background: historically, operating room (or) has always been considered as a stand-alone trusted platform for surgical education and training.however, concerns about financial constraints, quality control, and patient safety have urged the surgical educators to develop more cost-effective, surgical educational platforms that can be employed outside the or. furthermore, trained surgeons need to...

Interest in view interpolation and novel view synthesis is growing. In this paper we show how dense correspondence can be found between needle-maps generated using shape-from-shading, which in turn can be used to generate new needle-maps. From these we can produce novel intermediate views, and also estimates of how each intermediate view would look under different lighting conditions. The appro...

We propose a multiple view layered representation for tracking and segmentation of multiple objects in a scene. Existing layered approaches are dominated by the single view case and generally exploit only motion cues. We extend this to integrate static, dynamic and structural cues over a pair of views. The goal is to update coherent correspondence information sequentially, producing a multi-obj...

The topic of representation, recovery and manipulation of three-dimensional (3D) scenes from two-dimensional (2D) images thereof, provides a fertile ground for both intellectual theoretically inclined questions related to the algebra and geometry of the problem and to practical applications such as Visual Recognition, Animation and View Synthesis, recovery of scene structure and camera ego-moti...

Multiview video applications are getting emerging in the recent years by its 3D and free-view-point perception functionalities. To support smooth viewpoint switching, virtual view synthesis is required. However, the color information between each view is different due to the difference between multiview cameras. Further, the complexity and the corresponding bandwidth grow up dramatically with n...

Accurate and efficient monitoring of dynamically changing environments is one of the most important requirements for visual surveillance systems. This paper describes the development of an integrated system for this monitoring purpose. The system consists of multiple omni-directional vision sensors and was developed to address two specific surveillance tasks: (1) Robust tracking and profiling o...

The encoding of both texture and depth maps of a set of multiview images, captured by a set of spatially correlated cameras, is important for any 3D visual communication systems based on depth-image-based rendering (DIBR). In this paper, we address the problem of efficient bit allocation among texture and depth maps of multi-view images. We pose the following question: for chosen (1) coding too...

Acknowledgments I would like to thank my advisor, Prof. Shimon Ullman, for his devoted guidance and helpful suggestions, for always being available and the extensive knowledge I acquired from him. I would also like to thank my wife Hagit for her encouragement, support, and belief in me, and my parents and family for all their support. Finally, I would like to thank my friends in the Weizmann In...

This paper presents a novel approach to provide immersive free navigation with 6 Degrees of Freedom in real-time for natural and virtual scenery, both static dynamic content. Stemming from the state-of-the-art Depth Image-Based Rendering OpenGL pipeline, this new View Synthesis method achieves at up 90 FPS can take any number input views their corresponding depth maps as priors. Video content b...

We present a new method for rendering novel images of exible 3D objects from a small number of example images in correspondence. The strength of the method is the ability to synthesize images whose viewing position is signi cantly far away from the viewing cone of the example images (\view extrapolation"), yet without ever modeling the 3D structure of the scene. The method relies on synthesizin...
