New hue-split model trees improve cross-camera RGB mapping accuracy

Researchers have developed a novel hue-split model-tree method to improve cross-camera RGB mapping, addressing inconsistencies caused by differing sensor sensitivities and image processing pipelines. This approach recursively partitions the color space based on hue, assigning a unique affine color correction matrix (CCM) to each node in the tree. To ensure smooth transitions and prevent visual artifacts, the method incorporates a boundary-continuous formulation that blends predictions from multiple CCMs along a path from the root to a leaf node. Experiments demonstrated that this technique significantly reduces log-RMSE and enhances accuracy compared to traditional global CCMs, particularly when mapping between a Canon EOS-1Ds Mark II and a Canon EOS 20D using the Middlebury Registered Color Checker dataset.
