David Chienyun Liu, 18, from Saratoga, created a system to search digital images for his Intel Science Talent Search computer science project. What began as David's effort to organize the family photo album grew into software that searches images automatically by linking visual cues with concepts (called semantic concept models), such as trees and buildings, to improve retrieval precision by 22%. Then, using a spring graph, he created an interactive exploration system that can effectively group conceptually similar images. Working from home, he tested the system by examining aerial images that he obtained from NASA to identify hazards to buried oil pipelines and achieved a 96% recognition rate. David speculates that this technology can be used in real time by unmanned aerial vehicles to safeguard pipelines and other valuable resources. At Lynbrook High School in San Jose, David is co-president of the robotics team and founder of the computer club. A multiple award winner at Intel ISEF competitions, he enjoys piano, tennis and Web development. David hopes to study computer science at Stanford or MIT and is the son of Hui Liu and Kathleen Lin.
