In this paper we introduce a large area integrated circuit (LAIC) called MAXPE9 which integrates 9 programmable video signal processing elements (PEs) on an area of 16.6 cm . Each PE 2 has a peak arithmetic performance of 1 giga operations per second (GOPS). Due to yield considerations redundancy concepts have been implemented that -even in the presence of production defectsresult in working ch...

Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

In this paper, the authors conduct a review on redundant wavelet transform (RDWT) in video signal processing. As an over-complete version of discrete wavelet transform (DWT), RDWT provides several advantages over the traditional DWT. In video coding area, we utilize its shift-invariant property and its phase-diverse multihypothesis, which are not provided by DWT, to build high performance video...

background: video-based instruction has been stated as an effective method of teaching and its potentials have encouraged instructors learners to opt this method purpose: the current study has compared the students' cognitive learning in the two approaches of lecture- based and video-based teaching. methods: this quasi-experimental study was conducted on 88 senior nursing students who were rand...

Historically, multiple description coding (MDC) and post-processing error concealment (ECN) algorithms for video have evolved separately. Although multiple description coding provides a way to make the video quality degrade gracefully in the presence of packet losses, the resulting quality may be unsatisfactory when only one description is used to reconstruct the signal. This paper proposes a c...

Computation aware scheme for video signal processing is proposed in this paper. Computation power and time is reduced by dynamically scheduling usage of processor resources environment for video sequence depending up complexity of the video. And different video coding algorithm is selected depending upon the nature of the video. Simulation results show the effectiveness of the proposed method.

Stereo video is regarded as an important developing trend of video technology and there is an increasing need to develop efficient and perceptually consistent methods for stereo video quality evaluation in the fields of stereo video signal processing. In this paper, a perceptual metric for stereo video quality evaluation is proposed based on the state-of-the-art physiological and psychological ...
