Abstract: Methods, processes, and systems are presented for adaptive loop filtering in coding and decoding high dynamic range (HDR) video.

Abstract: Methods for the chroma reshaping of high-dynamic range (HDR) signals are presented. For each input pixel, a first scaler is generated based on the pixel luminance and a luma-based chroma reshaping (LCR) function. A second scaler is generated based on a saturation-based chroma reshaping (SCR) function and the saturation value of the pixel. A cascaded scaler is generated by multiplying the first scaler with the second scaler. Reshaped chroma values are generated by multiplying the input chroma values with the cascaded scaler. The characteristics of preferred LCR and SCR functions are discussed. Inverse decoding methods based on chroma-reshaping metadata that define the LCR and SCR functions are also described.

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.

Abstract: The disclosure relates to handling nuisance in teleconference system. An endpoint device (400) for use in a teleconference includes an acquiring unit (401), a judging unit (402), a controller (403) and a processing unit (404). The acquiring unit acquires a media stream for presentation in the teleconference, and receives information from another device. The information includes a first estimation on whether the media stream is a nuisance to the teleconference. As the nuisance to a teleconference, audio or video signals are perceived by users as actually not relevant to the conference session or causing unpleasant feeling or confusion. The judging unit decides whether the media stream is the nuisance at least based on the information. The controller controls the processing of the media stream to degrade or suppress the presentation of the media stream in case that the media stream is decided as the nuisance. The processing unit processes the media stream under the control of the controller.

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.
