Abstract: A method and system for adaptively mixing video components with graphics/UI components, where the video components and graphics/UI components may be of different types, e.g., different dynamic ranges (such as HDR, SDR) and/or color gamut (such as WCG). The mixing may result in a frame optimized for a display device's color space, ambient conditions, viewing distance and angle, etc., while accounting for characteristics of the received data. The methods include receiving video and graphics/UI elements, converting the video to HDR and/or WCG, performing statistical analysis of received data and any additional applicable rendering information, and assembling a video frame with the received components based on the statistical analysis. The assembled video frame may be matched to a color space and displayed. The video data and graphics/UI data may have or be adjusted to have the same white point and/or primaries.

Abstract: Methods are described for encoding and decoding blocks of image data using intra block copying (IBC). A source block for intra block copying is selected from a source region of a current image that is closer to the current block than a threshold, wherein the source region does not include a portion of the current image that is further from the current block than the threshold.

Abstract: A video enhancement processing system improves perceptual quality of video data with limited processing complexity. The system may perform spatial denoising using filter weights that may vary based on estimated noise of an input image. Specifically, estimated noise of the input image may alter a search neighborhood over which the denoising filter operates, may alter a profile of weights to be applied based on pixel distances and may alter a profile of weights to be applied based on similarity of pixels for denoising processes. As such, the system finds application in consumer devices that perform such enhancement techniques in real time using general purpose processors such as CPUs or GPUs.
