Image and video compression has become an increasingly important and active area. Many techniques have been developed in this area. Any compression technique can be modeled as a threestage process. The jirst stage can be generally called a signal processing stage where an image or video signal is converted into a direrent domain. Usually, there is no or little loss of information in this stage....

Video signal processing is shifting from dedicated hardware to software implementation due to its flexibility. Digital signal processors (DSPs) for media processing are limited in its resources to enable cost efficient implementations for consumer devices. One way to achieve cost-efficient implementations is to use resource-quality scalable video algorithms (SVAs). This implies that dynamic res...

background: this paper proposes a new emotional stress assessment system using multi-modal bio-signals. electroencephalogram (eeg) is the reflection of brain activity and is widely used in clinical diagnosis and biomedical research. methods: we design an efficient acquisition protocol to acquire the eeg signals in five channels (fp1, fp2, t3, t4 and pz) and peripheral signals such as blood volu...

A vast amount of video data is generated around the world every day. Fast and efficient storage, indexing, browsing, and retrieval of video are necessary for the development of various multimedia database applications. Video fingerprinting is a proven and commercially available technique that can be used for content based copy detection. Fingerprints are compact content-based signatures that su...

Signal processing including analysis, understanding, detection, estimation, and modelling of the events and trends, the way they evolve, and the abnormalities and anomalies affecting them have attracted many researchers around the globe. Signal processing theory originates from mathematical foundation with astonishing applications which help information technologists discover and invent new rea...

Noise in video signal plays a major problem in most of the communication systems. Video denoising is the process of removing noise from the video signal. In order to increase compression effectiveness and improve subjective quality of video sequences video denoising process using Warped Filter is done. Warped Filter is an all pass filter; it is widely used for various video and audio processing...

Introduction Video and image processing applications are typically very computationally intensive. Given the increasing processing demands, the parallel processing capabilities of Altera® programmable logic devices make them an attractive implementation option for highly repetitive tasks found in video and imaging functions. Instead of using multiple programmable digital signal processors, a si...
