A Novel Lips Detection Method Combined Adaboost Algorithm and Camshift Algorithm

【摘要】：The lips detection has a very unique role in identification and tracking, voice recognition, lipsreading and so on. This paper proposed a new lips detection method by combined Adaboost algorithm and Camshift algorithm. First, detects the lips by the lips classification which trained by Adaboost algorithm, and marks the specific lips location with a rectangular window. Then, makes the lips color region as the tracking color tracked by Camshift algorithm, and track the lips position in the next frame. Finally, uses Adaboost algorithm to do lips detection. The new lips detect method overcomes search the entire window just use Adaboost algorithm, greatly improved the accuracy of lips detection.
