中文拼音 [tuōwěitúxiàng]
拖尾圖象
英文
streak image-
On the basis of image segmentation, this thesis mainly discusses the algorithm of automatic target tracking in sequence images on the sea. firstly, in terms of the characteristics of image on the sea, such as weak contrast between target and background, borderline between sky and sea, spoondrift and so on, a method called barycenter tracking which is based on intra - frame information from the sequence images is proposed, in which the threshold method is the key algorithm
在圖象分割演算法研究的基礎上，本文重點從兩方面討論了海上序列圖象中運動目標的自動跟蹤演算法:首先，針對海上圖象的特點，即背景與目標間的弱對比度、存在海天線、魚鱗光和目標拖尾等，設計了以閾值分割為核心的基於幀內信息的形心跟蹤方法。In the dissertation, the author uses objective and subjective measurement respectively to compare among philips ' s 1st ( c ' s algorithm, philips ' s 2nd ic ' s algorithm and our own motion compensated algorithm. simulation shows our algorithm solves the problem of horizontal edge flicker in saa4991, alleviates the problem of " tear " in saa4992. the author also uses subjective measurement to compare among our edge - based motion adaptive de - interlacing algorithm, traditional intra - field interpolation algorithm and faroudja ' s dcdi algorithm. simulation shows our own edge - based algorithm can remove the sawtooth on the object ' s edge, and has basically reach the level of dcdi
論文從主觀和客觀兩個角度對比分析了自有的運動補償演算法和飛利浦一代晶元saa4991 、二代晶元saa4992中的運動補償演算法的性能：自有演算法對于圖像的水平邊有效抑制了saa4991存在的閃爍現象，減小了saa4992存在的拖尾問題；自有的邊沿演算法消除了傳統演算法在物體邊沿處存在的鋸齒，可以得到清晰平滑的邊沿，基本達到了dcdi演算法的水平。
