SynthVal: A Framework for Validating Synthetic Medical Images

A Python framework for validating synthetic medical image quality through statistical comparisons in deep feature space. Uses transformer-based models to extract semantic embeddings and computes Fréchet Distance, Wasserstein Distance, and KL Divergence between real and synthetic distributions. Evaluated on the CSAW-CC mammography dataset with images from the Barcelona Supercomputing Center.
