At first , this paper introduces the development history and the research status of the problem of tracking maneuvering targets , mostly introduces the interacting multiple model ( imm ) algorithm , its refinement algorithms and some maneuvering models 本文首先回顧了目標跟蹤問題的發(fā)展歷史,并介紹了該課題的研究現狀:主要介紹了交互多模型( imm )算法及其改進算法和各種機動運動模型的研究現狀。
The method reduces the data to search via decomposing the image to several effectual subimages by the wavelet , then reduces the searching space through multi - resolution analysis , and refine the solution using an iterative refinement algorithm finally 該方法利用小波變換將圖像分成若干層次,通過引入有效子圖的概念來降低待搜索的數據量,應用小波理論的多分辨分析思想來縮小搜索空間,最后通過迭代求精算法實現了圖像的快速、高精度配準。
