  • Patent number: 11659133
    Abstract: Embodiments of the disclosure provided herein generally relate to methods and video system components that have integrated background differentiation capabilities that allow for background replacement and/or background modification. In some embodiments, undesired portions of video data generated in a video environment are separated from desired portions of the video data by taking advantage of the illumination and decay of the intensity of electromagnetic radiation, provided from an illuminator, over a distance. Due to the decay of intensity with distance, the electromagnetic radiation reflected from the undesired background has a lower intensity when received by the sensor than the electromagnetic radiation reflected from the desired foreground. The difference in the detected intensity at the one or more wavelengths can then be used to separate and/or modify the undesired background from the desired foreground for use in a video feed.

  • Patent number: 10614854
    Abstract: Provided is a system for efficiently creating snippets or clips from media assets without re-encoding the entire portion of already encoded media content falling within the snippet boundaries. The system partitions and encodes the original media asset as set of slices with each slice encoding a different temporal chunk of the media asset. The system identifies a first slice that encodes a duration of the media asset spanning the snippet start time, and a second slice that encodes a duration of the media asset spanning the snippet end time. The system produces a snippet start slice from decoding, clipping, and re-encoding the first slice and a snippet end slice from decoding, clipping, and re-encoding the second slice. The system generates the snippet from the snippet start slice, an unmodified subset of the set of slices between the first slice and the second slice, and the snippet end slice.

  • Patent number: 8085990
    Abstract: The claimed subject matter relates to a computer-implemented architecture that can generate a map. The map can be a hybrid between an orthographic projection map and street-side images, thus including useful aspects from both types of representations. For example, an orthographic projection map is very effective at presenting global relationships among the features of the map but not effective at presenting local detail. In contrast, street -side images show excellent detail but do not convey the global information of an orthographic projection map. The hybrid map can thus provide a richer set of information than conventional maps and can also display objects/features of the hybrid map in multiple perspectives simultaneously on a single representation that is printable.

  • Patent number: 7755645
    Abstract: Systems and methods provide object-based image inpainting. The object-based inpainting can recover part of a missing object or can synthesize visual objects that are entirely missing. In one implementation, an exemplary system generates a target visual object to be inpainted into an image, by geometrically matching key features with a model visual object that can be selected from the same or another image. Borders of the target object are refined through pixel-based contour deformation and textures for the target object are obtained either by pixel interpolation or by patch-based modeling of pre-existing texture in the image. Graph-cut segmentation rectifies image overlap as the target object is embedded in the image. Poisson editing filters visual seams, and edge filling completes visual gaps around the border of the target object.

  • Patent number: 7548644
    Abstract: A digital image processing apparatus for applying pixel-based color correction to an input image to generate an output image is described herein. The apparatus includes color correction logic arranged to provide two or more color correction processes. Each color correction process has a respective associated locus in a color space and a respective associated color mapping operation. The color correction processes are arranged as a succession of processes so that the results of a color correction process form the input to a next such process in the succession. Each color correction process is operable to detect whether each pixel lies within the respective locus in color space and, if so, to apply the color mapping operation to that pixel. Each color correction process after the first process in the succession is configured to inhibit color mapping in respect of the loci associated with previous processes in the succession.
