Automatic 3D view Generation from a Single 2D Image for both Indoor and Outdoor Scenes

Image based video generation paradigms have recently emerged as an interesting problem in the field of robotics. This paper focuses on the problem of automatic video generation of both indoor and outdoor scenes. Automatic 3D view generation of indoor scenes mainly consist of orthogonal planes and outdoor scenes consist of vanishing point. The algorithm infers frontier information directly from the images using a geometric context-based segmentation scheme that uses the natural scene structure. The presence of floor is a major cue for obtaining the termination point for the video generation of the indoor scenes and vanishing point plays an important role in case of outdoor scenes. In both the cases, we create the navigation by cropping the image to the desired size upto the termination point. Our approach is fully automatic, since it needs no human intervention and finds applications, mainly in assisting autonomous cars, virtual walk through ancient time images, in architectural sites and in forensics. Qualitative and quantitative experiments on nearly 250 images in different scenarios show that the proposed algorithms are more efficient and accurate.
