Title

Real-Time Visual Tracking by Convolutional Neural Networks


Abstract

Recent tracking algorithms based on convolutional neural networks achieve impressive accuracy, and MDNet is one of the seminal works among them. However, there are still many remaining issues, especially in terms of efficiency. I present a novel real-time visual tracking algorithm based on MDNet, where feature extraction time is significantly reduced by RoIAlign operations and a novel discriminative instance embedding loss is integrated in the pretraining stage to improve accuracy. The proposed real-time MDNet runs at approximately 50 frames/second with almost same accuracy with MDNet. Contrary to many existing approaches, our algorithm works very well on various datasets without dataset sensitive parameter tuning.
