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.
