Abstract: Methods and systems for media trend detection and maintenance are provided herein. A set of media items each having common media characteristics is identified. A set of pose values is determined for each respective media item of the set of media items. Each pose value is associated with a particular predefined pose for objects depicted by the set of media items. A set of distance scores is calculated. Each distance score represents a distance between the respective set of pose values determined for a media item and a respective set of pose values determined for an additional media item. A coherence score is determined for the set of media items based on the calculated set of distance scores. Responsive to a determination that the coherence score satisfies one or more coherence criteria, a determination is made that the set of media items corresponds to a media trend of a platform.

Abstract: Disclosed is a dynamic regulation method for a lane changing decision point of a CAV dedicated lane in a diverging area of an expressway, applied to the diverging area of the expressway in which the CAV dedicated lane is provided at an inner side of a road.

Abstract: The present application provides a processing method of a metal composite structure including a first metal layer and a second metal layer stacked on the first metal layer. The processing method includes the steps of defining a first through hole in the first metal layer, and drilling in the first through hole toward the second metal layer to form a traction hole in the second metal layer. Then, hot melt drilling is performed on a surface of the second metal layer away from the first metal layer toward the first through hole, thereby causing the second metal layer to crack under a traction force of the traction hole to form a second through hole, and a portion of the second metal layer to be melted and squeezed to form a bushing which adheres to at least a portion of a sidewall of the first through hole.

Abstract: Methods and apparatus for video processing are disclosed. The processing may include video encoding, video decoding, or video transcoding. One example method includes performing a conversion between a current block of a video and a bitstream of the video.
