Left: Comparison of runtime for the VEViD and the Zero-DCE algorithms for a range of image sizes. VEViD is capable of processing 4K resolutions images (8,294,440 Mega pixels) at 24 FPS and scales much better with frame size. The VEViD approximation developed for computational acceleration is even faster with capability of processing 4K resolution frames at more than 200 FPS. The approximation is a closed-form equivalent-model of the numerical VEViD algorithm that avoids the Fourier transform operations. Right: Comparison of Zero-DCE (middle) and VEViD (bottom) for two diverse input images (top). VEViD Parameters for the pedestrian and lamp images: S = 0.2, b = 0.16, G = 1.4 and S = 0.2, b = 0.32 G = 1.4, respectively
