2022 IEEE 8th International Conference on Computer and Communications (ICCC)
Year: 2022 | Conference Paper |
In recent years, due to the wide application of multi-sensor vision systems, multi-modal image acquisition technology has continued to develop. Most of the existing multi-modal image registration methods are only suitable for two modalities, and cannot uniformly register multiple modal image data. Therefore, our method proposes a multi-modal image registration method based on adaptive multi-scale ...Show More
