Abstract: The present disclosure relates to methods and devices for video or frame processing including an apparatus, e.g., a video or frame processor. In some aspects, the apparatus may receive a video stream including a plurality of frames, each of the plurality of frames including luminance information. The apparatus may also perform a histogram analysis on the luminance information for each of the plurality of frames. Additionally, the apparatus may determine whether a difference between the luminance information for each of the plurality of frames and a current luminance distribution is greater than a perceptual threshold. The apparatus may also calculate an updated tone mapping configuration based on the luminance information for a frame when the difference between the luminance information for the frame and the current luminance distribution is greater than the perceptual threshold.

Abstract: A method of content compression including receiving a first block of samples including at least a first sample and a second sample, calculating a predictor value for the first block of samples, calculating a residual between the predictor value and the first sample, quantizing the residual to generate a quantized residual, de-quantizing the quantized residual to generate a de-quantized residual, reconstructing the first sample using the de-quantized residual and the predictor value to generate a first reconstructed sample, calculating an error value based on the first sample and the first reconstructed sample, and modifying the second sample by the error value.

Abstract: Provided are systems and methods for used fixed-point instead of floating point techniques in order to calculate various parameters for coding video data, including target rate, QP adjustment, buffer fullness, a Lagrangian parameters for a bitrate, and/or a Lagrangian parameter for the fullness of the buffer. By determining one or more of the parameters using fixed-point, hardware implementation costs may be decreased.

Abstract: The present disclosure relates to methods and apparatus for image processing. The apparatus can generate object mask information for one or more objects in a first image of a plurality of images in a scene. In some aspects, the first image can be at least one of a downscaled image, a down-sampled image, or a low resolution image. The apparatus can also determine one or more object classifications of the first image based on the generated object mask information. Additionally, the apparatus can identify a modification to at least one of the one or more object classifications based on a second image of the plurality of images in the scene. In some aspects, the apparatus can adjust or maintain the one or more object classifications based on the identified modification to at least one of the one or more object classifications.

Abstract: Techniques of this disclosure may include processing one or more regions-of-interest (ROI) of an input image through a model of a display processor, calculating a first data integrity check value on the one or more ROI of the input image after processing through the model, processing the input image by the display processor, calculating a second data integrity check value on the one or more ROI by the display processor after the display processor processes the input image, comparing the first data integrity check value to the second data integrity check value, and generating an interrupt if the comparison indicates that the first data integrity check value and the second data integrity check value do not match.

Abstract: In an example, a method for image processing may include inputting a first pixel value corresponding to a first pixel of an image into a LUT. The LUT may map one or more LUT input values to one or more LUT output values. The first pixel value may correspond to a first LUT input value that maps to a first LUT output value in the LUT. The first pixel may include one or more pixel values. The method may include generating a noise value for the first LUT input value. The method may include generating a first interpolated LUT output value for the first LUT input value based on the noise value. The method may include transforming the image into a transformed image using the first interpolated LUT output value.

Abstract: A device includes a memory and at least one processor coupled to the memory. The at least one processor is configured to: generate, an original image for display, store the original image in the memory, adjust color tone of the original image by suppressing blue energy of a color spectrum of the original image to produce an adjusted image, store the adjusted image in the memory, and output the adjusted image for display.

Abstract: Methods and apparatus for graphics processing, such as producing a smooth transition between images of different dynamic ranges (e.g., Standard Dynamic Range (SDR) images and High Dynamic Range (HDR) images). An example method generally includes using a high frame rate during a transition period to allow properties of images to incrementally vary. The properties may include brightness (i.e., luminance), color gamut, tone mapping, among others. For example, during the transition period, a subset of HDR images are displayed at a second frame rate (e.g., 120 Hz) higher than a frame rate based on the HDR images (e.g., 30 Hz). Simultaneously, a brightness level (as well as other aspects) of the display panel is adjusted incrementally from an SDR brightness level to an HDR brightness level during the transition time period over the subset of the HDR images.
