  • Content-adaptive reshaping for high dynamic range images
    Patent number: 10165275
    Abstract: A processor for forward reshaping to a target bit depth receives an input image with an input bit depth. The input luminance range is divided into luminance bands and each band is assigned a visual importance index. The output codewords at the target bit depth are divided into codeword bins and each bin is assigned to one of the luminance bands. Each codeword bin is assigned the visual importance index of the luminance band it belongs. Each bin is allocated a number of reshaped codewords according to its visual importance index and a codeword mapping function, where bins with the highest importance index are allocated more codewords than the other bins. A signal reshaping function is generated based on the allocation of codewords, and the reshaping function is applied to the input image to generate an output image in the target bit depth.

  • High precision up-sampling in scalable coding of high bit-depth video
    Patent number: 10165288
    Abstract: The precision of up-sampling operations in a layered coding system is preserved when operating on video data with high bit-depth. In response to bit-depth requirements of the video coding or decoding system, scaling and rounding parameters are determined for a separable up-scaling filter. Input data are first filtered across a first spatial direction using a first rounding parameter to generate first up-sampled data. First intermediate data are generated by scaling the first up-sampled data using a first shift parameter. The intermediate data are then filtered across a second spatial direction using a second rounding parameter to generate second up-sampled data. Second intermediate data are generated by scaling the second up-sampled data using a second shift parameter. Final up-sampled data may be generated by clipping the second intermediate data.

  • Rate control adaptation for high-dynamic range images
    Patent number: 10136133
    Abstract: A high dynamic range input video signal characterized by either a gamma-based or a perceptually-quantized (PQ) source electro-optical transfer function (EOTF) is to be compressed. Given a luminance range for an image-region in the input, for a gamma-coded input signal, a rate-control adaptation method in the encoder adjusts a region-based quantization parameter (QP) so that it increases in highlight regions and decreases in dark regions, otherwise, for a PQ-coded input, the region-based QP increases in the dark areas and decreases in the highlight areas.

  • Specifying visual dynamic range coding operations and parameters
    Patent number: 10136162
    Abstract: Coding syntaxes in compliance with same or different VDR specifications may be signaled by upstream coding devices such as VDR encoders to downstream coding devices such as VDR decoders in a common vehicle in the form of RPU data units. VDR coding operations and operational parameters may be specified as sequence level, frame level, or partition level syntax elements in a coding syntax. Syntax elements in a coding syntax may be coded directly in one or more current RPU data units under a current RPU ID, predicted from other partitions/segments/ranges previously sent with the same current RPU ID, or predicted from other frame level or sequence level syntax elements previously sent with a previous RPU ID. A downstream device may perform decoding operations on multi-layered input image data based on received coding syntaxes to construct VDR images.

  • Piecewise inter-layer prediction for signals with enhanced dynamic range
    Patent number: 10123019
    Abstract: Pixel data of a video sequence with enhanced dynamic range (EDR) are predicted based on pixel data of a corresponding video sequence with standard dynamic range (SDR) and a piecewise inter-layer predictor. The output parameters of the piecewise predictor are computed based atleast on two sets of pre-computed values and a prediction cost criterion. The first set of pre-computed values applies to all input SDR frames and comprises a set of SDR pixel values raised to one or more integer power terms. The second set of pre-computed values is frame specific and is computed based on a histogram of an input SDR frame and pixel values of the corresponding EDR frame. The pre-computed values allow for a fast iterative algorithm to identify the best pivot points for the piecewise polynomials according to a prediction cost and to solve for the coefficients of the piecewise predictor.

  • Signal Reshaping for High Dynamic Range Signals
    Publication number: 20180234704
    Abstract: In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.
