Sample videos of real-time mosaicing using SAM

These videos show real-time mosaicing of webcam videos

• Office - real-time mosaic. SAM generates a mosaic frame-by-frame as the camera pans and tilts freely. Note the slight visible error by the end of the sequence: the centre of rotation is about 10 cm from the optical centre so the estimated projective transforms do not precisely model the frame-to-frame differences. SAM revises an area in the mosaic when it is revisited, but does not do global re-adjustments.
• Garden - real-time mosaic The revisits in this video need less correction because the scene is far away relative to the distance between the optical centre and centre of rotation.
• Tower - real-time mosaic of a buiding at York University. Monochrome frames are displayed when SAM cannot find a good match.
• House - real-time mosaic from jerky movement. Monochrome frames are displayed when SAM cannot find a good match.
• Plane - real-time mosaic by waving a camera over a plane. Arbitrary camera movement over a plane yields a projective transformation between images, so SAM can mosaic a plane from a freely-moved camera.
