Abstract Skin color detection is an important problem in computer vision. A new elliptical model based on KL transform for skin color detection is proposed in this paper. As to the proposed algorithm, firstly, the training skin color samples are made to distribute uniformly, then the elliptical boundary equation of skin color region is attained by means of KL transform. This method proves to be simple and intuitive. The experimental results on the images taken under a wide range of different environment demonstrate its efficiency and its clear improvement over the method based on explicit skin region boundary and single Gaussian model.
