Necessity of digital video stabilization has come into view as a very challenging field with the mounting demand of digital imaging devices. Videos captured by such devices endure some unwanted motions in the frames of videos, which are mostly ending of free body or environmental vibrations. These vibrations cause an obvious dwindling in the visual feature of the captured video. Along with this, videos...
At the present time 3D video technique has been attracting the attention of both academic and industrial world. Multiview video technique is a new 3D video formation technique which can be used in application like 3D televisions and also for entertainment purpose. Large numbers of views are required for such a display which results in increase of bandwidth. Thus multiview video compression scheme...
Most practical methods of the speech recognition (SR) are dependent on the feature extraction schemes used in the implementation. The performances of these SR systems are highly affected by the presence of noise. By passing speech signal through cochlear filter bank (CFB) prior to the feature extraction reduces the impact of the noise on the system. In this paper, noise robust approach of feature...
“Security has its importance and application in wide area. It is a measure of human negligence, in desire to seize the latest technological inventions”. This measure may have adverse effect on human perception to the deployment of application, which needs serious concern in terms of security. Audio steganography is a technique used to transmit hidden information by modifying an audio signal in an...
ECG is a prime important signal for coronary heart diseases which focuses on electrophysiology of heart. Quality diagnosis of ECG is a technological challenge. In high quality diagnostic analysis of the bio-potential signals such as ECG, power line interference (PLI) sometimes referred to as ac pickup or hum is a common problem in recording situation. Especially if computer interpretations of the...
Processing of large amount of data is an important aspect of Speech Recognition (SR). However, to formulate speech recognition system in small devices is not simple. This paper suggests Digital Signal Processor (DSP) based speech recognition system with improved performance in terms of recognition accuracies and computational cost. The comprehensive survey of various approaches of feature extraction,...
