Abstract: Systems and techniques are provided for generating disparity information from two or more images. For example, a process can include obtaining first disparity information corresponding to a pair of images, the pair of images including a first image of a scene and a second image of the scene. The process can include obtaining confidence information associated with the first disparity information. The process can include processing, using a machine learning network, the first disparity information and the confidence information to generate second disparity information corresponding to the pair of images. The process can include combining, based on the confidence information, the first disparity information with the second disparity information to generate a refined disparity map corresponding to the pair of images.

Abstract: Certain aspects of the present disclosure provide techniques for global motion modeling. Embodiments include receiving a first image and a second image from a camera attached to a moving object. Embodiments include identifying a pixel in the first image. Embodiments include determining, based on one or more parameters associated with the camera, a vector representing a range of locations in which a real-world point corresponding to the pixel is likely to be found in the second image, wherein the parameters associated with the camera comprise: a first parameter related to a location of the camera relative to a ground surface; a second parameter related to motion of the moving object; and a third parameter related to an orientation of the camera relative to the ground surface. Embodiments include determining, using the vector, a location of the real-world point in the second image.

Abstract: A device includes a decoder that includes a spatial prediction engine, a temporal prediction engine, a reconstruction engine, and a decoded picture buffer. The device also includes a controller configured to cause the decoder to, in a base resolution mode, reconstruct a base resolution version of a block of a frame using the reconstruction engine and at least one of the spatial prediction engine or the temporal prediction engine. The controller is also configured to cause the decoder to, in an enhanced resolution mode, generate an enhanced resolution version of the block using the reconstruction engine and the at least one of the spatial prediction engine or the temporal prediction engine.

Abstract: A device includes one or more processors configured to obtain a bitstream corresponding to an encoded version of an image frame. The one or more processors are also configured to, based on determining that the bitstream includes a virtual reference frame usage indicator, generate a virtual reference frame based on synthesis support data included in the bitstream. The one or more processors are further configured to generate a decoded version of the image frame based on the virtual reference frame.
