Described herein is a technology for facilitating multi-media collaboration. In some implementations, a digital image with hand drawings is provided at a local location of a collaboration. A graph is formed from the digital image. Connected components (CCs) in the graph are identified. Text CCs in the graph is classified. The text CCs from the graph is segmented. Objects and data of the text CCs are propagated to participants of the collaboration at other remote locations.

A computer-implemented smart recovery system for dynamic workflows addresses a change to a data object during execution of an instance of a workflow by selectively re-executing workflow tasks that are affected by the change, without cancelling the instance and restarting a new instance of the workflow. A determination of whether a task is to be re-executed during the smart recovery process may include examining a re-evaluation label assigned to the task.
