本文提出一種採用可變形模板匹配技術進行基於內容的圖像分割演算法.通過預先計算出可變形模板沿著變形的正交曲線，並對模板曲線及正交曲線進行離散抽樣，建立一基於正交曲線的二維（ 2 - d ）可變形模板，針對圖像分割問題定義控制可變形模板進行變形的內、外部能量函數，本文採用遺傳演算法搜索能量函數最小的全局最優解.該新演算法比傳統的可變形模板匹配方法降低了搜索空間的維數，減少了演算法對模板初始位置的敏感.對實際圖像及模擬低信噪比圖像處理的結果表明，新演算法具有良好的分割精度及穩定性The thesis is focused on above associated issues. ransac algorithm is a classical method of robust model parameter estimation. a preview model parameters evaluation ransac ( peransac ) algorithm is developed, which introduces a preview model parameters evaluation in the ransac algorithm, and results in better performance since the worse contaminated samples are discarded with guaranteeing the same confidence as ransac
