An efficient and robust video watermarking algorithm for video coding standard MPEG has been proposed in this paper. Digital video watermarking has attracted a great deal of research interest in the past few years in applications such as digital fingerprinting and owner identification. Grayscale 2-D watermark patterns such as detailed trademarks or logos(More)
Video text information plays an important role in semantic-based video analysis, indexing, and retrieval. Text embedded in the image or video contains very useful information like the name of the person, title, location and sometimes brief description of the image. Many algorithms have been proposed to detect and localize the text information present in(More)
This paper proposed a technique of bit-rate control for video streaming over constant bit-rate communication channel, where the MPEG-2, standard variable bit-rate (VBR), is adapted to be used as a constant bitrate (CBR). The target image quality and by feedback based on the buffer level controlled on the output rate of the video encoder. A CBR transport(More)
Data mining process suffers from the curse of dimensionality. If a dataset has a large number of attributes, then the corresponding classification procedure loses its accuracy and precision. In this paper, an efficient algorithm for dimensionality reduction using Reducts through Ranking based on Rough Set Theory is presented. Classification process is(More)
Reliable Node based routing (RNBR) is a trust based routing protocol for mobile adhoc network which presents reliable nodes for efficient routing to achieve high throughput. It is always a challenge to secure a node from internal and external adversaries' attack, which impact the reliability of the node. This paper presents a light weight node securing(More)
