Fingerprint Liveness Detection

• Designed a hand-crafted feature called Ridge-Slope-Valley feature to sample more information compared with previous works. Submitted to an EI indexed conference.
• Concluded some statistical features into a new framework, proposed some techniques to promote the performance of the framework. Paper Link

Aircraft Docking System

• System architecture construction, including submodule scheduling, message process, COM and TCPIP communication and parameter configuration.
• Laser point cloud processing algorithm design and test. It includes calibration, coordinate transformation, active tracking and signal processing.
• Machine Vision algorithm design, exploit and test. It includes moving object detection, airplane engine detection and tracking, airplane front wheel detection and tracking. 3 Chinese patents applied.
• Video demonstration.
