Are two users more likely to be friends if they share common interests? Are two users more likely to share common interests if they're friends? The authors study the phenomenon of homophily in the digital world by answering these central questions. Unlike the physical world, the digital world doesn't impose any geographic or organizational constraints on friendships. So, although online friends might...
This paper proposes an efficient expression invariant algorithm for 3D face recognition of subjects. The proposed algorithm uses a surface-based approach to extract automatically and to define geometrically the facial features like eyebrows, nose and lips. These extracted features are used to obtain some unique control points that can be used for matching. The algorithm is tested on Binghamton University...
Predominant resources for execution of any process are computational power and memory. In current Distributed system approaches, when the host system memory is overloaded and a process is executed on a remote system, then all the files, used by the process must also be transferred to the remote system. The host system may already be overloaded and it needs to transfer required files which in turn...
Quality of tuberculosis (TB) diagnosis by manual observation varies depending on the quality of the smear and skill of the pathologist. To overcome this problem, a method for diagnosis of TB from ZN-stained sputum smear images is presented in this paper. Hue color component based approach is proposed to segment the bacilli by adaptive choice of the hue range. The bacilli are declared to be valid or...
Analysing datasets requires sophisticated techniques which can help to unearth interesting patterns. One approach is to mine multidimensional association rules from data. The traditional association rule mining relies on uniform support and confidence values which does not always yield interesting rules due to varied nature of data. This paper presents a novel approach to mine multidimensional association...
We present a virus detection-and-removal service architecture for digital ecosystems which is inspired by biological ecosystems. This service becomes active as soon as a virus infection of a machine is identified. In a biological ecosystem, as a virus is found to be active, all organisms infected by it need to be identified and treated. In some cases, if they cannot be treated, the only option left...
It has been shown by researchers that using a multimodality approach can help in identifying better clusters in an image collection. The multimodal image features include low-level image features and available text annotations. This approach helps in identifying inherent relationships among different types of features associated with an image. In our approach, we divide images into small tiles and...
In this paper, we consider the single frequency network (SFN) operation of broadcast/multicast services, and develop resource allocation schemes to minimize the amount of resource over-provisioning. Over-provisioning is required when SFN areas are overlapping because all the cells in the SFN area should use the same resource to transmit a given MBMS service. We first develop an optimal resource allocation...
