Panorama to Cube:
A Content-aware Representation Method
Panorama to Cube
for Innovative Display
As panoramas provide a brand new viewpoint for the public, relevant cameras and software such as RICOH Theta, Microsoft Photosynth are embracing more and more users. However, the display methods for panoramas remain monotonous.
In this project, we propose a novel representation method called Content-Aware Cube Unwrapping using the effective and interactive techniques of
-
orientational rectification
-
line detection
-
vanishing point estimation
-
-
salient detection
-
weighed combination of energy of intensity, entropy and color
-
optimization clues: exposure and face detection
-
-
panorama unwrapping
-
fold line estimation
-
different mapping methods
-
-
visual enhancement
-
seam carving and inserting to enhance the key content
-
Thus, a number of fascinating applications will come into reality. We are able to realize content-ware panorama unwrapping on arbitrary 3D shapes.
For instance, six surfaces of a Rubiks cube can be automatically rendered from a vertically oriented panorama, without cutting any person or significant object apart. More types of polyhedron and 3D printing will be probable to get involved as well. Further research can be also combined with augmented reality displays.
