Method and system for controlling an image processing flow

A method for controlling an image processing flow, comprising: receiving a plurality of graph application programming interface (API) calls to add nodes to respective subgraphs; receiving a given graph API call to add a control flow node to a main graph, wherein the given graph API call identifies the subgraphs as parameters, and wherein the main graph includes the control flow node connected to other nodes by edges that are directed and acyclic; compiling, by a graph compiler, the main graph and the subgraphs into corresponding executable code; evaluating a condition at runtime before executing the subgraphs identified in the given graph API call; and executing, by one or more target devices, the corresponding executable code to perform operations of an image processing pipeline while skipping execution of one or more of the subgraphs depending on the condition.
