Medical Image Denoising and Enhancement using DTCWT and Wiener filter

Image denoising is the process to remove the noise from the image which contains noise. Wavelet transform technique is a unique mathematical manipulation framework used for medical image denoising and enhancement implementation. The wavelet techniques are effective to remove the noise due to their ability to capture the energy of a signal in a few energy transform values. A dual-tree complex wavelet transform is used to present the image enhancement process. The proposed technique has the cascaded structure of DTCWT used for generation of different frequency bands for analysis. In this paper, a denoising approach based on dual-tree complex wavelet and Wiener filter technique is used. The result has a better balance between smoothness and accuracy than the DWT and is less redundant than SWT. We used the SIM (Structural Similarity Index Measure) along with PSNR (Peak Signal to Noise Ratio) to assess the quality of denoised images.

Image Enhancement using DCTWT and Interpolation Techniques

As image enhancement is the main issue for biomedical images, this paper aims to present the methods using wavelets to enhance it. Digital image processing plays a vital role in today's new digital imaging devices. To perform the operation on the low-quality input images, frequency domain manipulations are widely used. Image enhancement is one of the types of processing in digital image processing domain. To perform this operation sophisticated wavelet transformation is used which has better enhancement as compared to their spatial domain counterpart. In the proposed paper, a novel technique for the biomedical image, general images up to certain MB enhancement using dual-tree complex wavelet transform is used. Dual-tree complex wavelet is a parallel combination of two discrete wavelet transform which has the property of shift invariance which results in lesser artifacts generated in output enhanced image. Interpolation is using for high precision in this paper B-spline interpolation give better results. To perform this operation and finding out the best possible transform among the available wavelet family. Proposed implementation has three transforms namely symlet, D'mayer, daubechies, and haar transform are used. The input image is first decomposed using wavelet transform to generate frequency bands, values of PSNR, Q-index and SSIM are calculated for study enhancement results.

Non-Market issues in WTO: With special reference to China

The Multilateral Trading System was created in the 1940`s with the GATT, containing clear objectives to liberalize and promote trade as an instrument of economic development. Aiming to become universal, the Multilateral Trading System gave support and incentives to both market and Non-Market Economies (NMEs) to participate in its activities. With the strengthening of the Cold War, however, NMEs left the negotiations leading to General Agreement on Trade and Tariffs (GATT).

A study on RCA as parialy replacement with natural aggregate

Recycle Concrete Aggregate has also been described as “the most revolutionary development in concrete construction for several decades”. It has proved to be beneficial from the point of economic, environmental benefits and Preservation of non-renewable recourses this thesis presents a study conducted on mechanical and durability properties of recycled aggregates concrete. The investigation covered concrete mixes at the water-cementitious material with a ratio of 0.4. Ordinary Portland cement of 43-grade was used in this study. The percentage of recycled aggregates that partially replaced natural aggregates by weight were 0%, 15%,30%, 45%, 60% and 75%. Concrete cubes and cylinders were cast and tested in laboratories. The optimum proportion of replacement was found by conducting tests on mechanical properties like Compressive strength test and Split tensile strength test. To assess the corrosion and durability characteristics of recycled concrete aggregates Acid and alkalinity resistance test were performed. The results show that the optimum replacement of recycled aggregates with natural aggregates was 45%. Up to 45% replacement, it is possible to gain the same strength as conventional concrete. Beyond 45% replacement the strength results following a decreasing trend.

Energy comparative analysis of diverse routing protocols in MANET for healthcare environment: Survey paper

Nowadays, wireless networks play a vital role in diverse filed due to a huge area of application. An ad-hoc network is a mull over as a fragmentation type of wireless network. MANET is a category of an ad-hoc network where nodes are high octane. The MANET is made up of a number of mobile nodes that can connect to each other over multi-hop wireless links on an ad-hoc basis. Adhoc mobile networks have diverse routing protocols of a different class. After research, we came to a conclusion that every protocol having some advantageous and limitation and every protocol cannot be deployed in every circumstance for underwater WSN there are different class of protocols. In this review paper a deep analysis carried out on proactive (table driven), reactive (on demand) and hybrid protocol. Further our main backbone is to know about those protocols which take minimum energy in health care system. The reference article having three protocols of different category DSR, DSDV, and AODV. Today advance and unorthodox applications for healthcare environments based on a wireless network are being flourished in the private enterprise. The prominent wireless networks are growing an elementary part of every single field of life. Our research work will be carried out in NS2.

An investigation on design of tall building structures with a hexagrid system using STAAD Pro

The advancement of technology and development of the economy of the world have brought the new era of tall buildings. The most efficient building system for high rises has been the tube-type structural systems. Nowadays, a particular structural system called a hexagrid system has caught the attention of engineers. In order to improve the efficiency of tube-type structures in tall buildings, as both structural and architectural requirements are provided well, a new structural system, called "Hexagrid", is introduced in this study. It consists of multiple hexagonal grids on the face of the building. However limited academic researchers have been done with the focus on the structural behavior, design criteria and performance assessment of this structural system. This study investigated the tall hexagrid buildings, focusing on the size and pattern of different hexagrid modules.
