    摘要： The present disclosure generally relates to a method for signaling, in a bitstream representing a LDR picture and an illumination picture both obtained from an HDR picture, both a picture/video format of a decoded version of said LDR picture, called an output LDR format, and a picture/video format of a decoded version of said HDR picture, called an output HDR format, the method comprising encoding in the bitstream a first syntax element defining the output LDR format. The method is characterized in that it further comprises encoding in the bitstream a second syntax element which is distinct from the first syntax element and which defines the output HDR format. The disclosure further relates to an encoding/decoding method/device, a computer program product, a processor readable medium, a non-transitory storage medium and a signal.

    摘要： The present disclosure generally relates to a method and device for decoding an HDR picture from a bitstream representing a LDR picture and an illumination picture. The method comprising: - obtaining a decoded version of the HDR picture by multiplying the sample values of a decoded version of the LDR picture by the sample values of the decoded version of the illumination picture; and - obtaining a color value expressed in an output color space for each sample value of the decoded version of the HDR picture, the method is characterized in that it further comprises: - obtaining a color value expressed in the output color space for each sample value of a decoded version of the LDR picture just before multiplying said color values by the sample values of the decoded version of the illumination picture.

    摘要： An aspect of present principles is directed to methods, apparatus, systems and computer readable media for image processing. The image processing may include receiving a standard dynamic range (SDR) image or a receiver for receiving a standard dynamic range (SDR) image. It may further include determining an over-exposed region of the SDR image and determining a corrected luminance value for at least a pixel of the over-exposed region, or a processor configured to determine an over-exposed region of the SDR image and a corrected luminance value for at least a pixel of the over-exposed region. The corrected luminance value is determined based on at least one of a shape of the over-exposed region, luminance information of pixels surrounding the over-exposed region, and edge information of the pixels surrounding the over-exposed region. The over-exposed region may be an irregularly shaped region.

    摘要： A user terminal device,a server device,a system and a method for assessing quality of media data are described. The user terminal device is used for extracting artefact features from the media data and for communicating the features to the server device which is then used for determining a quality score using the artefacts and an artefact/quality score database accessible by the server device. The score, transmitted to the user terminal device, is presented to a user from which a subjective quality score and a request for re-determination are received which the user terminal device communicates to the server device. This in turn is used for re-determining the quality score and for transmitting back the re-determined quality score wherein the quality score is re-determined using the received artefacts, the received subjective quality score and the artefact/quality score database.

    摘要： Various implementations are described. Several implementations relate to one or more encoding modes that use depth information to determine a corresponding reference block. According to a general aspect, a portion of a first-view image from a first view in a multiple-view system is encoded. The portion is all or part of the first-view image. It is determined that a portion of a second-view image from a second view in the multiple-view system corresponds to the portion of the first-view image. The determination is based on a second-view depth value providing depth information for the portion of the second-view image. The portion of the second-view image is encoded using information from the encoding of the portion of the first-view image.
