    Abstract: Embodiments of the present invention provide an optical add/drop multiplexer, including a plurality of tunable optical add/drop multiplexers T-OADMs. Each T-OADM includes a second wavelength control unit and two grating-assisted filters GAFs. The second wavelength control unit is connected to a second GAF. A drop port of a first GAF is connected to an input port of the second GAF. An add port of the first GAF is connected to an output port of the second GAF. An input port of the first GAF receives light waves of a plurality of wavelengths. The first GAF transmits a first light wave to the input port of the second GAF through the drop port of the first GAF. The second wavelength control unit changes a dropped spectrum of the second GAF based on first amplitude of wavelength shift, to obtain a first light wave response.

    Abstract: Embodiments of this application disclose a method and an apparatus for determining an image loss value, a storage medium, and a program product, and belong to the field of image compression technologies. In this method, loss values of different areas in an image are determined based on a partition indication map of the image, and then a total loss value is determined based on the loss values of the different areas. The partition indication map may be used to distinguish between a heavily-structured area and a lightly-structured area in the image, that is, the partition indication map may be used to distinguish between an edge structure and a texture. When the total loss value is used to assess image reconstruction quality, the image reconstruction quality can be assessed more comprehensively, and assessment of reconstruction quality of the edge structure and the texture can be maximally prevented from mutual impact.

    Abstract: Embodiments of this application disclose encoding and decoding methods, apparatuses, and devices, a storage medium, and a computer program, which relate to the field of encoding and decoding technologies. In embodiments of this application, in a decoding process, a plurality of feature points are divided into a plurality of groups based on a specified numerical value, and probability distributions of feature points in a same group are determined in parallel to improve decoding efficiency. Correspondingly, in an encoding process, the plurality of feature points are also grouped in a same grouping manner, and first image features of each group of feature points in the plurality of groups are sequentially encoded into a bit stream. To be concise, this solution can break through an efficiency bottleneck caused by serial computing when decoding is performed based on a variational auto-encoder (VAE), thereby effectively improving decoding efficiency.
