Image Enhancement is one of the most important concerns in Digital Image processing which is used to process the image so that we can view and assess the visual information it contains with greater clarity. In this Work a 2-step Image De-noising and Enhancement Algorithm is proposed i.e. the application of Improved Median Filter and Morphological Operations. In the First step Image is enhanced using a 3x3 neighborhood window processing and then using Morphological Operations to further enhance it. Our Method can remove salt-and-pepper-noise with noise level as high as 80%. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering. Source

This paper proposes Unit Commitment solution based on the Shuffled complex evolution with Principal component analysis algorithm-University of California at Irvine. The features of the proposed algorithm are: It solves the problem of population degeneration. It combines the strength of shuffled complex, the Nelder-Mead simplex and multi-normal resampling to achieve efficient optimization. By representing the chromosome intelligently, the chromosome length and population size is reduced. The effectiveness of the proposed algorithm is tested on standard 10, 40, 80 and 100 units, 24 hour power system. Simulation results obtained illustrate that the proposed algorithm can produce global optimal solution compared to that of other reported methods. © 2014 Praise Worthy Prize S.r.l. - All rights reserved.

In this paper the concept of Visual Secret Sharing and Discrete Wavelet Transform (DWT), are used to split the watermark into two random binary images called shares. One share is generated during watermark embedding phase and is kept secret with an arbitrator. The other share can be extracted from the controversial image whenever needed. Both the shares can be combined to decode the original watermark. The proposed scheme aims at reducing the size of shares, improving the quality of extracted watermark, and decreasing the probability of false positives. Hence it offers better security when compared to the related schemes. The simulation results reveal that the proposed scheme is robust to several image processing attacks. © 2012 IEEE. Source

As the technology advances the human needs do grow towards comfort. VMAIL- Voice Enabled Mail Reader, system developed for person who requires comfort and is essential for a person with disability. The speech synthesis embedded in VMAIL system can read aloud any written text, avoiding eye strain and save time, reading on the computer. This is a web based system developed using HTML and java. It can be employed as an aid for the people who suffer with visual impairment. It helps us to convert written Telugu text to audio files and play them. The user can receive, compose and send a mail to another VMAIL user. A VMAIL user has an added benefit over other email systems because it provides an option for the user to read his mails aloud that are in their native language, reducing his strain. It has easy-to-use, user-friendly interface with readable buttons and most functions can be performed with a simple mouse click or menu selection. © 2010 IEEE. Source

Simple, specific, accurate and precise UV-visible spectrophotometric methods have been developed for the estimation of five drugs viz., Amlodepine besylate, Esmolol hydrochloride, Olmesartan medoxomil, Phenyl ephrine hydrochloride and Tramadol hydrochloride. These methods involve the addition of a known excess of NBS to the drugs in acid medium followed by estimation of residual NBS by reacting with a fixed amount of Amaranth and measuring the absorbance of the dye at 520nm. The proposed methods were found to be successful for the estimation of these drugs in bulk and their formulations. The results of analysis have been validated statistically for linearity, accuracy, precision, LOD and LOQ. Source
