ACTIVE SHAPE MODEL-BASED LIP SHAPE ESTIMATION METHOD AND SYSTEM USING MOUTH MAP

摘要

The present invention relates to an active form model based lip shape estimation method and system using a mouth map and, more desirably, comprises: a step in which a face detection unit detects a face area within an image inputted from the outside; a step in which a mouth map conversion unit converts a lip area of the primary form through the mouth map and produces one or more landmarks by overlapping the lip area of the primary form on the upper side of the lip area in the detected face area; a step in which a position search unit searches an optimum position to produce an active form model regarding the landmark; a step in which an active form model production unit produces the active form model regarding the landmark by moving the landmark to the searched optimum position; a step in which a principal component display unit displays principal component information by the active form model by arranging the active form model regarding at least one landmark; and a step in which an image display unit expresses the active form model regarding the landmark as an image and estimates a lip shape within the inputted image. By the composition, the active form model based lip shape estimation method system using the mouth map of the present invention can obtain a mouth map from a color image by using the mouth map which accentuates a read area such as a lip, etc. by using chrominance components regarding a face in an image or a part of it and can accurately estimate a lip shape by applying the mouth map to the active form model.
