Segmentation-based Seam Cutting for High-Resolution 360-degree Video Stitching

High-resolution 360 Video Foveated Stitching for Real-time VR

In virtual reality (VR) applications, the contents are usually generated by creating a 360◦video panorama of a real-world scene. Although many capture devices are being released, getting high-resolution panoramas and displaying a virtual world in realtime remains challenging due to its computationally demanding nature. In this paper, we propose a real-time 360◦video foveated stitching framework...

Virtual displays for 360-degree video

In this paper we describe a novel approach for comparing users' spatial cognition when using different depictions of 360degree video on a traditional 2D display. By using virtual cameras within a game engine and texture mapping of these camera feeds to an arbitrary shape, we were able to offer users a 360-degree interface composed of four 90-degree views, two 180-degree views, or one 360-degree...

Seam-Driven Image Stitching

Image stitching computes geometric transforms to align images based on the best fit of feature correspondences between overlapping images. Seam-cutting is used afterwards to to hide misalignment artifacts. Interestingly it is often the seam-cutting step that is the most crucial for obtaining a perceptually seamless result. This motivates us to propose a seam-driven image stitching strategy wher...

360-Degree Video Head Movement Dataset

While Virtual Reality applications are increasingly attracting the attention of developers and business analysts, the behaviour of users watching 360-degree (i.e. omnidirectional) videos has not been thoroughly studied yet. This paper introduces a dataset of head movements of users watching 360-degree videos on a Head-Mounted Display (HMD). The dataset includes data collected from 59 users watc...
