Condensation Tracking through a Hough Space

Recent work has shown tracking groups of lines through the parameter space represented by a Hough accumulator array to be efficient and insensitive to both occlusion and changes in illumination. Previous methods [1,2] have, however, been less robust in the presence of distractions. Distractions are a challenge to trackers of all types, but the problem is heightened in the Houghbased approach as short collinear segments give the same response as an equal length connected line. We describe the application of the Condensation algorithm to tracking peaks through a Hough accumulator array, producing a tracking technique that is efficient and robust under illumination changes, occlusion and distractions.
