Image Registration

Automatic image or video frame registration

Computer Vision System Toolbox™ algorithms enable automatic image registration. These algorithms use features to estimate the geometric relationships between images or video frames. Typical uses include video mosaicking, video stabilization, image fusion, and 3-D vision.
