查询词典 image detector

It uses a cascade-structured face detector trained with AdaBoost to detect face.Integrated with a linear face tracker,searching region and rescaling levels of the detector are reduced,and thus detection speed is accelerated.

Maximum likelihood detector is the optimal detector and has the best performance. The challenge of MLD is the high computational complexity. K-Best decoding algorithm has been proposed to reduce the computational complexity. K-Best decoder algorithm computes Partial Euclidean Distance and only keeps the best K nodes that have the smallest accumulated PEDs. After completing breadth-first tree search, we will have K leaves with the smallest PEDs.

最大相似度侦测法是公认最佳化的演算法，有著最好的侦测效能，但运算复杂度将会随著调变群集和传送天线数目大小而呈指数型增加。K-Best球型解码演算法因而被提出来，得到近似最大相似度侦测法的结果，解决最大相似度侦测法运算复杂度过高的问题。K-Best球型解码演算法在计算完部份欧几里德距离后，需要取最小K个值做为候选点，再往下层去找候选点。
