Title:
マッチムーブ用のハイブリッド追跡器のシステム及び方法
Document Type and Number:
Japanese Patent JP7227145
Kind Code:
B2
Abstract:
A system and method that maximizes tracking speed of an object in a sequence of images by selecting a technique for tracking the object independently for each frame in a video. The system includes an object feature detector that detects object features in a reference frame of the video and a feature comparator that determines a number of object features in each frame in the sequence of images that match the detected object features in the reference frame. Moreover, a tracking pattern selector selects the type of object tracking to track the object in the current frame based on the determined matched object features between the reference frame and the current frame of the video.
