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.
