Authors: Jia Yu, Xinyu Zhou, Cong Yao, Jianan Wu, Chi Zhang, Shuchang Zhou

Description: The detection part is accomplished by a FCN which directly extracts text regions from original images. The tracker is a net flow based association algorithm.

Authors: Xu-Cheng Yin, Shu Tian, Ze-Yu Zuo, Wei-Yi Pei, Chun Yang

Description: Here, multi-orientation text detection is conducted with USTB_TexStar+ (USTB_TexStar [1,2] with multiple channels), and text tracking within a Bayesian framework is performed for improving detection results.

Authors: Hyung Il Koo and Yong Gyun Kim

Description: This text detection and tracking system was submitted by Hyung Il Koo and Yong Gyun Kim from Ajou University, Suwon, Korea. The system first extracts connected components (CCs) with the maximally stable extremal region (MSER) algorithm and finds word candidates by using the bottom-up grouping clustering method [1]. For each candidate region, we find corresponding regions in the other frames with the CSK trackers [2] and build chains. We also detect collisions between the chains and filter out non-promising ones.
