This paper proposes a Microsoft Kinect-based real-time 3D virtual dressing room system. The system has two advantages. First, by using Kinect and 3D modeling customization, the user’s real-time movement is tracked and displayed, which provides the user a realistic feeling during trying on the items virtually. Second, unlike other virtual dressing room where the user has to use it physically at the boutiques, the system can be used at home, which provides the users more convenient shopping experience. Our main goal is focusing on the garment physical movement, by different techniques, we try to make the physical movement of the garment as real as we can, because we think that the physical movement of the garment is one of the most important standard to classify a good virtual dressing system. The paper is divide into seven parts, include introduction, important techniques, system description, result and conclusion etc., also we included some related work that we have searched to improve our system.
