L2S Talk by Prof Onofre Martorell (University of the Balearic Islands): Joint fusion and denoising for multi-exposure sequences

29 April 2024, 16-18 h in PB-H 0103

The talk is part of the ZESS lecture series and hosted by the DFG research unit “Learning to Sense” (L2S).

Sequences of images taken with different exposure time can be combined by both multi-exposure fusion (MEF) or high dynamic range (HDR) techniques. In both cases, information from all images of a sequence is combined in order to get an image with a higher amount of details on all areas of the selected reference image. This combination of information can also be used in combination with techniques so as to remove the existing noise on the images. In this presentation we will present two different techniques for joint multi-exposure sequence and denoising which exploit the redundancy of similar patches. The first one is a MEF technique for static images and the second one is a HDR technique applied on RAW data which is able to deal with ghosting artifacts.
