Multiresolution Pyramid Architectures for Real-Time Motion Analysis
نویسنده
چکیده
Multiresolution pyramid techniques can improve the efficiency of basic vision algorithms by orders of magnitude. They will be key to developing practical vision systems to perform challenging tasks in real time. However, these efficiencies cannot be fully realized when pyramid-based algorithms are implemented on machines with conventional SIMD mesh and pipeline architectures. We describe a segmented pipeline architecture that can support pyramid processing. We illustrate this architecture with an application to image motion analysis for vehicle guidance.

Real-time foveated multiresolution system for low-bandwidth video communication
Foveated imaging exploits the fact that the spatial resolution of the human visual system decreases dramatically away from the point of gaze. Because of this fact, large bandwidth savings are obtained by matching the resolution of the transmitted image to the fall-off in resolution of the human visual system. We have developed a foveated multiresolution pyramid (FMP) video coder/decoder which r...

متن کاملMethods and Approaches for Real-Time Hierarchical Motion Detection
The recent work on perception and measurement of visual motion has consistently advocated the use of a hierarchical representation and analysis. In most of the practical applications of motion perception it is absolutely necessary to be able to construct and process these hierarchical image representations in real-time. First, we discuss a simple scheme for coarse motion detection that highligh...

متن کاملMultiresolution Motion Estimation Techniques for Video Compression
Wavelet transform is a valuable tool in video processing applications because of its flexibility in representing nonstationary signals . Wavelet-based compression has the advantages of efficient decorrelation of image frames and reduced complexity multiresolution motion estimation (MRME). In this paper, we propose three techniques to improve motion estimation in a wavelet-based coder. First, we...
