Alternatives to LightlyStudio
LightlyStudio brings computer-vision dataset work under one roof, combining curation, annotation, quality assurance, evaluation, and management. It computes embeddings and supports similarity search, deduplication, outlier detection, and class balancing. Teams can annotate images and video, use model-assisted labeling, evaluate models with a confusion matrix and per-sample metrics, and manage datasets through a Python API. Its open-source version is free, and it runs locally…
