Method of searching data to identify images of an object captured by a camera system
View Patent ↗A camera system comprises an image capturing device, object detection module, object tracking module, and match classifier. The object detection module receives image data and detects objects appearing in one or more of the images. The object tracking module temporally associates instances of a first object detected in a first group of the images. The first object has a first signature representing features of the first object. The match classifier matches object instances by analyzing data derived from the first signature of the first object and a second signature of a second object detected in a second image. The second signature represents features of the second object derived from the second image. The match classifier determine whether the second signature matches the first signature. A training process automatically configures the match classifier using a set of possible object features.
1. A method of searching data to identify images of an object captured by a camera system, the method comprising:
receiving image data representing a first object in an image of a field of view of the camera system, the first object having a first signature representing features of the first object;
displaying an image of the first object on a display;
accepting user input indicative of a selection of the first object;
making determinations as to whether the first signature matches one or more signatures of a group that correspond to a set of objects captured in images of the field of view; and
sending a notification indicating a match between the first signature and a second signature of a second object of the set.
2. The method of claim 1 , in which the notification includes displaying an image of the second object on the display.
3. The method of claim 1 , in which the camera system includes first and second image capturing devices connected to one another and the display a network, the first and second image capturing devices having, respectively, a first field of view and a second field of view, the field of view of the camera system corresponding to the first field of view and the second field of view in combination, further comprising:
capturing with the first image capturing device the image of the first object; and
capturing with the second image capturing device the images of the second object.
4. The method of claim 1 , in which the first object includes a fast signature representing a simplified version of the first signature, and the objects of the set include fast signatures representing simplified versions of the group of signatures, the method further comprising:
comparing the fast signature of the first object with the fast signatures of the objects of the set prior to making determinations as to whether the signatures of the group match the first signature.
5. The method of claim 1 , further comprising retrieving the group of signatures from a database.
6. The method of claim 1 , further comprising sending the notification when the second signature matches the first signature and when a selected rules violation is associated with the second object.
7. The method of claim 1 , in which a rule violation is associated with each of the objects of the set.
