The offline image segmentation SDK uses advanced detection technology to precisely separate a subject from the background in an image. This enables flawless background removal and replacement, even in complex scenes.
As of May 12, 2026, the Alibaba Cloud Vision Intelligence Platform will no longer issue new license authorizations for its offline SDK products. Existing users can continue to use their licenses without interruption.
