TECHNIQUES TO PERFORM VIDEO STABILIZATION AND DETECT VIDEO SHOT BOUNDARIES BASED ON COMMON PROCESSING ELEMENTS

机译:基于通用处理元素的视频稳定化和检测视频拍摄边界的技术

摘要

An apparatus, a system and a method for performing video stabilization and detecting video shot boundaries are disclosed. The method includes: receiving a current frame of a video; down-scaling the current frame; storing the down-scaled current frame into a portion of a buffer; determining the sum of the absolute differences between the blocks in a down-scaled reference frame and a target block in the down-scaled current frame; determining the inter-frame dominant motion parameters of the down-scaled current frame; and performing at least one of the video stabilization and the shot boundary detection based in part on at least one of the motion parameters and the sum of the absolute differences.
