    • 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.
    • 公开了用于第一图像流和第二图像流之间的时空配准的方法。 定义从第一图像流导出的第一注册框集合和从第二图像流导出的第二注册框集合。 基于第一登记帧集合和第二登记帧集合进行空间相关性分析以确定空间登记偏移量。 基于空间配准偏移来空间配准第一配准帧集合和第二配准帧集合。 基于空间配准后的第一配准帧集合和第二配准帧集合进行时间相关性分析,以确定时间配准偏移量。 基于空间配准偏移量和时间配准偏移量,空间和时间配准第一图像流和第二图像流。
