- And the basic methods for building up austenitic recrystallization model,austenitic phase transformation model,structure model and mechanical model are further described as well.
- Since it was proved that the homography between two windows of corresponding feature can be geometrically approximated by an affine transformation model.
- Finally，the registered images are obtained by translating，rotating，and/or reducing/magnifying the images to be registered through using the affine transformation model again.
- The paper focuses on transform model for spectra overlapping and three algorithms of transform matrix determination,and the character of each algorithm was presented.
- Due to the existence of the outliers, direct use of least square algorithm would lead to the inaccurate parameter estimation of the transformation model that is required in image registration.
