Abstract: Example implementations described herein are directed to a tag using a color/pattern coding scheme for better use in industrial settings which may involve curved objects such as pipes. The tag can include one or more anchors indicative of an orientation of the tag; a calibration pattern mapping each of a plurality of colors/patterns to one or more values; and encoded information provided on the tag in one or more of the plurality of colors/patterns. The tag may be printed directly on the object to ensure longevity and readability, or attached as a sticker or printed label depending on the desired implementation.

Abstract: An image processing device includes a processor, a storage unit coupled to the processor and storing an image database, and a display unit coupled to the processor. The processor obtains arrangement information of a first object on the display unit when the processor accepts an input of the first object via the display unit. The processor obtains first co-occurrence information using the first object and the arrangement information of the first object. The first co-occurrence information indicates a correlation relationship with the first object based on the image database. The processor outputs a candidate for a second object based on the first co-occurrence information to the display unit.

Abstract: In example implementations described herein, person images obtained by object detection and tracking are stored in an image database. Then the system automatically samples a person image as a query of image search for past images. Filtering is performed on the search results to extract a person images having a similarity higher than certain threshold. Travel time is calculated by sorting information (camera identifier, time) attached to person images on a timeline, and the system detects gap between periods that the person appears in frame.

Abstract: An image search system comprising an video taking unit that takes a video, a search unit that contains a processor and a storage unit and searches for an image contained in the video, an input unit that receives information that is input to the search unit, and a display unit that displays information that is output from the search unit. The storage unit holds information indicating the shapes of trajectories that represent the travel paths of a plurality of moving objects extracted from the video. When information indicating the shape of a trajectory is input from the input unit, the search unit searches the plurality of moving-object trajectories held in the storage unit for trajectories that are similar to the input trajectory shape, and if such a trajectory is found, the search unit displays, on the display unit, images of the moving objects that have traveled along the found trajectories.
