Patent number: 11051018Abstract: Improved transforms are used to encode and decode large video and image blocks. During encoding, a prediction residual block having a large size (e.g., larger than 32×32) is generated. The pixel values of the prediction residual block are transformed to produce transform coefficients. After determining that the transform coefficients exceed a threshold cardinality representative of a maximum transform block size (e.g., 32×32), a number of the transform coefficients are discarded such that a remaining number of transform coefficients does not exceed the threshold cardinality. A transform block is then generated using the remaining number. During decoding, after determining that the transform coefficients exceed the threshold cardinality, a number of new coefficients are added to the transform coefficients such that a total number of transform coefficients exceeds the threshold cardinality. The transform coefficients are then inverse transformed into a prediction residual block having a large size.Type: GrantFiled: September 4, 2020Date of Patent: June 29, 2021Assignee: GOOGLE LLCInventors: Urvang Joshi, Debargha Mukherjee

Patent number: 10986366Abstract: In a particular implementation, a video decoder may decode an initial motion vector predictor from the bitstream for a current block, and perform motion search in a small search window to refine the initial motion vector predictor. The initial motion vector may be rounded before being refined. The motion refinement can be based on a discontinuity measure between pixels of a current block and pixels of adjacent block, and can also be based on gradients between the current block and adjacent blocks. The motion vector for the current block is then decoded based on the refined motion vector predictor, and the motion vector difference if there is any. The motion refinement can also be performed on the motion vector for the current block directly. Through motion refinement, the decoder may increase the motion resolution. A corresponding video encoder may choose whether to use motion refinement based on encoder decisions.Type: GrantFiled: June 27, 2017Date of Patent: April 20, 2021Assignee: InterDigital VC Holdings, Inc.Inventors: Philippe Bordes, Fabien Racape, Tangi Poirier, Franck Galpin
