Mixture models with skin and shadow probabilities for fingertip input applications ?
Moving skin regions and shadows are detected. Skin and shadow probabilities are integrated into the mixture models. Learning rates are adjusted by the skin and shadow probabilities. Mandarin Phonetic Symbol (MPS) combination recognition algorithm is designed. Single fingertip virtual keyboard system is implemented.
