Abstract:
This paper presents a Diminished Reality system that is able to propagate textures as well as structures with
a low computational cost, almost in real-time. An existing inpainting algorithm is optimized in order to
reduce the high computational cost by implementing some Computer Vision techniques. Although some of
the presented optimizations can be applied to a single static image directly, the global system is mainly oriented
to video sequences, where temporal coherence ideas can be applied. Given that, a novel pipeline is proposed
to maintain the visual quality of the reconstructed image area without the need of calculating everything again
despite slow camera motions. To the best of our knowledge, the prototype presented in this paper is the
only Diminished Reality system focused on structure propagation that works near real-time. Apart from the
technical description, this paper presents an extensive experimental study of the system, which evaluates the
optimizations in terms of t
ime and quality.
