A novel method of content - based image segmentation using deformable template matching is proposed . a two - dimensional ( 2 - d ) deformable template based on orthogonal curves is built by pre - computing extensions of the deformable template along orthogonal curves and sampling the curves uniformly . then the definitions of internal and external energy functions are given according to the image segmentation problem , and genetic algorithm is used to obtain globally optimal solutions . the proposed method uses a lower - dimensional search space than conventional methods and reduces the sensitivity of the algorithm to initial placement of the template . experiments on real - world images and in simulations at low signal - to - noise ratio show the robustness and good performance of the method 本文提出一種采用可變形模板匹配技術(shù)進(jìn)行基于內(nèi)容的圖像分割算法.通過預(yù)先計(jì)算出可變形模板沿著變形的正交曲線,并對(duì)模板曲線及正交曲線進(jìn)行離散抽樣,建立一基于正交曲線的二維( 2 - d )可變形模板,針對(duì)圖像分割問題定義控制可變形模板進(jìn)行變形的內(nèi)、外部能量函數(shù),本文采用遺傳算法搜索能量函數(shù)最小的全局最優(yōu)解.該新算法比傳統(tǒng)的可變形模板匹配方法降低了搜索空間的維數(shù),減少了算法對(duì)模板初始位置的敏感.對(duì)實(shí)際圖像及模擬低信噪比圖像處理的結(jié)果表明,新算法具有良好的分割精度及穩(wěn)定性
