Abstract (in Japanese) (See Japanese page) 
(in English) A caricature is a medium expressing the facial features of a person briefly, and since it is used in various scenes, studies on the automatic generation of caricatures have been carried out. Among them, automatic extraction methods of facial feature points have been studied. Since the extraction precision is not necessarily stabilized and necessary information has not been completely acquired, the quality of automatically generated caricatures has not reached the level of caricatures by hand drawing yet. This paper proposes an automatic extraction method of mouth region that is robust to shooting conditions, and make the extraction accuracy stable. In addition, we aim to acquire information of the inside of mouth automatically that could not be obtained by conventional methods to improve the expressiveness of caricatures. The proposed method can reduce the influence of shooting conditions in mouth area extraction and makes the robust automatic extraction possible. The extraction accuracy is improved and it becomes possible to automatically acquire intraoral information, which improves the expression of caricatures.
