  • Spatiotemporal registration of image streams
    Patent number: 10469725
    Abstract: There is disclosed a method for spatiotemporal registration between a first image stream and a second image stream. A first registration frame set derived from the first image stream and a second registration frame set derived from the second image stream are defined. A spatial correlation analysis is conducted based on the first registration frame set and the second registration frame set to determine a spatial registration offset. The first registration frame set and the second registration frame set are spatially registered based on the spatial registration offset. A temporal correlation analysis is conducted based on the first registration frame set and the second registration frame set after spatial registration to determine a temporal registration offset. The first image stream and the second image stream are spatially and temporally registered based on the spatial registration offset and the temporal registration offset.
