Abstract: In this paper we present a new algorithm to design and implement a fully automatic system with high level of accuracy to convert digital image to Excel sheet and comparing two images to find the discrepancy between them. Matrix-based are a useful tool for exploring relationships between related records in a data set. Relationships can be any relation between two records, but are generally similarity or dissimilarity measures. Converting image to Excel file provides the possibility of dealing with the image matrix and makes any mathematical operations on the image much easier to the user. Experimental results from test images data are given to demonstrate the performance of the proposed program and algorithms. The program was written in Visual Basic.Net.

Abstract: In the most common standard coding schema of the image, coder has greater complexity than the decoder, usually 5-10 times higher. In wireless sensor networks is the opposite, the coder is implemented in a battery feed device, having so very limited power resource, while the decoder is typically implemented in a powerful computer. The paper will focus on a combination of wavelet technique with algebraic GPCA method, realizing an improvement of traditional wavelet technique, providing a suitable compression of multimedia information without reducing its quality. Simulations in MATLAB provide desired compression levels. The proposed method, unlike other existing methods, takes into account the structure of multi-modal data, except the correlation in 1 D and 2 D it takes in consideration correlation between color channels. The method gives a significant improvement in the PSNR values ??reaching an average of 15% compared with traditional wavelet compression.

Abstract: Vendors of Database Management Systems (DBMS) and Enterprise Platforms, actively compete between each other to develop new features of their products. However, many problems, such as joint data processing or management of Data Lifecycle can be solved easier and more efficient with the Data Management Technology (DTM). Increasing amount of information and rapid development of Information Systems (IS) –are two interrelated processes: the high growth of data requires a similar development of its processing tools, which’s improvement stimulates the processing of ever larger amounts of data. Today, practically in every more or less large organization,  activities are being  built around the Corporate Information System (CIS) (and often multiple systems), most of which are built on Relational Database Management Systems (RDBMS) with  three-tier architecture: client applications - application servers - databases servers. When designing every such system several problems related to data management have to be solved.

Abstract: Ad-hoc networking is a concept of computer communications is that the users wanting to communicate with each other form a temporary network, without any form of centralized administration. The purpose of a routing protocol is each node participating in the network acts both as host and a router and must be --- to forward packets for other nodes. An ad-hoc network has certain characteristics which imposes new demands on the routing protocol. The most important characteristic is the dynamic topology, which is a consequence of node mobility. Nodes can change position quite frequently, which means that we need a routing protocol that quickly adapts to topology changes. The nodes in an ad-hoc network can consist of laptops and personal digital assistants and are often very limited in resources such as cpu capacity. Storage capacity, battery power and bandwidth. With this protocol should try to minimize control traffic, such as periodic update messages. Instead of routing protocol only reactive can be calculate routes based on specific request. Here we have two protocols like reactive and proactive. In this paper we can try to compare the protocols, then we can identify which is perform well when mobility is high. The size of the network and the traffic load affects protocols based on source routing like DSR to some extent. A large network with many mobile nodes and high offered load will increase the overhead for DSR quite drastically. By observation a hop-by-hop based routing protocol like AODV is more desirable.

Abstract: Image processing algorithms are being developed for enrollment and correction of multiple adjacent images, channeling the stitched results to an image database for storage/retrieval adapted to the needs of users. The aim of this work is to facilitate the capture of high-resolution digital images of decorated surfaces in historical buildings. It will be possible to position the camera repeatedly to an accuracy of 1 mm, using laser positioning devices, with three degrees of freedom on top of the robotic mast, including 360° horizontal rotational movements for the capture of full panoramic images. This paper will refer to the issues of planning on-site photography, positioning of camera and illumination relative to the surface, control of the robotic apparatus, use of calibration charts, processing and database storage of images, and evaluation of the results. The image acquisition software chain and image processing applications including mosaicing techniques will be described in relation to the image capture of faraway surfaces including stained glass windows.
