Existing routing algorithms treat Quality of Service (QoS) parameters and secure routing as completely separate entities requiring separate algorithms. In this paper we propose secure QoS Distance Vector and secure Bellman-Ford-Moore routing algorithms that meet QoS requirements and satisfy security concerns. Security is achieved by placing filters in the network. The routing algorithms generat...
The higher resolution image can be reconstructed from lower resolution images using SuperResolution (SR) algorithm based on Support Vector Regression (SVR) by combining the pixel intensity values with local gradient information. Support Vector Machine (SVM) can construct a hyperplane in a high or infinite dimensional space which can be used for classification. Its regression version, Support Ve...
A unified medical image retrieval framework integrating visual and text keywords using a novel multi-modal query expansion (QE) is presented. For the content-based image search, visual keywords are modeled using support vector machine (SVM)-based classification of local color and texture patches from image regions. For the text-based search, keywords from the associated annotations are extracte...
In this paper, we propose a video Watermarking technology to hide copyright information by a slight modification of the motion vector, in MPEG2 video bitstream. In this method, watermark is embedded in the motion residual of large value motion vector, then the motion residual are regularized into a modified bitstream, from which the watermark information can be retrieved easily and exactly. Fro...
background: mesenchymal stem cells (mscs) are ideal cells for cell and gene therapy. however, the low survival of mscs after transplantation has limited their applications. we aimed to evaluate the expression of cytoprotective genes including nqo1, txnrd1, ho-1, gclc following the over expression of nrf2 in umbilical cord-derived mscs (uc-mscs). methods: 3-5 passages of uc-mscs were cultured. r...
In this paper, we proposed the distribution of mesh normal vector direction as a feature descriptor of a 3D model. A normal vector shows the entire shape of a model well. The distribution of normal vectors was sampled in proportion to each polygon's area so that the information on the surface with less surface area may be less reflected on composing a feature descriptor in order to enhance retr...
