Image Mosaicing and Producing a Panoramic Visibility

Aim of this research paper is to take multiple input images , the input images are having some of the overlapped region with one another. Since digital cameras cant take photos of a wider view, for a wider view we need a highly sophisticated camera. It is therefore being attempted to develop enabling methodology which can convert the corresponding images captured form such cameras into a panoramic view. In this paper a n algorithm is used and applied some of the advanced function available in matlab to make this work much more efficient

A New PDAC (Parallel Encryption with Digit Arithmetic of Cover Text) Based Text Steganography Approach for Cloud Data Security

Internet Computing provides dynamic virtualization, resource pools, services and high availability servers. With rapid growth of internet computing technology, there is a high demand for data storage security on cloud. In this paper we are presenting a useful new approach of text based steganography for cloud data security. In our approach, simple addition, subtraction and multiplication of digits of ASCII code of each character of cover text is done and these new generated numeric values are used to encrypt ASCII values of our plain text. Since, in our approach, there are three basic airthmetic operations that are performed on every character of cover text, therefore, after airthmetic calculations each and every character will generate three numeric values such that, each and every numeric value will encrypt two ASCII values of plain text parallely. One from beginning of array of ASCII values of plain text and another one from ending of the very same array. In our approach, one character of cover text hides at most six characters of plain text. Thus memory allocation problem for cover text and execution time both are reduced. Using parallelism performance of our approach is enhanced. DOI: 10.17762/ijritcc2321-8169.15039

Ultra Wideband Wearable Sensors for Motion Tracking Applications

The increasing interest and advancements in wearable electronics, biomedical applications and digital signal processing techniques have led to the unceasing progress and research in novel implementations of wireless communications technology. Human motion tracking and localisation are some of the numerous promising applications that have emerged from this interest. Ultra-wideband (UWB) technology is particularly seen as a very attractive solution for microwave-based localisation due to the fine time resolution capabilities of the UWB pulses. However, to prove the viability of utilizing UWB technology for high precision localisation applications, a considerable amount of research work is still needed. The impact of the presence of the human body on localisation accuracy needs to be investigated. In addition, for guaranteeing accurate data retrieval in an impulse-radio based system, the study of pulse distortion becomes indispensable. The objective of the research work presented in this thesis is to study and carry out experimental investigations to formulate new techniques for the development of an Impulse-radio UWB sensor based localisation system for human motion tracking applications. This research work initiates a new approach for human motion tracking by making use of pulsed UWB technology which will allow the development of advanced tracking solutions with the capacity to meet the needs of professional users. Extensive experimental studies involving several ranging and three dimensional localisation investigations have been undertaken, and the potential of achieving high precision localisation using ultra-wideband technology has been demonstrated. Making use of the upper portion of the UWB band, a novel miniature antenna designed for integration in the UWB localisation system is presented and its performance has been examined. The key findings and contributions of this research work include UWB antenna characterisation for pulse based transmission, evaluation of comprehensive antenna fidelity patterns, impact of pulse fidelity on the communication performance of a UWB radio system, along with studies regarding the effect of the human body on received pulse quality and localisation accuracy. In addition, an innovative approach of making use of antenna phase centre information for improving the localisation accuracy has been presented
