Abstract: A target object detection method, including: obtaining images collected by more than one camera installed on a target vehicle; determining a high-dimensional parameter feature in a high-dimensional space corresponding to parameter information of each camera; and fusing features of the images via a target object detection model according to the high-dimensional parameter features, and determining position information of a target object based on the fused features, an order of the cameras corresponding to the images being the same as an order of the cameras corresponding to the high-dimensional parameter features.

Abstract: A method and an apparatus for vehicle positioning. The method includes: acquiring a distance transformation image of a road marking object in a road image based on the road image of an environment where a vehicle is located at a current time point; acquiring a vector subgraph of the road marking object from a global vector map; and determining a target positioning posture of the vehicle based on the distance transformation image and the vector subgraph.

Abstract: A vehicle localization method and device, an electronic device and a storage medium. The vehicle localization method includes: acquiring an image of a scene where a vehicle is located, the image comprising a semantic element; determining an element category corresponding to the semantic element; matching the semantic element with a map element to acquire a matching result by a matching method corresponding to the element category; and determining localization information of the vehicle according to the matching result.

Abstract: An image chat application generates comments to images based on features of the images. In one example, the image chat application searches through a repository of stored image-comment pairs to identify a stored image that is similar to the image, and generates a comment to the image based on an identified stored image-comment pair. In another example, the image chat application may identify and tag particular objects that dominate an image, and may generate a comment to the image based on characteristics of those particular objects. In this second example, the image chat application further generates a comment to the image based on comments previously associated with the identified tag.

Abstract: Techniques and constructs to facilitate automatic tagging can provide improvements in image storage and searching. The constructs may enable training a deep network using tagged source images and target images. The constructs may also train a top layer of the deep network using a personal photo ontology. The constructs also may select one or more concepts from the ontology for tagging personal digital images.

Abstract: A computing device configured to determine that one or more regions of an image are associated with a tag of the image is described herein. The computing device is further configured to determine one or more attribute tags describing at least one of the content or context of the one or more regions. Upon determining the attribute tags, the computing device associates the attribute tags with the tag to enable image searching based on the tag and attribute tags.

Abstract: Methods and systems for active image tagging are usable to build large datasets of tagged images by combining manual tagging by a user and automatic tagging by a computing device based on the manual tagging. Such tags may be used to effectively sort, organize, link, and search for images within large datasets of images. Additionally, the active image tagging may be configured to utilize a tagging game where multiple users manually tag images by playing a game on a computing device.
