Three dimensional (3D) vision applications have drawn more attention nowadays and many products are entering the mass market. View interpolation is a crucial step to generate intermediate viewpoints from reference images. However, it is still challenging to achieve good performance in both processing speed and image quality for various 3D applications. In this paper, a hardware-compatible view interpolation...
In tele-presence systems, direct face-to-face contact, is essential for emotional communication as it carries non-verbal clues. In commercial products, face-to-face contact is approximated by using either a large semi-transparent mirror to project an image of the remote participant and capture the local participant image by using a video camera aiming at the centre of the screen or by using low profile...
This paper presents an efficient hardware architecture to perform the real-time correction of the barrel distortion in wide-angle cameras. Applied to the single-sensor cameras employing the Bayer pattern as the color filter array (CFA), the proposed architecture performs the backward mapping process once for each pixel location in the Bayer pattern and the sub-pixel image resampling process for each...
