PAN Zi-yang, ZHANG Hai-yan. Fast image registration algorithm based on improved feature point detection[J]. 2018, (4): 148-150+160. DOI: 10.13873/J.1000-9787(2018)04-0148-03.
In view of slow efficiency and false detection on feature point of traditional feature point registration algorithm
propose an algorithm for image registration which is based on feature point detection.Detection method of feature points is improved
use gray relationship between pixels and surrounding pixels to filter non-feature points.Next
sets up a set of feature points
after detect remained points accurately.Iterative closest point(ICP) algorithm is used to match set of feature points. The experimental results show that the proposed algorithm significantly improves detecting accuracy and detecting time
