Panorama Stitching

Computer Vision | Tongji Univ. SSE Course Project


Background

Sometimes, when capturing, we can only get a partial image of the object, especially when the size of the object is extremely large. However, if the two partial images have some content overlapping, we can make use of CV algorithms to "stitch" them together to get a panorama of the scene. This is exactly the purpose of this project.
