Abstract (in Japanese) (See Japanese page) 
(in English) We propose an image-based rendering method called ”layered probability mapping.” The algorithm
requires modest computer power but produces high-quality output images even from textureless or
noisy input images. This accommodates ambiguities regarding object depth. Because the layers
are locally view dependent, we can save the computing time to acquire globally consistent precise
models. Also, by integrating the layers estimated from plural reference viewpoints, the rendered
image that include occlusion regions are much improved, since the region with low fidelity estimated
from one viewpoint is complemented by high fidelity from other viewpoints. The algorithm
that implements the features above is computationally modest and straight forward, without including
conditional branching and optimization of non-linear equations. Actually, by adding some
limitations, real-time rendering is possible by current commodity hardware. Also, we show the
image synthesis results to prove our method can generate higher quality images compared to some
conventional methods.
