DSPs for image and video processing

نویسنده

چکیده

As communications get digital there is an increased use of image and video processing in embedded multimedia applications. Digital signal processors (DSPs) provide excellent computing platforms for these applications not only due to their superior signal processing performance compared to other processor architectures, but also because of the high levels of integration and very low-power consumption. This paper presents an overview of DSP architectures and their advantages for embedded applications. The speci"c signal processing demands of image and video processing algorithms in these applications and their mapping to DSPs are described. Recent results of successful implementation of two major embedded image and video applications } digital still cameras and video phones } on TI's TMS320C54x DSP series conclude the paper.

Scalable Video Algorithms for Resource Constrained Platforms

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...

DSP-oriented low level processing for adaptive tuning of video surveillance images

Natural scenes often have a dynamic range (DR, rang of luminance) of up to 6 decades. An image sensor has to resolve this range with approximately 100 values per decade to generate a digital representation containing all details relevant for surveillance [Hecht, Kandel]. Since conventional CCD image sensors have a DR of 2,5 decades (mapped to 8 bit), they are not applicable for surveillance of ...
