… present an effective and efficient approach for low-light image enhancement, named Lookup Table Global Curve Estimation (LUT-GCE).
In contrast to existing curve-based methods with pixel-wise adjustment, … propose to estimate a global curve for the entire image that allows corrections for both under- and over-exposure.
… develop a novel cubic curve formulation for light enhancement, which enables an image-adaptive and pixel-independent curve for the range adjustment of an image.
… propose a global curve estimation network (GCENet), a very light … with … 25.4k parameters. To … speed … inference … lookup table … is employed for fast retrieval.
In addition, a novel histogram smoothness loss is designed to enable zero-shot learning, which is able to improve the contrast of the image and recover clearer details.
… approach outperforms the state of the art in terms of inference speed, especially on high-definition images (e.g., 1080p and 4k).
