摘要： System and method for improving video encoding and/or video decoding. In embodiments, a video encoding pipeline includes a main encoding pipeline that compresses source image data corresponding with an image frame by processing the source image data based at least in part on encoding parameters to generate encoded image data. Additionally the video encoding pipeline includes a machine learning block communicatively coupled to the main encoding pipeline, in which the machine learning block analyzes content of the image frame by processing the source image data based at least in part on machine learning parameters implemented in the machine learning block when the machine learning block is enabled by the encoding parameters; and the video encoding pipeline adaptively adjusts the encoding parameters based at least in part on the content expected to be present in the image frame to facilitate improving encoding efficiency.

摘要： Systems, methods, and instrumentalities are disclosed relating to intra prediction of a video signal based on mode-dependent subsampling. A block of coefficients associated with a first sub block of a video block, one or more blocks of coefficients associated with one or more remaining sub blocks of the video block, and an indication of a prediction mode for the video block may be received. One or more interpolating techniques, a predicted first sub block, and the predicted sub blocks of the one or more remaining sub blocks may be determined. A reconstructed first sub block and one or more reconstructed remaining sub blocks may be generated. A reconstructed video block may be formed based on the prediction mode, the reconstructed first sub block, and the one or more reconstructed remaining sub blocks.

摘要： Systems and methods are disclosed for image signal processing. For example, methods may include receiving a current image of a sequence of images from an image sensor; combining the current image with a recirculated image to obtain a noise reduced image, where the recirculated image is based on one or more previous images of the sequence of images from the image sensor; determining a noise map for the noise reduced image, where the noise map is determined based on estimates of noise levels for pixels in the current image, a noise map for the recirculated image, and a set of mixing weights; recirculating the noise map with the noise reduced image to combine the noise reduced image with a next image of the sequence of images from the image sensor; and storing, displaying, or transmitting an output image that is based on the noise reduced image.

摘要： Techniques and configurations for compression of image data in a progressive, lossless manner are disclosed. In an example, three-dimensional medical images may be compressed and decompressed with high-speed operations, through a compression technique performed on a cube (chunk) of voxels that includes generating a subsampled or filtered cube of voxels, and generating and optimizing a delta data set between the cube of voxels and the subsampled cube of voxels. This optimized delta data set is operable with a decompression technique to losslessly recreate the cube of voxels. Further, the compression technique may be progressively performed with multiple iterations, to allow multiple lower resolution versions of the images prior to loading or receiving the entire compressed data that is reconstructable in a lossless form. Use of this technique may result in dramatically reduced time to first image when visualizing 3D images and performing image data transfers.

摘要： To enable a receiving side to appropriately perform processing of obtaining display image data from transmission video data having a predetermined photoelectric conversion characteristic. Input video data is processing and transmission video data having a predetermined photoelectric conversion characteristic is obtained. Encoding processing is applied to the transmission video data and a video stream is obtained. A container of a predetermined format, including the video stream, is transmitted. Information indicating a photoelectric conversion of the input video data is inserted into the video stream and/or the container.

摘要： In communication applications, aggregate source image data at a transmitter exceeds the data that is needed to display a rendering of a viewport at a receiver. Improved streaming techniques that include estimating a location of a viewport at a future time. According to such techniques, the viewport may represent a portion of an image from a multi-directional video to be displayed at the future time, and tile(s) of the image may be identified in which the viewport is estimated to be located. In these techniques, the image data of tile(s) in which the viewport is estimated to be located may be requested at a first service tier, and the other tile in which the viewport is not estimated to be located may be requested at a second service tier, lower than the first service tier.
