Verfahren zum Detektieren eines menschlichen Gesichtes |
摘要 |
A method is provided for detecting a human face in an image, such as a sequence of images supplied by a video camera (3). The method comprises locating (17) in each image a candidate face region and analysing (18) the candidate face region for a first characteristic indicative of a facial feature. The locating step (17) may comprise detecting (S23) uniformly saturated regions of predetermined shape in a reduced resolution version of the image. The analysing step (18) may comprise selecting a single colour component (S10), forming a vertical integral projection profile and detecting (S31) an omega shape in the profile characteristic of an eye region of a face. <IMAGE> |
