    • An image of an actual pattern of discrete objects is analyzed with respect to a model representing a predefined ideal pattern of objects. Initial processing is performed on only a portion of the image associated with ones of the objects located in an original neighborhood within the image to determine information about an affine transformation of the actual pattern of the discrete objects relative to the predefined ideal pattern. Additional processing is performed on other portions of the image based on the results of the initial processing. Initial processing is performed with respect to a first part of the image by operating on only a first portion of all of the digital data that represents that first part of the image. Later additional processing is performed with respect to another part of the image by operating on only a second portion of all of the digital data that represents that other part of the image, the second portion being relatively smaller than the first portion so that the additional processing is less intensive than the initial processing.
    • 对于表示预定理想的对象图案的模型,分析离散对象的实际图案的图像。 仅对与位于图像内的原始邻域中的对象相关联的图像的一部分执行初始处理,以确定关于相对于预定理想图案的离散对象的实际图案的仿射变换的信息。 基于初始处理的结果对图像的其他部分执行附加处理。 通过仅对表示图像的第一部分的所有数字数据的第一部分进行操作,对图像的第一部分执行初始处理。 稍后通过仅对表示图像的其他部分的所有数字数据的第二部分进行操作来执行关于图像的另一部分的附加处理,第二部分相对小于第一部分,使得附加处理 比起初处理要少得多。
