Translation, rotation and scaling changes in image registration based affine transformation model
Zeng Wen · Infrared and Laser Engineering · 2001
In this paper, translation, rotation and scale properties of 2\|D affine transformation are discussed. Visual and IR image registration require a feature\|based apporach. Establishing affine transformation and extracting edge points as feature, this method calculates the cross\|correlation between edges and searches out the relation of corresponding edge points. The maximum correlation principle is involved to adaptively determine the optimal registration parameters k、θ、Δx and Δy . Experimental results using real visual/IR sensor image are presented. It is shown that this model is effective in image registration.
