Action recognition learning device, action recognition learning method, action recognition device, and program

摘要

We can learn the action recognizer which can recognize the action with high accuracy with a small amount of learning data.Input section 101 isLearning video andAccepts behavior labels and behavior inputDetection unit 102About each frame image included in the learning imageA plurality of objects included in the frame image are detectedThe direction calculator 103 isOf the detected multiple objectsCalculate the direction of a reference object, which is a reference objectThe normalization section 104A reference object andThe positional relationship with other objects is a predetermined relationshipNormalize the learning imageThe optimization section 106 isBehavior estimated by inputting a learning image normalized to a behavioral recognizer to estimate the behavior of an object in an input videoBased on behavior labels behaviorOptimize the behavior of the behavioral recognizer.Diagram
