Abstract(ENG)

We present a framework that improves the performance of deep learning-based object detection model for generated images including game scenes. In particular, we aim to verify that the additional training using images sampled from game scenes can improve the performance of the object detection model, which was pre-trained using photographs. Among the various object detection schemes including Yolo V1, Yolo V2 and SSD, we employ YoloV2 model, which is one of the most widely used deep learning-based object detection model. YoloV2 model is pretrained using diverse photographs. This model is further trained through 160 game scene images sampled from eight different kinds of games. We select the games that range from realistic scenes and highly deformed scenes. We measure IoU (intersection over union) and accuracy using this model. The comparison between our re-trained model and the original model demonstrates the effectiveness of our strategy.
