Optical flow computation has been extensively used for motion estimation of objects in image sequences. The results obtained by most optical flow techniques are computationally intensive due to the large amount of data involved. A new change-based data flow pipelined architecture has been developed implementing the Horn and Schunk smoothness constraint;(More)
APPLICATIONS J. A. Boluda1 F. Pardo1 T. Kayser2 J. J. P erez1 J. Pelechano1 1Institut de Rob otica. Universitat de Val encia, Val encia, Spain 2Fachhochschule Mannheim, Mannheim, Germany ABSTRACT A foveated camera has been designed and fabricated. The camera is implemented using a new foveated CMOS sensor which incorporates a log-polar transformation. This(More)
This paper is concerned with a diierential motion detection technique in log-polar coordinates which allows object motion tracking independently of the camera ego-motion when camera focus is along the movement direction. The method does not use any explicit estimation of the motion eld, which can be calculated afterwards at the moving points. The method,(More)
Optical flow computation has been extensively used for object motion estimation in image sequences. However, the results obtained by most optical flow techniques are as accurate as computationally intensive due to the large amount of data involved. A new strategy for image sequence processing has been developed; pixels of the image sequence that(More)
This paper is concerned with a pipelined reconfigurable architecture for implementing image processing algorithms useful for robotic navigation. The computational complexity and the real-time application of these such algorithms suggest a custom hardware approach, but the wide quantity of different algorithms useful for different tasks suggest a software(More)
Selective change driven (SCD) Vision is a biologically inspired strategy for acquiring, transmitting and processing images that significantly speeds up image sensing. SCD vision is based on a new CMOS image sensor which delivers, ordered by the absolute magnitude of its change, the pixels that have changed after the last time they were read out. Moreover,(More)
This paper deals about the development of a PCI bus interface for a log-polar image acquisition system. The characteristics of the log-polar camera employed in our system, and its interface to a real-time image processing system, bind an ad-hoc solution that is difficult to achieve with any general purpose image acquisition system. Our main objective was to(More)
