This thesis is to present and analyze one class of regularized multi - grid algorithms ( rmga ) for solving operator equations of the first kind. the rmga employs tikhonov ' s regularization to solve the corase grids equations with a new choicing parameter ' s posteriori - method for improving the numerical stability, and adopts a new smoothing strategy to correct the solutions on the fine grids for preserving the high efficiency of mgm. meanwhile, some key technical problems in the process of implementation of rmga are disscussed
本文將提出一類適合第一類運算元方程的正則化的多重網格演算法，它結合一種新的正則參數選取準則，應用tikhonov正則化來求解粗網格方程保證了求解的穩定性；而在將解向細網格延拓時使用了一種新的光順處理策略。A two - stages orientation of object has been developed, which is general orientation firstly, then from this orientation point expanding to search the edge of the objective region. it can ge the center of the image after extracting the image edge. this method can greatly reduce the computer quantity of the feature extract and stereo matching and then improve the speed of recognition
提出並實現了分階段定位策略，即先宏觀粗定位，然後從從該點出發向外擴張尋求目標區域的邊緣輪廓，提取到圖象的邊緣后，再獲取圖象形心，該方法大大減小了特徵提取和立體匹配的計算量，提高了識別速度。
