About
Ian Chai is a researcher whose work sits at the intersection of computer vision, document analysis, and engineering informatics. His most notable contribution is the development of the "Orthogonal Zig-Zag" method, a highly efficient algorithm for extracting straight lines from complex engineering drawings. Introduced in his 1992 paper of the same name, this technique addressed a critical bottleneck in digitizing and processing technical diagrams, offering a robust and computationally light alternative to contemporary Hough transform-based approaches. While the paper has accumulated 16 citations, its true impact lies in its foundational role for subsequent work in raster-to-vector conversion and automated CAD reconstruction. Chai’s research is characterized by a focus on practical, real-world problems—specifically, how to bridge the gap between scanned paper documents and editable digital models. His work remains a reference point for scholars developing algorithms for line detection in noisy, domain-specific imagery, demonstrating that elegant, problem-specific solutions can outperform general-purpose methods in specialized tasks.
