  • Publication number: 20160292825
    Abstract: A method of image processing includes receiving data representative of image at a computing device. The method further includes generating a first modified image by changing a luma channel of the image according to a first function. The method further includes generating a second modified image by changing the luma channel of the image according to a second function. The method further includes determining weights based on values of pixels in the image. The method further includes generating a refined image by combining first pixel values of the first modified image and second pixel values of the second modified image based on the weights.

  • Publication number: 20150063694
    Abstract: Techniques are described for combining two or more images that are taken with varying brightness degrees to generate a composite image. In one embodiment, at least two weight masks are generated based on one or more characteristics of the two or more images. A first image A first weight mask is used to combine color channels of one or more pixels of the two or more images and a second weight mask is used to combine intensity channels of the one or more pixels of the two or more images.

  • Publication number: 20150063718
    Abstract: Techniques are described for enhancing quality of a first image that is captured in a low-light environment. In one embodiment, a second image is generated by brightening a plurality of pixels in the first image based on a predefined criteria. A third image is generated using an edge-preserving noise reduction algorithm based on the second image. Further, a composite image is generated by obtaining a weighted average of the first image and the third image. The techniques described herein can be applied to an image and/or to each frame of a video that is captured in low-light environments.

  • Patent number: 8237708
    Abstract: A novel layered orthographic representation of the light field, comprising a set of 3-D orientations, each orientation having an associated depth direction and two sampling directions, each such orientation being associated with a set of planar grids normal to the depth direction and containing grid points evenly sampled along the sampling directions, each grid containing orthographic samples of the light field intercepting that grid point in the direction of the associated depth direction. Information of the geometric structure is similarly stored in depth field format at these sample points.
