SIFT 特征描述符扩散距离图像匹配The SIFT(Scale Invariant Feature Transform) algorithm is now regarded as the best local feature extraction and matching algorithm. However, in the traditional SIFT algorithm, the Euclidean distance which could not change the high-dimensional feature vector into a low-...
but rather on a suitable dissimilarity measure among the objects. In this paper, we study a new way of measuring the dissimilarity between two object images using a SIFT (Scale Invariant Feature Transformation) algorithm [5], which transforms image data into scale...
Aiming at improving the performance of scale invariant feature transform (SIFT) algorithm during the registration of optical and synthetic aperture radar (SAR) images, a new SIFT algorithm is proposed. Firstly, the nonlinear diffusion scale space of optical and SAR images is constructed by using non...
In the new algorithm, Curvelet first used to denoise, then RANSAC optimized SIFT algorithm used to stitch images. Experiments show that the new algorithm is better to remove error matching points. It improved the accuracy of local invariant feature matching. New algorithm has a good anti-noise ...
换.SIFT算法首先在尺度空间进行特征检测,确定 特征点的位置和所在尺度,然后用特征点邻域梯度 的主方向作为该点的方向,以实现算子对尺度和方 向的无关性. SIFI算法主要分为以下几个部分: (1)构建尺度空间、检测极值,初步确定特征点 第1期尚明姝:基于改进SIFT特征匹配的快速图像拼接算法 ...
In this process a feature extraction algorithms such as SIFT and a Corner detection algorithm is used. SIFT provides good results when there are scale variations and rotations and when there are less rotations corner detection algorithms can perform better.M. S. Bhosale...
