Accurate non-iterative depth layer extraction algorithm for image based rendering

James Pearson, Pier Luigi Dragotti, Mike Brookes

Abstract: Image based rendering is an attractive alternative for generating novel views compared to model based rendering due to its lower complexity and potential for photo-realistic results. We present a fast unsupervised method for synthesising arbitrary viewpoints of a scene from a set of existing views. Our novel improvements include optimising the placement of depth layers to take advantage of the composition of real world scenes and hierarchically building our simple geometric model to maximise its accuracy.
