Improving the performance of surveillance systems using basic features of the video images (color, edges and structure)

This Research suggests a new mechanism that aims to increase the effectiveness of surveillance systems by extracting the moving objects coming from surveillance camera in order to identify them and propose a new mechanism for indexing and storing in database and classified them according to the basic characteristics and strong indicators and retrieval when needed in less possible time. The basic idea lies in the combination of the basic characteristics of the goal (color, edges and texture) which ensures the best performance in extracting the basic target features and depend on it as indexes, then nonlinear transfers has been done on the edges of the target in order to get a picture bearing the minutest details, then conducted adverse transfers on the edges of the target during the process retrieved from the database. Finally, we propose a new mechanism for indexing all images tabase to Retrieval them in best accuracy and less time, and a program had been achieved to realize this idea.

Study of Data Size Changing Effect on Performance of Cloud, Hybrid, And Traditional DBMSs

With the rapid growth of the size of the data stored in the cloud systems, the need for effective data processing becomes critical and urgent. This research introduces a study of the most important characteristics of databases management systems: Hive, SQLMR, and MariaDB Galera. Hive is a cloud database management system. SQLMR is a hybrid system, which depends on the integration between the cloud and traditional systems capabilities. While MariaDB Galera is a traditional database management system developed to cope with the cloud characteristics. In this research, we show the most important developments that have been on those systems, and then we compare their performance in data processing based on the execution time of query operations with the change of the volume of data. That is to identify the performance of those systems practically and to know the developing requirements for access to optimized data management system, and to help users in the selection of the database system that achieves their requirements in terms of availability and scalability.

Access Time Reduction To Image Files Using Enhanced B+ Tree Indexing Method

The Research suggests a novel model aims to reduce the time of search for image files by proposing a new indexing mechanism to avoid the plague algorithm used with indexing so that the access time to these files becomes as less as possible. The first stage in this paper is to clarify the importance of archiving in organizing files via designing a database, storing images in it and recording the times needed to obtain the required files from the database. Then the indexing process for image files stored in the database is applied by proposing a new algorithm -B+ Tree enhanced- for organizing image files according to a certain mechanism to facilitate accessing any file, conducting queries and recording the times used to get those files from the database to compare them with the times required to access files before indexing in order to show the efficiency of the proposed method.

Legal problems faced by the organization of digital technology ((An Empirical Study on some developed countries))

This Article addresses the interaction between digital technology and Intellectual Property Law. Despite its obvious benefits, the Internet was and still is a major source of legal obscurity. The one million dollar question is to what extent, if at all, can the law of intellectual property strike the correct balance between innovation and the protection of Intellecual Property Rights? Keeping the concepts of digital liabraries, peer 2 peer systems and second life, answering the previous questions seems to be easirer said than done. Keeping the above in mind, this Article highlights the legal argument in the United States of America, Canada and the UK. As such, it does focus, unexclusivily, on the Common Law System. The conclusion we have reached is that any answer could be anticipated to deal with these technological issues from a legal point of view should not be taken as an excuse to hinder the development of business

Automation of Topographic map from CAD to Geo Database in GIS

GIS software provide manual import tools to maps produced on CAD software to be transformed to geo-database. This operation consumes time and effort. The "transformation" however will not be adequate unless we analyze the relation between CAD and GIS software in preparing maps. The question raised here if this relation competitive or integrative? This research tries to answer this matter by studying it from different angles: modeling, spatial feature, scale, spatial analysis and data management. Analyses reveal that this relation isn't competitive at all, but rather integrative, as CAD software produce technical\design plans, whereas GIS software are dedicated for the production of general and thematic maps. Thus, CAD based spatial data (topographic, cadastral, master plans) could be "up-graded" to be efficient in GIS environment. However available tools to make this are basically manual, and for that, an automated approach was developed to execute this upgrade from CAD to GIS. This new approach was applied and evaluated and the output results were satisfactory accurate, time\effort saving, and indeed didn't miss any of CAD layers. This all could be achieved if being conditioned with the approach constrains.

Building 3D Digital Models For Cities in Large Topographic scales in GIS

3D GIS can be realized as an actual building platform of the urban space. This research develops automated 3D urban models that fit large-scale digital photogrammetry. Originally, modeling used manual or semi-manual techniques, and there is a need to for a development of an approach that automates the transformation of vector linear data, optimized by digital photogrammetry stations to create the 3D volume model in 3DGIS. This approach consists of three main phases: roof modeling, wall modeling and volume structuring. During the first phase, local and conditional "Delaunay Triangulation" method is used to deal with the majority of roof types regardless of its geometry. The second phase is completely automated to create the walls by the vertical projection (Top-Down) of the outer line of the roof into the Digital Terrain Model (DTM), and then by the selection of the bottom base level as the default level. Finally, different elements of the structure can be aggregated using spatial relationships (many-to-many) already supported by GIS software. The new approach is created and completely automated. It doesn't require roof geometric-types library, which asserts the GIS is a valid platform to build, to view and to store 3D urban models.

Intellectual Property for Databases in Syrian and comparative Laws

This research is on attempt to answer a question that is not dealt with completely by the Syrian Copyright Act of 2001 the research argues the essence of databases, by defining it, mentioning its characteristics and what makes it different from the other protected compilations; then it shows the rights which may arise on databases. After that, the research studies the protection which is granted by Syrian Law to the right holders of databases, whether they are authors or investors, arguing, in the scope of comparative study with, Arabic, foreign, and international statutes. the end, the researcher Lott the need to include databases with more individualized legal rules, which suit its special nature; the researcher recommends right holders to emphasize the importance of contractual protection since it provides a helping factor in reaching the satisfactory protection. ...
