20220286696 | IMAGE COMPRESSION METHOD AND APPARATUS - An image compression method includes obtaining a hidden variable of an input image using a coding network of a deep learning neural network comprising at least one downsampling back projection module including performing downsampling transformation on a first feature map of the input image input to the downsampling back projection module to obtain a second feature map, obtaining a third feature map having a same resolution as a resolution of the first feature map by reconstructing the second feature map, and obtaining a fourth feature map as an optimization result of the second feature map, based on a difference value between the first feature map and the third feature map; and obtaining a bitstream file of a compressed image by performing entropy coding based on the hidden variable obtained based on the fourth feature map of a last downsampling back projection module. | 2022-09-08 |
20220286697 | APPARATUS, SYSTEM, AND METHOD FOR VIDEO ENCODING AND LOADING TAPE CARTRIDGES - The disclosed computer-implemented method may include receiving video data to be encoded, determining pixels for a first transform unit (TU) of a first prediction unit (PU) of a square shape of the video data, storing the pixels in a buffer, performing intra-prediction for a second PU by reusing the stored pixels for a second TU of the second PU, and encoding the video data based on the intra-prediction. A system may include a video encoder and/or a tape holder apparatus. The tape holder apparatus may include a cubical tape holder to hold multiple tape cartridges in a stack, wherein a tape cartridge may be inserted into a top of the cubical tape holder. The tape holder apparatus may include a handle and a horizontal slot enabling a single tape cartridge to be pushed out from a bottom of the stack. Various other methods, systems, and apparatuses are also disclosed. | 2022-09-08 |

20220286700 | IMAGE OR VIDEO CODING BASED ON PALETTE ESCAPE CODING - According to the disclosure of the present document, information used in a palette coding mode may be effectively signaled. For example, information relating to availability of a palette mode may be signaled, and information relating to a quantized escape value may be signaled on the basis of the information relating to the availability of the palette mode. In addition, as a quantization parameter for the quantized escape value, minimum quantization parameter information relating to a transform skip mode may be signaled. Accordingly, information required for palette mode coding can be efficiently signaled, and escape coding efficiency in a palette mode can be improved. | 2022-09-08 |
