Abstract: A procedure to calibrate a depth-disparity mapping for a plenoptic imaging system. In one aspect, one or more test objects located at known field positions and known depths are presented to the plenoptic imaging system. The plenoptic imaging system captures plenoptic images of the test objects. The plenoptic images include multiple images of the test objects captured from different viewpoints.

Since the field positions and depths of the test objects are known, a mapping between depth and disparity as a function of field position can be determined.

Abstract: Techniques for selecting a view of a video are described for videos having multiple views of a real-world scene that are captured simultaneously. When playback of a video is initiated, an object of interest is identified and tracked by automatically switching between multiple views of the video in order to maintain the object in view within a viewport as the object moves between the multiple views. A user input may be received at a scrub bar of the viewport, prompting generation of a thumbnail preview of the video based on a selected view of the video and a time of the video relating to the user input. The correction may be based on a view that is currently displayed in the viewport.

Abstract: A lossy compression method optimizes bandwidth and storage for a security surveillance network. An appliance on a local network attached to event capture terminals transforms image files into a key frame and at least one subsequent frame. Decompression combines a subsequent frame with its key frame to provide an image with graduated resolution/noise clutter. A camera records, and forwards a plurality of image files compatible with JPEG encoding. Key frames are selected from among the plurality of image files. A configurable low pass filter is reset for each train of a key frame and its subsequent frame or frames. Each low pass filter is selectively applied to each pixel block within a subsequent frame. The transformation operates on coefficients of frequency bins. Meta data enables decompression of a single subsequent frame by reversing some of the transformations to provide a JPEG compatible file having selectively reduced resolution or noise clutter.

Abstract: A method for processing High Dynamic Range (HDR) video in order to improve the perceived visual quality of encoded content. An encoder receives a n original image, wherein a contrast analysis is performed on said original image in order to highlight potential problematic areas. The original image is reduced to a decreased bit depth image in order to compute a predicted image, wherein the predicted image is then magnified to an increased bit depth image. A residual image is then computed from the original image and the increased bit depth image, and the residual image is transformed into a frequency signal. Quantized coefficients determined through the contrast analysis are then applied to the frequency signal to produce a reduced frequency signal. The encoder then inserts high-frequency components into the reduced frequency signal before encoding a compressed image from the reduced frequency image and the predicted image.

In one embodiment, a content caching controller associated with a content server differentiates content requests based on content attributes such as the requested codec format (e.g., MPEG or Windows Media), resolution, bitrate, and/or encryption type or security environment.

The content server also speculatively caches the transformed content locally, so that a future request for the same content with the same attributes can be filled by transferring without the intermediate transformation step. The controller allows the network operator to optimize use of available storage and transcoding resources.
