    Abstract: Techniques are described for performing multi-stage image classification. For example, multi-stage image classification can comprise a first classification stage and a second classification stage. The first classification stage can determine an overall classification for an input image (e.g., based on a relative entropy result calculated for the input image). The second classification stage can be performed by dividing the image into a plurality of blocks and classifying individual blocks, or groups of blocks, based on a classification model that is specific to the overall classification of the image determined in the first classification stage.

    Abstract: An invention is disclosed for conducting a remote presentation session with a client that uses a web browser to conduct the session. The client previously received browser-native program code that executes within a runtime environment of the web browser. The browser-native program code instantiates a remote presentation client executing within a runtime environment of the web browser. The server generates graphics encoded according to a remote presentation protocol and sends them to the remote presentation client for display in the web browser. The client captures user input at the web browser and sends it to the remote presentation client, which encodes it with the remote presentation protocol and sends it to the server to be processed.

    Abstract: Innovations in the area of filtering in and around high chroma resolution regions of output pictures are presented. For example, a video processing tool applies a recovery filter in a high chroma resolution region of an output picture, which compensates for anti-aliasing filtering previously performed during chroma sub-sampling, but skips application of the recovery filter in a low chroma resolution region of the output picture. Or, a video processing tool applies a deblocking filter to chroma sample values at a boundary between a low chroma resolution region and high chroma resolution region in the output picture, which can mitigate perceptible distortion at the boundary. Or, a video processing tool selectively applies a deringing filter to chroma sample values in a high chroma resolution region of the output picture, which can mitigate perceptible distortion due to low quality coding of high chroma resolution details.

    Abstract: Variations of rho-domain rate control for video encoding or other media encoding are presented. For example, in some of the variations, an encoder sets a rho value for a unit of media based at least in part on a bit allocation for the unit. The encoder also computes transform coefficients for the unit using a frequency transform having multiple location-dependent scale factors, sets a value of quantization parameter (“QP”) for the unit using a mapping of QP values to rho values, and uses the value of QP for the unit during quantization of the transform coefficients of the unit. When the QP-rho mapping is determined, a location-independent scale factor that approximates the multiple location-dependent scale factors is used and/or certain scaling operations are integrated, which reduces computational complexity while still supporting accurate rate control decisions. Implementations of such variations of rate control can exploit opportunities for caching and parallel computation.

    Abstract: A GPU loads point sprites that represent coded blocks of transform coefficients of one or more frames encoded in a bitstream and loads a transform kernel as a transform kernel texture. The GPU constructs an output frame using an inverse transform on the coded blocks of transform coefficients by transforming the point sprites with the transform kernel texture and by optionally dequantizing the point sprites. A single render pass may be used in which the rasterization formula performs the inverse transform and optionally dequantization. To preserve bandwidth, a CPU may refrain from sending the GPU at least some zero valued transform coefficients for the point sprites. Also, to reduce processing, the transform coefficients can remain in a zig-zag arrangement. The transform kernel texture used in the decoding can correspond to a modified version of the basis matrices used to encode the frame, which compensates for the zig-zag arrangement.
