This paper presents a 3D stereoscopic TIP (Tour Into Picture) for Korean classical paintings being composed of persons, boat, and landscape. Unlike conventional TIP methods providing 2D image or video, our proposed TIP can provide users with 3D stereoscopic contents. Navigating a picture with stereoscopic viewing can deliver more realistic and immersive perception. The method firstly makes input data being composed of foreground mask, background image, and depth map. The second step is to navigate the picture and to obtain rendered images by orthographic or perspective projection. Then, two depth enhancement schemes such as depth template and Laws depth are utilized in order to reduce a cardboard effect and thus to enhance 3D perceived depth of the foreground objects. In experiments, the proposed method was tested on 'Danopungjun' and 'Muyigido' that are famous paintings made in Chosun Dynasty. The stereoscopic animation was proved to deliver new 3D perception compared with 2D video.

This paper describes a 3-DTIP(3-D Tour Into Picture) using depth map for a Korean classical painting being composed of persons and landscape. Unlike conventional TIP methods providing 2-D image or video, our proposed TIP can provide users with 3-D stereoscopic contents. Navigating inside a picture provides more realistic and immersive perception. The method firstly makes depth map. Input data consists of foreground object, background image, depth map, foreground mask. Firstly we separate foreground object and background, make each of their depth map. Background is decomposed into polygons and assigned depth value to each vertexes. Then a polygon is decomposed into many triangles. Gouraud shading is used to make a final depth map. Navigating into a picture uses OpenGL library. Our proposed method was tested on "Danopungjun" and "Muyigido" that are famous paintings made in Chosun Dynasty. The stereoscopic video was proved to deliver new 3-D perception better than 2-D video.

The free viewpoint video delivers an active contents where users can see the images rendered from the viewpoints chosen by them. Its applications are found in broad areas, especially museum tour, entertainment and so forth. As a new free-viewpoint application, this paper presents a stereoscopic free-viewpoint TIP (Tour Into Picture) where users can navigate the inside of a single image controlling a virtual camera and utilizing depth data. Unlike conventional TIP methods providing 2D image or video, our proposed method can provide users with 3D stereoscopic and free-viewpoint contents. Navigating a picture with stereoscopic viewing can deliver more realistic and immersive perception. The method uses semi-automatic processing to make foreground mask, background image, and depth map. The second step is to navigate the single picture and to obtain rendered images by perspective projection. For the free-viewpoint viewing, a virtual camera whose operations include translation, rotation, look-around, and zooming is operated. In experiments, the proposed method was tested eth 'Danopungjun' that is one of famous paintings made in Chosun Dynasty. The free-viewpoint software is developed based on MFC Visual C++ and OpenGL libraries.

Image-based rendering is an approach to generate realistic images in real-time without modeling explicit 3D geometry. Especially, owing to its simplicity, TIP(Tour Into the Picture) is preferred to constructing a 3D background scene. Because existing TIP methods have a limitation in that they lack geometrical information, we can not expect a accurate scene if the viewpoint is far from the origin of the TIP. In this paper, we propose the method of constructing a virtual environment of a wide area by blending multiple TIP images. Firstly, we construct multiple TIP models of the virtual environment. Then we interpolate foreground and background objects respectively, to generate a smooth navigation image. The method proposed here can be applied to various industry applications, such as computer game, 3D car navigation, and so on.

Objective of this study is to develop a 3D car navigation system that shows the driving direction to a destination through real-time 3-D panoramic views of the route. For the purpose, a new searching process was established to find the optimal driving direction based on the driver's current location and the real-time traffic situation and the TIP (tour into the picture) method was extended to implement a wide virtual environment. A virtual environment was built up by applying the extended TIP method to the panoramic images taken at a constant distance from a real road, and then, displayed 3-D navigation as clear as the real images. The car navigation system developed in this study provides the optimal driving direction and real-time traffic situation using 2-D navigation module and 3D navigation module.

However, TP has a limitation that a viewpoint cannot go far from the origin of the TIP for the lack of geometrical information. in this paper, we propose a method to interpolating the TIP images to generate smooth and realistic navigation. We construct multiple TIP models in a wide area of the virtual environment. Then we interpolate foreground objects and background object respectively to generate smooth navigation results.

In this paper we propose the methodology for 3D background image construction in computer games. This methodology was developed based on TIP (Tour Into the Picture) using a vanishing line Proposed by Kang et at. The methodology Proposed in this study can simply implement a 3D background for a computer game with a background model which is very complex or based on a real picture. Compared to the graphics technologies generally used, the proposed methodology does not need the process of modeling elaborate 3D information of a background, and hence can display the background even on a low grade personal computer using a small reference image. TIP technology was successfully applied to the implementation of a background model for a computer game and was found to be appropriate especially for real time games.

본 논문에서는 종래의 2차원 영상의 3차원 효과 부여 기술인 TIP(Tour Into the Picture)의 결과물이 실시간 인터랙티브 콘텐츠를 생성하지 못하는 결점을 보완하고자 종래의 TIP 모델링 요소를 실시간 리모델링 할 수 있도록 모델링 요소를 변수화 하였다. 따라서, 사용자가 원근정보 및 영상 속 객체의 자유로운 이동을 수행하여 3차원 효과를 생성할 수 있으며, 기존의 그림과는 다른 새로운 영상을 만들 수도 있다. 실시간 인터랙션 기능이 추가된 결과물로서 PTIP를 제안하고 있으며, 제안하는 방법을 사용하면 실시간 인터랙티브 한 3차원 효과 컨텐츠를 제작할 순 있는 장점이 있다.

In ubiquitous computing, there is increasing demand for ubiquitous displays that react to a user's actions. We propose a method of navigating pictures on an ambient display using implicit interactions. The ambient display can identify the user and measure how far away they are using an RFID reader and ultrasonic sensors. When the user is a long way from the display, it acts as a digital picture and does not attract attention. When the user comes within an appropriate range for interaction, the display shows pictures that are related to the user and provides quasi-3D navigation using the TIP(tour into the picture) method. In addition, menus can be manipulated directly on a touch-screen or remotely using an air mouse. In an emergency, LEDs around the display flash to alert the user.

유비쿼터스 컴퓨팅 환경으로 변화됨에 따라 사용자의 묵시적인 행위에 따라 반응하면서도 주의를 지나치게 집중시키지 않는 다양한 디스플레이에 대한 요구가 증가되고 있다. 본 논문에서는 액자형 앰비언트 디스플레이 시스템을 이용하여 사용자의 위치에 따라 사진을 내비게이션 하는 방법을 제안한다. RFID 센서와 초음파 센서를 이용하여 사용자 신원 및 디스플레이와의 접근거리를 인식하고, 사용자와 디스플레이의 근접도에 따라 보여 질 영상과 인터페이스의 상세도 레벨을 자동으로 정하게 된다. 사용자가 디스플레이로부터 아주 멀리 있는 경우에는 주의를 집중시키지 않도록 단순한 그림 액자의 기능을 제공한다. 사용자가 인터랙션 가능한 영역으로 진입하면 사용자와 관련된 사진을 보여주고, 사용자의 위치에 따라 TIP(Tour Into the Picture) 방법을 이용하여 사진을 3 차원 내비게이션 할 수 있도록 하였다. 또한 터치 스크린을 이용한 메뉴의 직접적인 조작과 공중 마우스를 이용한 원격 메뉴 조작 또한 가능하도록 하였다. 뿐만 아니라 댁내의 응급 상황 정보 등을 전달 할 수 있도록 디스플레이 프레임 주위를 LED 를 이용하여 반짝일 수 있도록 설계 하였다.
