Of the 6.84
billion smart phones users in the world [How23], 40% regularly use their device
for capturing video and of these, 40% want better quality from smartphone video
recordings [Kni21]. Previous EPSRC research by Chalmers at WMG [EP1, EP2, EP3]
has shown how High Dynamic Range (HDR) video can provide higher quality video
because HDR imaging is able to capture the full range of
lighting in the scene; there are no more under- or over-exposed regions. HDR
video can be taken on modern mobile devices by capturing two or more different exposures
consecutively and merging these into a single HDR video frame [DM97, BAD*17].
However, ghosting artefact can occur as it takes time to capture the multiple
exposures for a single HDR frame and objects in the scene may move [KDC20].
Event
cameras are bio-inspired vision sensors [LPD08]. Instead of recording the
absolute scene intensity information, as in standard cameras, event cameras
record the time, spatial position, and the polarity of the events that occur
within the field-of-view of the camera. This has the potential for determining
exactly what the movement is in a scene.
This short
multidisciplinary EPSRC IAA proposal will maximise impact from previous WMG research
by:
1. Developing a
demonstrator of an HDR+Event video system
2. Showcasing the
demonstrator:
a. At the large
mobile phone exhibition, ITC, 7-11 June 2023
b. To key mobile
phone stakeholders and other interested parties, including BT and Vodaphone
(for which contacts already exist), at a workshop to be held at the University
of Warwick
3. Working closely
with Warwick Innovations to develop an Exploitation Plan for commercialisation
of the system
