Fast Algorithm of calculating Invariant Features for Image Matching

摘要

Image matching method is an important technique in image processing. It gives reference and methodology to fully use different kinds of data. An image matching method based on invariant features of image and image data basis generating method are presented in this paper. The method is realized by following procedures: first, we establish the image data basis, then we change the newly obtained iamge to scale of the base image, and finally we use invariant features of image to correlate the base image and the newly obtained image, in this way to find the best matching point. At the same time, a fast algorithm is introduced in this paper to calculate the invariant features of image. The method is insensitive to translation, rotation and scale; also it is simle and stable.
