基于灰度相关特征点的图像拼接算法

提出了一种基于特征点的图像拼接算法,首先利用Harris角点检测提取两幅图像中的特征点,用特征点邻域灰度相关性将特征点进行匹配,并在此基础上根据变换参数向量的欧式距离对误匹配进行剔除,进而实现图像拼接.实验表明,这种算法能有效的排除误匹配的干扰,降低误匹配率,拼接效果良好.

Image Mosaic Method Based on Gray Scale Feature Points

An image mosaic method based on feature points matching was presented.The feature points from two images were extracted by Harris corner detector,then the corresponding feature point pairs were got by the cross-correlation of the gray scale around the feature points,and the mismatched pairs were eliminated based on the Eulerian distance of the transformation parameter vector.At last the images could be stitched by the corresponding pairs of features.The experiments showed that this algorithm can avoid the i...
