned bead parameters.

STUDY ON PREPARATION OF BIO-DIESEL BLENDS WITH KARANJA OIL AS A ALTERNATIVE FUEL

Abstract

Biodiesel has obtained from vegetable oils that have been considered as a promising alternate fuel. Karanja oil is non edible in nature and is available abundantly in India. An experimental investigation was made to evaluate the performance, emission and combustion characteristics of a diesel engine using different blends of methyl ester of karanja with mineral diesel. The experimental results data were analyzed by using 20% blends of Karanja with 80% diesel by volume and 100% preheated karanja for various parameters like specific fuel consumption, brake thermal efficiency and emission of exhaust gas like CO, CO2, HC and NOx. The brake thermal efficiency and mechanical efficiency were better than mineral diesel for some specific blending ratios under certain loads. The emission characteristics were also studied and levels of carbon dioxide, carbon monoxide, nitric oxide and hydrocarbons were found to be higher than pure diesel. The emissions of smoke, hydro carbon and nitrogen oxides of dual biodiesel blends were higher than that of diesel. But the exhaust gas temperature for dual biodiesel blends was lower than diesel.

NODE COLLAPSE DETECTION IN MOBILE WIRELESS NETWORKS: A STUDY OF FEASIBILITY

Abstract

Detecting node failures in mobile wi-fi networks could be very challenging because the network topology may be noticeably dynamic, the community might not be usually connected, and the sources are constrained. on this paper, we take a probabilistic method and advocate two node failure detection schemes that systematically combine localized monitoring, area estimation and node collaboration. sizeable simulation results in each connected and disconnected networks show that our schemes attain high failure detection fees (close to an higher bound) and occasional false nice fees and incur low communique overhead. in comparison to processes that use centralized monitoring, our method has up to eighty percent lower verbal exchange overhead, and simplest slightly lower detection prices and barely better false superb rates. further, our technique has the advantage that it\'s far relevant to both linked and disconnected networks while centralized tracking is simplest applicable to connected networks. in comparison to other techniques that use localized tracking, our method has comparable failure detection quotes, up to 57 percentage decrease verbal exchange overhead and lots decrease fake high-quality fees (e.g., zero.01 versus 0.27 in some settings).
