Rotated Image Matching And Correction Method Based On Improved Circular Projection

摘要

The key of rotated image matching is to determine the rotation invariant features. Accordingly, the circular projection algorithm is proposed. This paper presents an improved algorithm based on circular projection. Through improving the projection algorithm of radius and increasing the projection algorithm of rotation angle, this algorithm has the ability to match and rotation correction. Meanwhile, the algorithm for arbitrary rotation angle is effective, it is robust to the rotation and the noise, and it has high efficiency.
