Image Registration Using Edge-Based Methods
Jia Zhong, Atr State · Computer Engineering and Science · 2001
In this paper,an improved edge based method for image registration is proposed by using the accelerated wavelet transform to extract feature points as the basis for registration.All the edge directions of the feature points are estimated based on a line fitting model.The concept of angle histogram is defined to decide the rotation angle.During real matching,we check each candidate pair in advance to see if it can possibly become a real matching pair,then we use linear weights to extract correct matching pairs.
