| Summary: | Systems and methods of iterative multi-directional image search are described. Embodiments use a multi-directional search pattern to determine one or more search regions within a source image. To search for a template image in multiple directions of a multi-directional search pattern, a search region of an embodiment provides a search region within a source image. The location of the search regionwithin the source image may be iteratively updated, such as based on a motion vector derived from the search, until a template image matching location is identified within the source image. Embodiments convert search regions within the template image and the source image into 1D representations corresponding to each direction of the multi-directional image search. Embodiments accommodate rotational and zoom changes in a subject of a template image, such as a target of interest, within a source image.
描述了迭代多方向图像搜索的系统和方法。实施例使用多方向搜索模式来确定源图像内的一个或多个搜索区域。为在多方向搜索模式的多个方向上搜寻模板图像，实施例的搜索区域提供源图像内的搜索区域。可以迭代地更新源图像内搜索区域的位置，例如基于从搜索导 |
