Image Registration

Automatic image or video frame registration

Start Here

Computer Vision System Toolbox™ supports automatic image registration by providing algorithms that 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.
