Patent number: 10895911Abstract: An image operation method and system for obtaining an eye's gazing direction are provided. The method and system employ multiple extraction stages for extracting eye-tracking features. An eye frame is divided into sub-frames, which are then sequentially temporarily stored in a storage unit. Launch features of sub frames are sequentially extracted from the sub frames by a first feature extraction stage, where a data of a former sub-frame is extracted before a data of a latter sub-frame is needed to be stored. Next, the remaining feature extraction stages apply a superposition operation on the launch features to obtain terminal features, which are then computed to obtain an eye's gazing direction.Type: GrantFiled: March 12, 2019Date of Patent: January 19, 2021Assignee: National Taiwan UniversityInventors: Shao-Yi Chien, Yu-Sheng Lin, Po-Jung Chiu
