    • A method of building a statistical shape model by automatically establishing correspondence between a set of two dimensional shapes or three dimensional shapes, the method comprising: a) determining a parameterisation of each shape, building a statistical shape model using the parameterisation, using an objective function to provide an output which indicates the quality of the statistical shape model; performing step a) repeatedly for different parameterisations and comparing the quality of the resulting statistical shape models using output of the objective function to determine which parameterisation provides the statistical shape model having the best quality, wherein the output of the objective function is a measure of the quantity of information required to code the set of shapes using the statistical shape model.
    • 一种通过自动建立一组二维形状或三维形状之间的对应关系来建立统计形状模型的方法,所述方法包括:a)确定每个形状的参数化,使用参数化建立统计形状模型,使用目标函数 提供指示统计形状模型的质量的输出; 对于不同的参数重复执行步骤a),并使用目标函数的输出来比较所得到的统计形状模型的质量,以确定哪个参数化提供具有最佳质量的统计形状模型,其中目标函数的输出是 使用统计形状模型编码形状集所需的信息量。
