About the Project

Most prior art image fusion algorithms are based on two assumptions. First, N-channel input images (e.g. the N=4 channel R, G, B and near-infrared) are fused into a single channel equivalent fused image [1]. And, second, that – other than the fused data capturing all the detail of the channels – there is not a simple structural relationship between the fused image and any of the N-channel input images.

In this PhD project, the successful candidate will develop a guided colour image fusion algorithm that maps N-channel images to M-channels (where M<N and is typically 3 i.e. a colour image). Further, the fused image will be guided by the structure in the original colour image. For the RGB+NIR example, the fused image will ‘look like’ the original image but with some extra detail composited from the NIR channel. The prior art “spectral edge” image fusion algorithm [2] can be viewed as a guided colour image fusion algorithm but, there, the concept of guide is at a very low level. The project will develop image fusion algorithms based on higher level semantic concepts including image relighting [3] and semantic decompositions [4]. The image fusion research will take place in the context of the wider ‘Future Colour Imaging’ project [5].

The successful candidate will join the Colour & Imaging Lab (the C&IL) in the School of Computing Sciences at UEA. The C&IL is one of our largest labs and currently comprises 10 PhD students and 3 postdoctoral fellows.

Funding Notes

This PhD project is UEA funded studentship covering stipend (£15,609 pa in 2021-22), tuition fees (Home only) and research costs. International applicants (EU/non-EU) are eligible for UEA funded studentships but they are required to fund the difference between Home and International tuition fees (which for 2021-22 are detailed on the University’s fees pages at
