This paper proposes a programmable high-performance architecture of datapath in the merged DRAM logic (MDL) for video signal processing. A model of a datapath in the programmable MDL is generated, and two basic parameters, total required clock cycles (TRCC) and DRAM access rate (DAR), are defined by analysis of the model. Design guidelines are suggested for the optimized video signal processor ...

Image and video processing applications involve large multidimensional signals which have to be stored in memory modules. In application-specific architectures for real-time multidimensional signal processing, a significant cost in terms of chip area and power consumption is due to these background memory units. The multidimensional signals are usually modeled in behavioral descriptions with ar...

The ability of modern telecommunication services to adapt more and more aspects of their service to users’ needs is becoming of crucial importance. This is due to the fact that these services are getting increasingly complex and are also entering the user’s extremely sensitive social domain. Approaches developed to mitigate these issues rely on user data acquired in a non-intrusive way. Social ...

annihilation or reduction of each kind of noise blended in correct data signals is a field that has attracted many researchers. it is a fact that fuzzy theory presents full capability in this field. fuzzy filters are often strong in smoothing corrupted signals, whereas they have simple structures. in this paper, a new powerful yet simple fuzzy procedure is introduced for sharpness reduction in ...

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 ...

A design method of quantizers in sampled-data systems is proposed. The design objective is quadratic stability in the continuous-time domain, and thus the decay rate of the systems between sampling times is guaranteed. Our general treatment enables us to look for quantizers efficient in terms of data rate.

Throughout the past several decades, much research has been done in the area of signal processing. Two of the most popular areas within this field have been applications for speech recognition and image processing. Due to these extended efforts, today there are systems that can accurately recognize and transcribe the daily television news programs that are broadcast to our homes. There are also...
