Involving Sub-band Coding (epo) Patents (Class 375/E7.029)

  • Patent number: 12262042
    Abstract: According to an embodiment, an encoder is configured to ensure that for each long-term picture of a RPS of a picture i the value of a flag referred to as delta_poc_msb_present_flag[i] is equal to 1 when there are at least two reference pictures in a decoded picture buffer with lsb's of the POC referred to as pic_order_cnt_lsb equal to the lsb's of the respective long-term picture i denoted POC lsbLt[i]. When the delta_poc_msb_present_flag is equal to 1, the long-term picture is indicated by the full POC.

  • Patent number: 12262065
    Abstract: A portion Y of a degraded frame is restored using a projection operation that uses a first projection parameter ?, a second projection parameter ?, and at least two guide portions. Restoring the portion Y of the degraded frame includes generating, using first restoration parameters, a first guide portion Y1 for the portion Y; generating, using second restoration parameters, a second guide portion Y2 for the portion Y; and generating a reconstructed portion YR, wherein the projection operation is based on ?(Y1?Y)+?(Y2?Y).

  • Patent number: 11924476
    Abstract: A device for restoring a degraded frame resulting from reconstruction of a source frame includes a processor that is configured to receive a compressed bitstream. The compressed bitstream includes a first projection parameter ? a second projection parameter ?, first restoration parameters comprising a first radius value, and second restoration parameters comprising a second radius value. The processor is further configured to restore at least a portion of the degraded frame using a projection operation that uses the first projection parameter ?, the second projection parameter ?, and at least two guide tiles.

  • Patent number: 10510165
    Abstract: Techniques for compressing images based on context are provided. A first image and a second image may be identified for display on a client device. One or more contexts of the first image may be identified. One or more contexts of the second image may be identified. A first image quality for the first image may be determined based on the one or more contexts of the first image. A second image quality for the second image may be determined based on the one or more contexts of the second image. The first image may be compressed at the first image quality and the second image at the second image quality. The compressed first image and the compressed second image may be transmitted to the client device.

  • Patent number: 10419755
    Abstract: An apparatus for encoding or decoding video data reconstructs one or more blocks of a current picture of the video data. The one or more blocks of the current picture comprise reconstructed samples of the current picture. In addition, after reconstructing the one or more blocks of the current picture, the apparatus applies a particular function of a plurality of filters to a current block of the current picture. The current block comprising the reconstructed samples of the current picture.
