In this paper, a method for automatic detection and efficient segmentation of brain tumor from magnetic resonance imagery has been introduced. We have proposed a variant bounding box technique for detecting brain tumor that utilizes approximate symmetry associated with the brain in an axial MR image. It detects the brain tumor by exactly circumscribing an(More)
Mobile Ad-hoc network (MANET) is an autonomous system of mobile nodes/devices connected by wireless links. These mobile nodes are free to move anywhere in the network without any centralized control. Multimedia applications are gaining great popularity in MANETs as these networked and portable devices are becoming more powerful and more multimedia enhanced.(More)
An explorative work on texture feature extraction through oblong aperture for the non random type of texture images is presented in this paper. These features are further useful for segmenting the texture regions using the level set framework. The statistical moment descriptors are obtained within a small aperture and are embedded into a level set frame(More)
