摘要： A method, apparatus and computer program product are provided for visually searching feature sets that are organized in a grid-like manner. As such, a feature set associated with a location-based grid area may be received. The location-based grid area may also be associated with the location of a device. After receiving query image features, a visual search may be performed by comparing the query image features with the feature set. The search results are then returned. By conducting the visual search within a feature set that is selected based upon the location of the device, the efficiency of the search can be enhanced and the search may potentially be performed by the device, such as a mobile device, itself.

摘要： For each prediction unit (PU) belonging to a coding unit (CU), a video coder generates a candidate list. The video coder generates the candidate list such that each candidate in the candidate list that is generated based on motion information of at least one other PU is generated without using motion information of any of the PUs belonging to the CU. After generating the candidate list for a PU, the video coder generates a predictive video block for the PU based on one or more reference blocks indicated by motion information of the PU. The motion information of the PU is determinable based on motion information indicated by a selected candidate in the candidate list for the PU.

摘要： In one example, an apparatus includes a video encoder configured to partition a block of video data into a first geometric partition and a second geometric partition using a geometric motion partition line, wherein the block comprises N×N pixels, divide the block of video data into four equally-sized, non-overlapping (N/2)×(N/2) sub-blocks, and encode at least one of the sub-blocks through which the geometric motion partition line passes using a transform size smaller than (N/2)×(N/2). The video encoder may determine transform sizes for the sub-blocks based on whether the geometric motion partition line passes through the sub-blocks. In one example, a video decoder may inverse transform the sub-blocks, and may determine transform sizes for the sub-blocks based on whether the geometric motion partition line passes through the sub-blocks.
