Video is one of the sources for presenting the valuable information. It contains sequence of video images, audio and text information. Text data present in video contain useful information for automatic annotation, structuring, mining, indexing and retrieval of video. Nowadays mechanically added (superimposed) text in video sequences provides useful information about their contents. It provides...

In this paper, a new directionally adaptive, learning based, single image super resolution method using multiple direction wavelet transform, called Directionlets is presented. This method uses directionlets to effectively capture directional features and to extract edge information along different directions of a set of available high resolution images .This information is used as the training...

Purpose. To provide PET/CT image fusion with an improved PET resolution and better contrast ratios than standard reconstructions.Method. Using a super-resolution algorithm, several PET acquisitions were combined to improve the resolution. In addition, functional PET data was smoothed with a hybrid computed tomography algorithm (HCT), in which anatomical edge information taken from the CT was em...

379  Abstract— The Iterative back-projection (IBP) is a classical super-resolution method with low computational complexity that can be applied in real time applications. This paper presents an effective novel single image super resolution approach to recover a high resolution image from a single low resolution input image. The approach is based on an Iterative back projection (IBP) method com...

Numerous automatic continuous emotion detection system studies have examined mostly use of videos and images containing individual person expressing emotions. This study examines the detection of spontaneous emotions in a group and crowd settings. Edge detection was used with a grid of lines superimposition to extract the features. The feature movement in terms of movement from the reference po...

Let G1, G2, ..., Gn be a family of disjoint stars. The tree obtained by joining a new vertex a to one pendant vertex of each star Gi is called a banana tree. In this paper we determine the super edge-magic total labelings of the banana trees that have not been covered by the previous results [15].

High-Resolution (HR) images play vital role in almost every aspect of day-to-day life. The spatial resolution and the quality of the images can be improved with help of Super Resolution (SR) techniques. It rebuilds a HR image from one or multiple LowResolution (LR) images. During the application of these Super Resolution (SR) methods, some intricate details in the given low resolution image may...

Tian and Meng in [Y. Tian and J. Meng, c  -Optimally half vertex transitive graphs with regularity , Information Processing Letters 109 (2009) 683-686] shown that a connected half vertex transitive graph with regularity and girth is cyclically optimal. In this paper, we show that a connected half vertex transitive graph G is super cyclically edge-connected if minimum degree k k   6 g G   ...
