The secret image can be reconstructed by stacking the shares together, with no complex cryptographic calculations. This paper proposes a new VC scheme for color images. The shares generated are similar to the cover images, thereby reducing the suspicion of data encryption. The proposed scheme makes use of Jarvis error filter, a key table and specialized tables for coding. High visual quality is achieved as up to 50 percent of the secret image can be recovered.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132404406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mobile station (MS) requires handoff when it travels out of the coverage area of its current access point (AP) and tries to associate with another AP. But handoff failure probability provides a serious barrier for such services to be made available to mobile platforms. Throughout the last few years plenty of research had been done to reduce handoff failure probability, whereas very few of them can be applied for an irregular (haphazard) motion of MS. In this paper, we are going to implement a new handoff scheme which is applicable for both regular and irregular motion of MS. We will find the minimum time interval (T) that the MS should stay within the handoff region (the particular area within a cell where the handoff is initiated and performed). We will repeat the scanning process number of times at different points of MS trajectory within the handoff region until the total scanning time exceeds the fixed time interval (T) and by doing so we can find out the most significant AP. Our simulation results show the effectiveness of our proposed scheme in practical field.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130812822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Saliency map represents the significance of objects in the scene. As in a visual scene all objects do not get equal attention. Objects which are different from their surroundings, automatically get more visual importance. Hardware based eye tracker devices are commercially available but the cost is comparatively very high. So to match the gaze attention, various algorithms are explored by several researchers. In this paper, multiscale phase spectrum based efficient saliency detection method is proposed. The proposed method is performing better by yielding better results than other methods. Four state-of-art of salient object detection techniques are analyzed along with the ground truth and compared against the proposed method for experimental evaluation.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115226013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To build such a system `Robot-Cloud' is prepared which extends the functionality of a robot. A `Robot-Cloud' is designed and implemented with components like cloud controller, ROS master node, storage unit, Map-reduce computing cluster and robotic services. In this system every robot is facilitated with ROS capability that helps to provide abstraction over hardware, heterogeneity and communication over TCP/IP. All the robots communicate with a master node present at the cloud controller to avail communication with other robots and to request services from the cloud. Our system supports all three basic service models i.e. Saas, PaaS and IaaS by incorporating typical SOA (Service Oriented Architecture) functionality. This approach can also be utilized to achieve a common goal for the networked robots. Finally, some simulation results are given to support the claimed framework.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114542399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selection of an optimal regular-shaped pattern set for very low bit-rate video coding, focusing on moving regions has been the objective of much recent research in order to try and improve bit-rate efficiency. An approach to Variable Size Block Matching is also implemented, based on the binary partitioning of blocks. If a particular block does not allow for accurate motion compensation, then it is split into two using the horizontal or vertical line that achieves the maximum reduction in motion compensation error. This method causes partitioning to occur along motion boundaries, thus substantially reducing blocking artifacts. In addition, small blocks are placed in regions of complex motion, while large blocks cover regions of uniform motion. Also the paper is a review of the block matching algorithms used for motion estimation in video compression. It implements and compares 7 different types of block matching algorithms that range from the very basic Exhaustive Search to the recent fast adaptive algorithms like Adaptive Rood Pattern Search.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127141754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The position and width of the notch-band can be adjusted in the entire operating band. A prototype of the antenna has been designed on FR4-Epoxy substrate dielectric constant 4.4 and thickness h=1.53 mm with a N-shape slot in coplanar waveguide feed of length L = 7.4 mm and slot width W = 2.8 mm. The experimental result of this antenna exhibits ultra wide band characteristics from frequency 3.1 GHz to 15.0 GHz. The notch in operating band helps to reduce the interference with the frequency bands of Wireless Local Area Network (WLAN). The simulated and experimental return losses are found in good agreement. The experimental radiation of this antenna in azimuth plane is nearly omni-directional. This proposed cpw-fed circular square corner fractal antenna with varying notch-band frequency characteristics can thus be used for Ultra wide band (UWB) system, microwave imaging, precision position system, and radar tracking system.","PeriodicalId":319467,"journal":{"name":"2012 International Conference on Communication, Information & Computing Technology (ICCICT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130160359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
