Researchers have introduced UBLLIE, a novel unsupervised framework designed to enhance both backlit and low-light images. This method does not require paired ground-truth data, instead utilizing CLIP-guided prompt learning for semantic supervision. The framework employs a U-Net backbone with Atrous Spatial Pyramid Pooling to capture multi-scale context, enabling adaptive correction for uneven illumination. Experiments on various datasets show UBLLIE outperforms existing supervised and unsupervised techniques in fidelity, perceptual quality, and generalization, while also highlighting the need for improved benchmarking in backlit image enhancement.
