Abstract:

The speed-up robust features (SURF) algorithm is a scale-invariant, rotation-invariant and robust

registration algorithm. However, since the color features of the image can be lost, its registration effect

of color images is poor. We therefore propose a SURF registration algorithm based on fusion features.

Firstly, we utilize the color invariant and the double local binary pattern (DLBP) texture features of the

color image to construct the grayscale of fusion features. Meanwhile, we propose an adaptive method to adjust

the weights of fusion features based on the color histogram of the color image. Then, the SURF algorithm is

used to extract and match the feature points on the grayscale of fusion features. Finally, the improved

random sample consensus (RANSAC) algorithm is used to remove the mismatch points. Experimental results show

that the proposed algorithm can effectively increase the feature points and speed up the registration rate

for color images.
