摘要: Sensor data is encoded for transmission to a receiver by applying an object detection technique to the sensor data to detect an object in the sensor data and, to determine one or more attributes of the object, encoding the sensor data to obtain encoded sensor data. The encoding includes applying a data compression technique to the sensor data. The data compression technique is configurable by one or more compression parameters. The applying of the data compression technique to the sensor data includes selecting at least one of the compression parameters based on the attributes of the object, generating object data indicative of the attributes of the object, and sending the encoded sensor data and the object data to the receiver to enable the receiver to select one or more decompression parameters of a data decompression technique based on the one or more attributes of the object.

摘要: Disclosed are methods and apparatuses for decoding an image. A method includes receiving a bitstream obtained by encoding the image; dividing a first coding block into a plurality of second coding blocks; generating a prediction block of a second coding block based on syntax information obtained from the bitstream; and reconstructing the second coding block based on the prediction block and a residual block of the second coding block, the residual block being obtained by performing a dequantization and an inverse-transform on quantized transform coefficients from the bitstream. The first coding block has a recursive division structure. The first coding block is divided based on at least one of a quad tree division, a binary tree division or a triple tree division.

摘要: This disclosure relates to video coding and more particularly to techniques for intra prediction coding. In one example, a method of decoding video data is disclosed. The method comprises: parsing a value of a flag indicating whether an intra prediction mode used for generating a prediction for a current video block is a planar mode, wherein the value for the flag is encoded using a context value selected from a set of contexts; and determining whether the intra prediction mode used for generating the prediction for the current video block is the planar mode based on the parsed value of the flag.
