Automatic model-based anchorperson detection

A model-based anchorperson detection algorithm is discussed for automatic news video indexing. Anchorperson pattens are modeled with respect to their color and shape features and the detection problem is decomposed into a color-based face region detection and a model-based head-and-shoulder shape detection problem. Experimental results are reported on actual NBC nightly news with high detection rates.
