Abstract(in English) | We have developed a system that detects the location of origami paper from single camera images and supports foldings in real-time. This paper proposes an approach to appropriately point out the user's mistaken folding. First, a method of detecting the mistakes by using the progress of the folding and the distance between the user's origami shape and the correct shape is described. However, in this system, shadows and occlusion caused by user's hands frequently occur, so it is not possible to obtain the accurate shape of origami paper in the all time. Therefore, an anomaly detection problem among shape variation of origami paper observed as time series data is solved based on machine learning. The effectiveness of the proposed method is demonstrated by experiments using a one-class support vector machine (one-class SVM). |
