Generation and use of a 3D radon image

Certain aspects relate to systems and techniques for efficiently recording captured plenoptic image data and for rendering images from the captured plenoptic data. The plenoptic image data can be captured by a plenoptic or other light field camera. In some implementations, four dimensional radiance data can be transformed into three dimensional data by performing a Radon transform to define the image by planes instead of rays. A resulting Radon image can represent the summed values of energy over each plane. The original three-dimensional luminous density of the scene can be recovered, for example, by performing an inverse Radon transform. Images from different views and/or having different focus can be rendered from the luminous density.

Multi-perspective stereoscopy from light fields

Methods and systems for generating stereoscopic content with granular control over binocular disparity based on multi-perspective imaging from representations of light fields are provided. The stereoscopic content is computed as piecewise continuous cuts through a representation of a light field, minimizing an energy reflecting prescribed parameters such as depth budget, maximum binocular disparity gradient, desired stereoscopic baseline. The methods and systems may be used for efficient and flexible stereoscopic post-processing, such as reducing excessive binocular disparity while preserving perceived depth or retargeting of already captured scenes to various view settings. Moreover, such methods and systems are highly useful for content creation in the context of multi-view autostereoscopic displays and provide a novel conceptual approach to stereoscopic image processing and post-production.

Still-image extracting method and image processing device for implementing the same

A still-image extracting method is disclosed. Frames of an object are extracted as still images from a moving image stream chronologically continuously captured by a camera. The camera moves relative to the object. First frames are extracted from the moving image stream. Image capture times of the extracted first frames are obtained. Image capture positions of the camera at the image capture times of the first frames are identified based on the first frames. Image capture times of the frames captured at image capture positions spaced at equal intervals are estimated based on both the image capture positions, identified by the first frames, of the camera and the obtained image capture times. Second frames at the estimated image capture times are extracted as frames captured and obtained at image capture positions spaced apart at equal intervals from the moving image stream.
