幀過濾 的英文怎麼說
中文拼音 [zhèngguòlǜ]
幀過濾
英文
frame filtering-

首先將視頻分解成許多連續的靜態圖像幀，經過背景去除，把感興趣的人體區域提取出來，通過二值化，中值濾波等預處理方法得到只有人體的一個單連通區域，然後用sobel運算元檢測出boundingbox最寬幀中人體下半身的輪廓，根據運動規律及特徵找到後腿踝關節點，結合從boundingbox最窄幀中所獲取的腿長依次得到後腿膝關節，跨部關節，前腿踝關節，前腿膝關節四點，從而構建出腿部骨架模型。 2 ）實現了人體步行腿部骨架的跟蹤演算法。在完成對腿部骨架模型的自動初始化之後，本文對跨關節、膝關節及踝關節分別採用運動建模、圓周相交定點演算法、運動預測及預測點周圍搜索rgb相似矩形塊三種方法確定每一幀中其實際坐標，從而重構出腿部骨架的運動過程。The proposed method combines the detection probability and temporal tracking information at each time step, therefore outperforms current frame based detection and traditional tracking methods
通過在每一時刻將人臉檢測信息融入粒子濾波器的時序信息積累和傳播機制中，演算法取得了優于逐幀檢測和傳統跟蹤演算法的性能。The transmitter does the work of a burst transmission, its encoding and framing are all implemented in the link control part, the base - band process part does the spreading, fir filtering and up frequency conversion
