Robust detection of a reference image during major photometric transformations |
摘要 |
The present invention pertains to a method and a system for identifying a specific image within a flow of images. The system calculates a reference index of the specific image, and current indexes of the current images of said flow. The index has the form of an ordered and finite set of values encoding the content of the current image. The system also compares the reference index with the current index of the current image of the monitored flow. It is thus possible to detect a specific image within a flow with great precision and extremely fast while being robust during major photometric alterations.
