    Abstract: A "Panoramic Viewfinder" provides an intuitive interactive viewfinder display operating on a digital camera display screen. This interactive viewfinder provides real-time assistance in capturing images for constructing panoramic image mosaics. The Panoramic Viewfinder "brushes" a panorama from images captured in any order, while providing visual feedback to the user for ensuring that desired scene elements will appear in the final panorama. This visual feedback presents real-time stitched previews of the panorama while capturing images. In one embodiment, the viewfinder display of the Panoramic Viewfinder includes a "mosaic preview" which presents a stitched mosaic preview of the captured images; a live display window representing a "current content" of the camera viewfinder, which is mapped to a matching location within the mosaic preview; and an optional panoramic "cropping frame" overlaid onto the mosaic preview which illustrates a section of the mosaic which will survive a rectangular cropping of the mosaic.

    Abstract: A "Keyframe Stitcher" provides an efficient technique for building mosaic panoramic images by registering or aligning video frames to construct a mosaic panoramic representation. Matching of image pairs is performed by extracting feature points from every image frame and matching those points between image pairs. Further, the Keyframe Stitcher preserves accuracy of image stitching when matching image pairs by utilizing ordering information inherent in the video. The cost of searching for matches between image frames is reduced by identifying "keyframes" based on computed image-to-image overlap. Keyframes are then matched to all other keyframes, but intermediate image frames are only matched to temporally neighboring keyframes and neighboring intermediate frames to construct a "match structure." Image orientations are then estimated from this match structure and used to construct the mosaic. Matches between image pairs may be compressed to reduce computational overhead by replacing groups of feature points with representative measurements.
