Photographs usually show a scene from a single perspective. However, as commonly seen in art, scenes and objects
can be visualized from multiple perspectives. Making such images manually is time consuming and tedious. We
propose a novel system for designing multi-perspective images and videos. First, the images in the input sequence
are aligned using structure from motion. This enables us to track feature points across the sequence. Second,
the user chooses portal polygons in a target image into which different perspectives are to be embedded. The
corresponding image regions from the other images are then copied into these portals. Due to the tracking feature
and automatic warping, this approach is considerably faster than current tools. We explore a wide range of artistic
applications using our system with image and video data, such as looking around corners and up and down stair
cases, recursive multi-perspective imaging, cubism and panoramas.
