Detecting an image obstruction
Publication/Patent Number: US10547801B2 Publication Date: 2020-01-28 Application Number: 15/794,103 Filing Date: 2017-10-26 Inventor: Cheaz, Nixon   Diaz, Anthony   Shetty, Rohit   Gebhardt, Richard A.   Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION   IPC: H04N5/357 Abstract: Detection of an image obstruction is facilitated by, in part, obtaining multiple frames of an image being captured via an imaging device, and confirming movement of the imaging device between the multiple frames. The movement causes perspective shifting of the image between frames and the perspective shifting results in one or more objects of the image shifting between frames. The detection process determines whether an edge object within the multiple frames does not shift in a manner corresponding to the one or more objects between the multiple frames, and based, at least in part, on determining that the edge object does not shift in the corresponding manner to the one or more objects, identifying the edge object as an image obstruction. Presence of the identified image obstruction is signaled to facilitate corrective action being taken.
