Abstract: Video processing methods and apparatuses for candidate set determination for binary-tree splitting blocks comprise receiving input data of a current block partitioned from a parent block by binary-tree splitting, determining a candidate set for the current block by prohibiting a spatial candidate derived from a neighboring block partitioned from the same parent block or determining the candidate set for the current block by conducting a pruning process if the neighboring block is coded in Inter prediction, and encoding or decoding the current block based on the candidate set by selecting one final candidate from the candidate set. The pruning process comprises scanning the candidate set to determine if any candidate equals to the spatial candidate derived from the neighboring block, and removing the candidate equals to the spatial candidate from the candidate set.

Abstract: A medium of interest is interrogated according to ultrasound elastography imaging. A preliminary elasticity-spatial-map is formed. This map is calibrated against a reference elasticity-spatial-map that comprises an array (232) of different (240) elasticity values. The reference map is formed to be reflective of ultrasonic shear wave imaging of a reference medium. The reference medium is not, nor located at, the medium of interest, and may be homogeneous. Shear waves that are propagating in a medium are tracked by interrogating the medium. From tracking locations on opposite sides of an ablated-tissue border, propagation delay of a shear wave in the medium and of another shear wave are measured. The two shear waves result from respectively different pushes (128) that are separately issued. A processor decides, based on a function of the two delays, that the border crosses between the two locations.
