3d Lut

3D Lookup Tables (LUTs) are efficient computational tools for real-time image enhancement, offering a fast alternative to computationally intensive neural networks. Current research focuses on improving the accuracy and adaptability of 3D LUTs through techniques like contrastive learning, attention mechanisms, and adaptive sampling strategies, often incorporating them into novel architectures such as neural implicit LUTs and 4D LUTs to handle more complex image transformations. This work is significant because it enables high-speed image processing on resource-constrained devices like smartphones and embedded systems, impacting applications ranging from mobile photography to real-time video processing.
