Offset Texture Layers for Encoding and Signaling Reflection and Refraction for Immersive Video and Related Methods for Multi-Layer Volumetric Video
An apparatus includes at least one processor; and at least one non-transitory memory including computer program code; wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: provide patch metadata to signal view-dependent transformations of a texture layer of volumetric data; provide the patch metadata to comprise at least one of: a depth offset of the texture layer with respect to a geometry surface, or texture transformation parameters; and wherein the patch metadata enables a renderer to offset texture coordinates of the texture layer based on a viewing position.

TEMPORAL DE-NOISING FOR VIDEO
A method, computer program, and computer system is provided for video coding. Video data including one or more frames is received. A static background is estimated for each of the one or more frames based on a temporal average of the one or more frames. Pixels from among the one or more frames are identified as corresponding to the static background. Noise is removed in the static background based on the identified pixels.
RESOURCE-EFFICIENT VIDEO CODING AND MOTION ESTIMATION
In one embodiment, a compute device includes interface circuitry and processing circuitry. The processing circuitry receives, via the interface circuitry, a current frame of a video stream to be encoded. The processing circuitry then determines whether a scene change occurs at the current frame. If a scene change occurs at the current frame, the processing circuitry detects the scene in the current frame by performing pixel segmentation on the current frame. If a scene change does not occur at the current frame, the processing circuitry detects the scene in the current frame by performing motion estimation on the current frame relative to a previous frame in which the scene was detected. Based on the scene detected in the current frame, the processing circuitry then generates one or more encoding parameters and provides those parameters to a video encoder to encode the current frame.
METHODS AND APPARATUS FOR COMPRESSION FEEDBACK FOR OPTIMAL BANDWIDTH
The present disclosure relates to methods and apparatus for display processing. The apparatus can calculate a bandwidth compression ratio (CR) for each of a plurality of tile rows in one or more layers in a frame, each of the one or more layers being associated with one or more regions in the frame. The apparatus can also determine a bandwidth CR for each of the one or more regions associated with each of the one or more layers based on the calculated bandwidth CR for the plurality of tile rows in the one or more layers. Additionally, the apparatus can determine a total bandwidth for the frame based on the determined bandwidth CR for each of the one or more regions associated with the one or more layers. The apparatus can also calculate a total bandwidth for each of the one or more regions.
IMAGE PROCESSING APPARATUS, VEHICLE HAVING THE SAME AND CONTROL METHOD THEREOF
A vehicle is provided and includes an image acquisition device and an image processing apparatus that receives an original frame for an image obtained by the image acquisition device at a set time interval in the parking state and obtains a key frame having the same pixel with each other by comparing a plurality of original frames received at the set time interval. The image processing apparatus obtains a plurality of delta frames having pixels different from the reference original frame from remaining original frames by comparing each of the reference original frame and the remaining original frames among the plurality of frames and compresses the key frame and the plurality of delta frames, respectively. A storage device stores the key frame and a plurality of delta frames compressed by the image processing apparatus.
Video coding using constructed reference frames
Video coding using a constructed reference frame may include generating, by a processor in response to instructions stored on a non-transitory computer readable medium, an encoded video and outputting an output bitstream. Generating the encoded video includes receiving an input video stream, generating a constructed reference frame, generating an encoded constructed reference frame by encoding the constructed reference frame, including the encoded constructed reference frame in an output bitstream such that the constructed reference frame is a non-showable frame, generating an encoded frame by encoding a current frame from the input video stream using the constructed reference frame as a reference frame, and including the encoded frame in the output bitstream.

DECOMPOSITION OF RESIDUAL DATA DURING SIGNAL ENCODING, DECODING AND RECONSTRUCTION IN A TIERED HIERARCHY
Computer processor hardware receives a first set of adjustment values. The first set of adjustment values specify adjustments to be made to a predicted rendition of a signal generated at a first level of quality to reconstruct a rendition of the signal at the first level of quality. The computer processor hardware processes the first set of adjustment values and derives a second set of adjustment values based on the first set of adjustment values and a rendition of the signal at a second level of quality. The second level of quality is lower than the first level of quality.
