Abstract There is a gap when representing detailed information related to public on maps due to limitations of underlying data sources. The purpose of this research is to scan the research output on Geographical Information Systems (GIS) and relational databases, then develop an implementation by combining these two technologies GIS and graph databases in order to fill the identified research gap. The outcome of... There is a gap when representing detailed information related to public on maps due to limitations of underlying data sources. The purpose of this research is to scan the research output on Geographical Information Systems (GIS) and relational databases, then develop an implementation by combining these two technologies GIS and graph databases in order to fill the identified research gap. The outcome of this implementation is a central Geospatial intelligence on graph which delivers benefits in the context of multiple data source integration and open sources. Read More Read Less

Abstract This paper represents the wavelet techniques used for compression of gray scale and true color images. An image compression method is applied on the EZW and WDR. These techniques are more efficient and provide a better quality in the image. In compression, wavelets have shown a good adaptability to a wide range of data, while being reasonable complexity. The above techniques have been... This paper represents the wavelet techniques used for compression of gray scale and true color images. An image compression method is applied on the EZW and WDR. These techniques are more efficient and provide a better quality in the image. In compression, wavelets have shown a good adaptability to a wide range of data, while being reasonable complexity. The above techniques have been successfully used in many applications. The techniques are compared by using the performance parameters PSNR and MSE has been successfully implemented to provide high compression rates maintaining ratio can be reached to good quality of the image with different level wavelet codes. The objective of this paper is to implement the concept of wavelet based image compression to gray scale images using different techniques. The techniques involved in the comparison process of EZW and WDR. Read More Read Less

Abstract Emerging multimedia applications demands content-based video processing. Video has to be segmented into objects for content-based processing. A number of video object segmentation algorithms have been proposed such as semiautomatic and automatic. Semiautomatic methods adds burden to users and also not suitable for some applications. Automatic segmentation systems are still a challenge, although they are required by many applications. The proposed work aims at... Emerging multimedia applications demands content-based video processing. Video has to be segmented into objects for content-based processing. A number of video object segmentation algorithms have been proposed such as semiautomatic and automatic. Semiautomatic methods adds burden to users and also not suitable for some applications. Automatic segmentation systems are still a challenge, although they are required by many applications. The proposed work aims at contributing to identify the gaps that are present in the current segmentation system and also to give the possible solutions to overcome those gaps so that the accurate and efficient video segmentation system can be developed.
