Abstract

Colored objects are represented by digitized color histograms which are used for the segmentation of digital color images. In this case, the binary values of the color histograms correspond to the decision as to whether a pixel can or cannot belong to a given object segment. Model-based parameterizations of these color histograms are preferred for the efficient execution of the segmentation. In particular, they permit adaptation of the color histograms to temporally varying lighting conditions with acceptable expense.
