METHOD FOR REMOVING THE EFFECTS OF PARTICULATE MATTER FROM SEQUENCES OF IMAGES

Imaging devices often obtain images of a scene in which portions of the scene are obscured by particles that are interposed between the scene and the camera such as those images obtained when looking through falling snow or through particles stirred up by water currents in an underwater domain.

Zusammenfassung:	Imaging devices often obtain images of a scene in which portions of the scene are obscured by particles that are interposed between the scene and the camera such as those images obtained when looking through falling snow or through particles stirred up by water currents in an underwater domain. An improved system for reducing the effects of those particles on reconstructed images of a scene consists of obtaining a number of images of a scene and replacing missing elements of the scene, which elements are ones obscured by the particles, with corresponding elements of the scene obtained from previous or following images in which those particular elements of the scene are visible. In this manner, a reconstructed invade of the scene can be obtained in which the effects of the particles on the image is greatly reduced.
