    Abstract: An encoding apparatus, decoding apparatus, and coding methods. The encoding apparatus includes a processor configured to receive a video frame including screen content, generate a block containing an index map of colors for screen content in the video frame, wherein the block includes strings of index values sharing a same escape color index value, wherein the escape color index value represents an escape color, encode each of the strings of index values in the block, and sequentially encode the escape colors after each of the strings of index values in the block has been encoded. A transmitter operably coupled to the processor is configured to transmit the strings of index values and the escape colors in a bitstream to a decoding apparatus.

    Abstract: A computing device includes a communication interface, a memory, and processing circuitry. The processing circuitry is coupled to the communication interface and to the memory and is configured to execute the operational instructions to perform various functions. The computing device is configured to process a video frame of a video segment on a per-frame basis and based on joint human-object interactive activity (HOIA) to generate a per-frame pairwise human-object interactive (HOI) feature based on a plurality of candidate HOI pairs. The computing device is also configured to process the per-frame pairwise HOI feature to identify a valid HOI pair among the plurality of candidate HOI pairs and to track the valid HOI pair through subsequent frames of the video segment to generate a contextual spatial-temporal feature for the valid HOI pair to be used in activity detection.

    Abstract: In an embodiment, the disclosure includes an object detecting device. The object detecting device is configured to execute the instructions to: obtain a first picture comprising a first object at a first time instant; determine a first feature pattern of the first object based on the first picture; generate a first feature map of the first object based on the first feature pattern; generate a first feature vector of the first object based on the first feature map; and send the first feature vector to a server. In this embodiment, the first feature vector is generated based on the first feature map by the object detecting device rather than starting another process of directly generating the first feature map based on the first picture. Therefore, the speed and the computing resource cost of generating the feature vector may be better.

    Abstract: An apparatus is configured to perform a method for screen content encoding. The method includes deriving a palette table and a color index map based on a coding unit (CU). The method also includes encoding the palette table and encoding the color index map. The method further includes combining the encoded palette table and the encoded color index map for transmission to a receiver, where the palette table and index map are decoded to reconstruct a pixel block.
