Experts-Guided Unbalanced Optimal Transport for ISP Learning from Unpaired and/or Paired Data
PositiveArtificial Intelligence
- A new framework for Learned Image Signal Processing (ISP) has been introduced, utilizing Unbalanced Optimal Transport (UOT) to facilitate training from both unpaired and paired datasets. This approach addresses the significant challenge of acquiring large-scale paired raw-to-sRGB datasets, which has been a bottleneck in the field. The framework incorporates a committee of expert discriminators to enhance the mapping process by providing targeted gradients.
- This development is crucial as it allows for more robust ISP training, reducing dependency on costly paired data while improving performance in real-world applications. The ability to effectively handle outliers in target sRGB data further enhances the framework's utility, potentially leading to advancements in various image processing tasks.
- The introduction of UOT in ISP learning aligns with ongoing efforts to innovate within the field of artificial intelligence, particularly in generative modeling and image restoration. Similar methodologies are being explored across various domains, such as single-image super-resolution and reinforcement learning, indicating a trend towards more efficient and adaptable training frameworks that can operate under diverse conditions.
