A Framework for Multiperspective Rendering
نویسندگان
چکیده
We present a framework for the direct rendering of multiperspective images. We treat multiperspective imaging systems as devices for capturing smoothly varying set of rays, and we show that under an appropriate parametrization, multiperspective images can be characterized as continuous manifolds in ray space. We use a recently introduced class of General Linear Cameras (GLC), which describe all 2D linear subspaces of rays, as primitives for constructing multiperspective images. We show GLCs when constrained by an appropriate set of rules, can be laid out to tile the image plane and, hence, generate arbitrary multiperspective renderings. Our framework can easily render a broad class of multiperspective images, such as multiperspective panoramas, neocubist style renderings, and faux-animations from still-life scenes. We also show a method to minimize distortions in multiperspective images by uniformly sampling rays on a sampling plane even when they do not share a common origin.

Multiperspective Modeling and Rendering Using General Linear Cameras
Abstract. We present a General Linear Camera (GLC) model that unifies many previous camera models into a single representation. The GLC model is capable of describing all perspective (pinhole), orthographic, and many multiperspective (including pushbroom and two-slit) cameras, as well as epipolar plane images. It also includes three new and previously unexplored multiperspective linear cameras....
متن کاملMultiperspective Imaging for Automated Urban Visualization a Dissertation Submitted to the Department of Electrical Engineering and the Committee on Graduate Studies of Stanford University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy
Traditional perspective images (such as those produced by a typical camera) cannot consistently display detail across all parts of an entire city block. It is inevitable that detail is lost in areas of the scene most distant from the camera. A multiperspective image generated from a collection of photographs or a video stream can be used to effectively summarize long, roughly planar scenes such...
متن کاملMultiperspective Distortion Correction Using Collineations
We present a new framework for correcting multiperspective distortions using collineations. A collineation describes the transformation between the images of a camera due to changes in sampling and image plane selection. We show that image distortions in many previous models of cameras can be effectively reduced via proper collineations. To correct distortions in a specific multiperspective cam...
متن کاملAn Efficient System for Multi-perspective Imaging and Volumetric Shape Analysis
We present a high performance system for efficient multiperspective image analysis on very large image datasets, implemented as a customized extension of the Active Data Repository (ADR) object-oriented framework. The resulting system provides a flexible framework for handling multiperspective video sequences in any parallel or distributed computing environment that can support ADR. We have emp...
متن کاملPLG2: Multiperspective Process Randomization with Online and Offline Simulations
The evaluation of process mining algorithms requires, as any other data mining task, the availability of large amount of (real-world) data. Despite the increasing availability of such datasets, they are affected by many limitations: in primis, the absence of a “gold standard” (i.e., the reference model). This work extends an approach already available in the literature for the generation of ran...
