Computer-vision-assisted location accuracy augmentation
Abstract:
In one embodiment, an uploaded multimedia object comprising a photo image or video is subjected to computer vision algorithms to detect and isolate objects within the multimedia object, and the isolated object is searched against a photographic location database containing images of a plurality of locations. Upon detecting a matching object, the location information associated with the photograph in the database containing the matching object may be leveraged to improve the location determination of the client device uploading the multimedia object.
Abstract(Chinese):

在一个实施例中，包括照片图像或视频的已上传的多媒体对象经历计算机视觉算法以检测和隔离多媒体对象内的对象，并且针对包含多个位置的图像的摄影位置数据库搜索被隔离对象。 在检测到匹配对象时，可以利用与包含匹配对象的数据库中的照片相关联的位置信息来改善上载多媒体对象的客户端设备的位置确定。
