针对图像特征提取与匹配的适应性和准确性的问题
本文提出将尺度不变特征变换算法应用到图像特征点提取与匹配。算法首先采用SIFT提取图象的特征点及其描述,然后采用基于置信度的匹配算法进行特征点的匹配。通过对不同光照条件、焦距、拍摄角度的图像进行特征点的提取及匹配,实验结果表明,本文算法对图像的平移、旋转和仿射变换具有很好的适应性和准确性
可以进一步应用到图像识别,图像重建等领域。
In order to improve the stability and reliability of image matching
this paper applied the scale invariant feature transform algorithm to image matching. First
uses SIFT method to get the special point and its feature. Then
matches the features with the criterion of nearest neighbor based on confidence. After experiments on different images
the results prove that the features extracted by SIFT method have excellent adaptive and accurate characteristics
which are useful for the fields of image recognition and image reconstruction.
