基于 ASIFT 的医学图像配准算法
Medical Image Registration Algorithm Based on ASIFT
摘要
Abstract
This paper analyzes the principle of ASIFT algorithm.For medical image registration of high robustness, high accu-racy and low consumption rate, this paper proposes a medical image registration algorithm based on ASIFT .This algorithm extracts feature points from images by the ASIFT algorithm, then matches the feature points by the Euclidean distance, and achieves the medical image registration between two images at last.The algorithm effectively deals with the problems such as less feature points collected, inaccuracy matching appeared in feature points, being incapable to registration on distorted affine image, etc.,which exist in other algorithms.The experimental result verifies that the algorithm not only improves the registration accuracy and preci-sion, but also enhances the stability and reliability of the registration.关键词
