Abstract: Aiming for a good image matching resistant to interference, this paper proposes a modified EMR method to improve image edge match. For the Edge Matching Rate (EMR) between the target image and the template, generalized area is defined and used as the calculation basis in our proposed approach. It also defines similarity of local occlusion and of local dither to measure interference degree. Not only edge points are considered but also non-edge points, occlusions and dithers. After the same image edge extraction and coarse registration, the experiments use traditional EMR and proposed EMR separately to get fine registration. The experiments show that our method achieves more stable registration and better precision.
