基于边缘扩展相位相关的图像拼接算法

针对图像拼接算法中计算量大的问题，提出了一种基于边缘扩展相位相关的图像拼接算法。该算法采用迭代阈值分割法对图像进行边缘检测,并对检测出的边缘进行扩展相位相关计算，得出图像间的平移、旋转和尺度变化。利用这些参数拼接图像，用渐进渐出的方法实现拼接图像的融合。实验证明，该算法能够简化计算，并有效地实现图像的拼接。

Image Mosaic Algorithm Based on Extended Phase Correlation of Edge

To deal with the large amount of calculation of image mosaic algorithm, An image mosaic algorithm based on extended phase correlation of edge is presented. The iterative threshold segmentation approach is introduced to detect image edge. Then the image translation, rotation and scale changes are calculated by the extended phase correlation method. These parameters are utilized to stitch images. Image fusion can be achieved by fade-in-fade-out method. It is proved by experiments that this algorithm is simple to calculate, and can effectively achieve the image mosaic.
