Coefficients in the affine transformation have been estimated using optical flow method [16], least square method [34], and numerical optimization method [35], However, Pan [16] proposed direct a cost function which minimizes the sum of squared differences between pre- and post-deformation sub-images, and this method has higher time cost.
For the affine transformation case, the optimal CPP set contains 22 CPPs with RMS = 19.
Table 1 shows the segmentation performance (median of AED distances in pixels) as a function of the number of PCA components of the affine transformation used in the statistical connection model.
Two curve segments are equivalents if they can be obtained one from the other using an affine transformation.
In general, that index is an affine transformation which does not yield a ratio scale.
An affine transformation behaves somewhat like a drafting machine that takes in a drawing (or the coordinates of all the points making up the lines in a drawing), then shrinks, enlarges, shifts or skews the picture and, finally, spews out a distorted version of the original.
This would amount to applying the unique affine transformation of the whole plane that moves the old three points to the new three points (and all our features accordingly).
