MedSigLIP
Encoder Medico Immagine-Testo per Classificazione Zero-Shot
Modello encoder specializzato per comprendere e classificare immagini mediche con descrizioni testuali, senza necessità di training specifico.
About MedSigLIP
MedSigLIP MedSigLIP is a lightweight 400M parameter dual-tower encoder (vision + text) that supports 448×448 images and up to 64-token text inputs. Released on July 9, 2025, as part of Google's Health AI Developer Foundations project.
The model is trained on diverse medical imaging data including chest X-rays, dermatology, ophthalmology, pathology slides, and CT/MRI scans along with their corresponding reports. Natural images are also included to maintain generalization capabilities.
MedSigLIP is specifically designed for data-efficient classification, zero-shot classification, and semantic image retrieval tasks. For text generation tasks, Google recommends using MedGemma instead.
