It runs at video rates using standard PC hardware. In tracking, an object of interest is first recognized and located approximately, which can be expensive computationally. Woodfill, J. and B. Von Herzen. IEEE Workshop on FPGAs for Custom Computing Machines. Real-time stereo vision on the parts reconfigurable computer .
Continuous detection depends on the availability of a fast detection method.
Stereo provides a stable basis for segmentation. J. Woodfill and B. Von Herzen. This section describes a simple method for image extraction which can be used in replacing a real background by a synthetic image. The shaded components are common to both designs and do not need to be reconfigured.
