Glue Factory is a training and evaluation library for deep neural networks focused on local feature detection and matching in computer vision. It supports reproducibility of state-of-the-art models like LightGlue and GlueStick, enables multi-dataset training with custom local features or lines, and provides evaluation on standard benchmarks like HPatches and MegaDepth-1500. Built on PyTorch, the library includes auto-downloaders for models and datasets.
