ROBUST FRAME REGISTRATION FOR MULTI-FRAME IMAGE PROCESSING

Abstract: a method includes obtaining, using at least one processing device of an electronic device, multiple image frames capturing a scene. the method also includes selecting, using the at least one processing device, a reference frame among the image frames. the method further includes aligning, using the at least one processing device, each of one or more non-reference frames among the image frames with the reference frame by (i) performing tile-based registration of the non-reference frame to the reference frame, (ii) performing feature-based registration of the non-reference frame to the reference frame, (iii) aggregating first motion vectors generated during the tile-based registration and second motion vectors generated during the feature-based registration, and (iv) warping the non-reference frame based on the aggregated motion vectors to generate an aligned non-reference frame. the reference frame and the one or more aligned non-reference frames may be blended to generate a final image of the scene.
