Multi-view representation and synthesis for 3D object movie

An object movie can provide viewers with a capability of seeing a 3-D object from any viewpoint. To achieve the best resolution, it needs many cameras to capture views simultaneously. This is however not cost-effective. To solve this problem, we take photographs around the object in a constant angle interval. After this, the object movie system is constructed in a manner of viewpoint synthesis from originally captured images. To further reduce the data requirements of the object movie, we propose a method to retain effective regions in each captured image. Only the retained regions are used to synthesize the resulting virtual views. Experiments show that our algorithm can synthesize virtual views better and faster than previous methods. The results also show that when an object movie is constructed from camera views with 10-degrees of angle interval, the effective region selection can reduce about 40% of pixels in multi-view representation while also keeping good synthesized quality.
