SIFT and SIFT-based algorithms are widely used in a variety of image recognition problems. However
they present the folloring two problems. The first is their expensive computational cost, especially in deciding
orientations. The second is that their peformance seriously degrades against affine transformation of target images.
A hardware-friendly algorithm employing the log polar coordinate transformation has been proposed in this paper.
Although it increases the calculation cost to transform coordinates of a local image from rectangular to log polar
ones, it can reduce calculation cost to decide orientations and discribe feature vector. Furthermore, the proposed
algorithm has enabled us to build an affine-transformation-invariant recognition system at low computational cost.
We observed many keypoints matched successfully between two images one of which is expanded, rotated and affine
transformed. |
