This paper provides an algorithm for partitioning grayscale images into disjoint regions of coherent
brightness and texture. Natural images contain both textured and untextured regions, so the cues of contour and
texture differences are exploited

ASM是由Cootes和泰勒推出的多分辨率方法的一个例子。
基本思想:
在ASM模型训练,训练从手工绘制的图像轮廓。发现的ASM模型在训练使用主成分分析(PCA),使该模型自动识别数据的主要变化是,如果可能的轮廓/好的对象的轮廓。还包含了ASM模型的协方差矩阵描述行垂直纹理口岸时,在正确的位置。
