Optical flow calculation algorithms are hard to implement on hardware level in real-time due to their complexity and high computational load. In this work, we present a novel hierarchical block matching based optical flow algorithm. The algorithm estimates the initial optical flow with block matching based methods, and refines the vectors with local smoothness constraints in each hierarchy level....
Live results obtained from the first real-time high-resolution free viewpoint synthesis hardware that utilizes three-camera disparity estimation are presented. The proposed hardware generates high-quality free viewpoint video at 55 frames per second on a Virtex-7 FPGA at a 1024×768 XGA video resolution for any horizontally-aligned arbitrary camera positioned between the leftmost and rightmost physical...
The recent development of high-quality free viewpoint synthesis algorithms and their implementations allows to realize glasses-free 3D perception. Although many algorithms have been developed in this domain, the real-time hardware realization of a free viewpoint synthesis for real-world images is challenging due to its high computational load and memory bandwidth requirements. In this paper, the first...
This paper proposes a hardware-oriented trinocular adaptive window size disparity estimation (T-AWDE) algorithm and the first real-time trinocular disparity estimation (DE) hardware that targets high-resolution images with high-quality disparity results. The proposed trinocular DE hardware is the enhanced version of the recently published binocular AWDE implementation. The T-AWDE hardware generates...
Omnidirectional stereoscopy and depth estimation are complex problems of image processing to which the Panoptic camera offers a novel solution. The Panoptic camera is a biologically-inspired vision sensor made of multiple cameras. It is a polydioptric system mimicking the eyes of flying insects where multiple imagers, each with a distinct focal point, are distributed over a hemisphere. Recently, the...
