Measuring Scene Complexity to Adapt Feature Selection of Model-Based Object Tracking

Motion and scene complexity for streaming video games

“…Experimental results are given to illustrate the proposed method. Minu et al [1] use scene based motion features as an element for robotic vision tracking. In particular, their experiments show the success of the approach to disambiguate features in complex scenes.…”

“…In fact, thin clients, there the local computer is primarily an input and output device and the remote computer does the majority of the processing, have seen a resurgence in use because today's networks can support bandwidthintensive, client-server interactions. 1 Thin clients were made popular in the late 1980's by the use of X-terms, but network connectivity has made them increasingly viable today [14]. Computer games have seen tremendous growth in recent years, as well, with the end of 2006 seeing gross revenue from U.S. computer game sales at $7.4 billion, 2 on par with domestic box office ticket sales.…”

Integrated vision system for the semantic interpretation of activities where a person handles objects

“…It extends edge-based tracking of geometrical features (lines, ellipses, arcs) towards integrating intensity and colour cues depending on object and background information. Depending on the perceived scene complexity each feature can evaluate the present detection quality and use this to fine tune the cue integration process [2]. While the initialisation using the OD takes about one second, tracking using EPIC operates at frame rate.…”
