1. A method for analyzing video data to determine manufacturing waste to optimize productivity, the method comprising:
identifying, by a productivity assessment computing device, a plurality of entities present in each of a plurality of obtained frames of a video and a type of each of the plurality of entities; plotting, by the productivity assessment computing device, movement of each of the plurality of entities across at least a subset of the frames to obtain a trajectory of each of the plurality of entities; identifying, by the productivity assessment computing device, a plurality of interactions of one or more of the plurality of entities in each of the plurality of frames; generating, by the productivity assessment computing device, a unique sequence encoding for each of a plurality of subtasks performed by each of the plurality of entities, wherein the subtasks are identified based on the interactions and a sequence of at least a subset of the subtasks is associated with at least one task; classifying, by the productivity assessment computing device, at least one of the subset of subtasks as a waste subtask of the task based on one or more of the interactions corresponding to the one of the subset of subtasks and the trajectory and the type of each of the plurality of entities associated with the one or more of the interactions; correlating, by the productivity assessment computing device, the sequence encodings of the one of the subset of subtasks with a number of frames per second of the video to determine at least one waste duration value for the task; and outputting, by the productivity assessment computing device, the waste duration value. |
