Active Blobs

Active blobs are deformable, view-based models. The models can robustly track nonrigidly deforming shapes at speeds approaching video frame-rate on a standard graphics workstation. To gain better robustness, active blobs incorporate information about not only shape, but also color image appearance. Active blobs also provide some robustness to photometric variations, including specular highlights and shadows. By taking advantage of texture mapping hardware available in many workstations, active blobs have achieved peak rates of over twelve frames/sec. on an SGI Indigo2 Impact R10K.
