Research Trend Analysis for EO-IR Image Registration

EO sensor and IR sensor have complementary characteristics. Therefore, registering two different sensors (especially EO-IR) to obtain accurate multi-images is an important part of many image-based applications such as surveillance and automatic target recognition (ATR). However, since images obtained from different sensors have significant differences in image content, an additional method is required to the existing registration technique. In general, there are classical techniques and deep learning techniques for multiple image registration techniques, and this paper introduces the techniques and development trends for them.
