ZeST is an image material transfer technology co-developed by the research teams of the University of Oxford, Stability AI, and MIT CSAIL. It enables the transfer of materials from one image to another object without any prior training. ZeST supports single material transfer and can handle multi-material editing within a single image. Users can easily apply one material to multiple objects in an image. In addition, ZeST also supports fast image processing on devices, eliminating the dependence on cloud computing or server-side processing, significantly improving efficiency.
