A PDE-based log-agnostic illumination correction algorithm
This is an incremental improvement for image processing applications, offering an alternative method for illumination correction without relying on logarithmic functions.
The paper tackled the problem of dynamic range compression and illumination correction in images without using logarithmic functions, by proposing a PDE-based algorithm that combines forward and reverse flows, and reported comparable performance to existing methods in most cases.
This report presents the results of a partial differential equation (PDE)-based image enhancement algorithm, for dynamic range compression and illumination correction in the absence of the logarithmic function. The proposed algorithm combines forward and reverse flows in a PDE-based formulation. The experimental results are compared with algorithms from the literature and indicate comparable performance in most cases.
