Non-photorealistic Tour into Panorama

In this paper, we describe a system NP-TIP ( Non-Photorealistic Tour Into Panorama ). It provides a simple non-photorealistic scene model in which users can freely walk through and obtain enjoyable and real-time artistic experience. In NP-TIP, firstly we design a new algorithm for fast converting a photo or image to a synthesized painting following the painting style of an example image. By treating painting styles as sample textures, we reduce the problem of learning an example painting to that of texture synthesis, which improves the speed of non-photorealistic rendering. Secondly, we propose a new modeling scheme for TIP based on the cubic panorama, which not only overcomes the disadvantage of fixed viewpoint in browsing panorama, but also models easily and computes simply. According to users' selection from example paintings of different artistic style, NP-TIP can provide stylized interactive and real-time panoramic walkthrough of scenes.
