Minyoung Kim, Senior Research Engineer at Panasonic Silicon Valley Laboratory, presents the "A Fast Object Detector for ADAS using Deep Learning" tutorial at the May 2017 Embedded Vision Summit.
Object detection has been one of the most important research areas in computer vision for decades. Recently, deep neural networks (DNNs) have led to significant improvement in several machine learning domains, including computer vision, achieving the state-of-the-art performance thanks to their theoretically proven modeling and generalization capabilities. However, it is still challenging to deploy such DNNs on embedded systems, for applications such as advanced driver assistance systems (ADAS), where computation power is limited.
Kim and her team focus on reducing the size of the network and required computations, and thus building a fast, real-time object detection system. They propose a fully convolutional neural network that can achieve at least 45 fps on 640×480 frames with competitive performance. With this network, there is no proposal generation step, which can cause a speed bottleneck; instead, a single forward propagation of the network approximates the locations of objects directly.
