Shape matching and feature extraction of cross based on fourier transform and specific spatial matching

In this paper, the method we constructed aims to accurately identify the cross light hub emitted by a cross laser light. However, image recognition technologies are largely limited due to varying light conditions, and this image processing method introduced in our paper ingeniously overcomes such barriers.

The feature extraction of a cross is based on the Fourier Transform (FT) and specific spatial matching (SSM). The combination of these two feature extraction technologies ensures the accuracy of image recognition in a variety of light conditions.
