二階層式語意描述子視訊分析

Video Analysis for Two-Levels Semantic Descriptors

摘要


本篇論文提出「二階層式語意描述子視訊分析」的方法,目標是以視訊事後分析建立詮釋資料產生器。以移動物件為基礎,分析移動物的視訊特徵,粹取出可能出現中階語意或事件的畫面,再計算感測運動能量,以所提出之演算法找出重要的關鍵畫面,計算各關鍵畫面中移動物件之中階及低階特徵,以二階層式的方式記錄視訊語意描述子的詮釋資料。

並列摘要


This paper proposed a method of 'video analysis for two-level semantic descriptors.' The goal is to construct a metadata generator by means of off-line video analysis. Visual features of moving objects are analyzed based on detected moving objects to extract candidate frames which have possible middle-level semantics. Important key frames can then be obtained by means of the proposed algorithm revised from the prior art 'Perceived Motion Energy' method. Middle and low level metadata will be computed for the extracted objects in all key frames.
