    摘要： A method for viewing pathology images in a web browser is provided. The method includes obtaining a pathology image in a first format, converting the pathology image into a pyramid representation file comprising images grouped into a plurality of levels, wherein the images in the different plurality of levels correspond to portions of the pathology image at a same or different degrees of resolution, and wherein the images are in the first format, storing the pyramid representation file in the first memory, receiving a request from a user to view the pathology image at a specified resolution, loading one or more images from at least one of the plurality of levels corresponding to the specified resolution, wherein the one or more images are in the first format and wherein the one or more images are loaded into a web browser coupled with the first memory, converting the images into a second format such that the images' degrees of resolution are maintained, and storing the images in the second format in a second memory.

    摘要： There is provided methods and apparatus of encoding/decoding point cloud geometry data represented by ordered coarse points occupying some discrete positions of a set of discrete positions of a two-dimensional space. The encoding method comprises obtaining (105) at least one binary data (f j ) representative of an order index difference representative of a difference between order indices of two consecutive occupied coarse points and encoding each of said at least one binary data (f j ) by:
    - obtaining (120) coordinates ( s j , λ j ) of a current coarse point ( P j ) within the two-dimensional space;
    - obtaining (130) a sensing number ( N sens ( s j , λ j )) from the current coarse point ( P j ), said sensing number ( N sens ( s j , λ j )) being representative of an average number of consecutive sensing needed by a sensor ( λ j ) associated with the current coarse point ( P j ) to sense another coarse point; and
    - entropy encoding (150), into the bitstream, the binary data (f j ) based on the sensing number ( N sens ( s j , λ j )) .

    摘要： Methods and systems for encoder parameter setting optimization. A media item to be provided to one or more users of a platform is identified. The media item is associated with a media class. An indication of the identified media item is provided as input to a first machine learning model. The first machine learning model is trained to predict, for a given media item, a set of encoder parameter settings that satisfy a performance criterion in view of a respective media class associated with the given media item. One or more outputs of the first machine learning model are obtained. The one or more obtained outputs include encoder data identifying one or more sets of encoder parameter settings and, for each of the sets of encoder parameter settings, an indication of a level of confidence that a respective set of encoder parameter settings satisfies the performance criterion in view of the media class associated with the identified media item. The identified media item is encoded using the respective set of encoding parameter settings associated with the level of confidence that satisfies a confidence criterion.

    摘要： A point-cloud decoding device 200 according to the present invention includes: a geometry information decoding unit 2010 configured to decode a flag that controls whether to apply "Implicit QtBt" or not; and an attribute-information decoding unit 2060 configured to decode a flag that controls whether to apply "scalable lifting" or not; wherein, a restriction is set not to apply the "scalable lifting" when the "Implicit QtBt" is applied.
