A new threshold selection algorithm for multidimensional feature space is proposed, and its applications to colour images are shown. This algorithm is based on tho recursive application of a simple 1-D threshold selection method (valley detection) to the conditional 1-D histograms. Although the performance of the algorithm such as convergence rate etc. is not yet evaluated, uniform colour regions are successfully extracted by the proposed algorithm for several colour images.
