Video Processing for Multiview Multimodal Camera Systems

Free viewpoint (multiview) video aims at enabling virtual navigation in a dynamic 3D scene from

arbitrary camera locations and orientations. The associated technologies also signify the solution to

the problem of providing genuinely immersive U+201Classes-freeU+201D3D media, offering not only stereopsis,

but also motion parallax. Capturing high-quality multiview content from real-world scenes is an

enormous challenge, requiring a huge number of views from finely spaced angles. Unavoidably, the

number of captured views is much lower than what required thus, the missing views need to be

estimated. However, such view synthesis needs to account for the distances between objects and

cameras, complex 3D structure, illumination changes and non-Lambertian reflectance, none of

which are captured directly by single cameras. Existing solutions based on stereo or sparse

multiview camera setups fail to deliver acceptable 3D video quality. To solve this problem, we

propose a fundamental paradigm shift, focusing on multiview multimodal camera systems that

combine depth sensors and colour cameras of various spatial resolutions. Multimodal systems are

more versatile than linear camera arrays, thereby posing significant research challenges. The goal of

the project is to substantially advance over the state-of-the-art on multiview depth estimation and

view synthesis by designing radically new algorithms inspired by the new theoretical framework of

compressed sensing with side information.
