About

C. Coelho’s research lies at the intersection of computer vision and scene understanding, with a particular focus on geometric inference from natural images. In a seminal 1993 paper, "Extraction of vanishing points from images of indoor and outdoor scenes," Coelho introduced robust methods for automatically identifying vanishing points—a foundational task for 3D reconstruction, camera calibration, and spatial layout analysis. This work, which has garnered 44 citations, demonstrated how vanishing point extraction could be reliably performed across diverse environments, from cluttered indoor spaces to complex outdoor landscapes, overcoming challenges like texture noise and perspective distortion. Coelho’s contributions provided early, practical algorithms that influenced subsequent developments in autonomous navigation, augmented reality, and architectural modeling. By bridging theoretical geometry with real-world imagery, Coelho helped lay the groundwork for modern scene parsing and depth estimation techniques. Researchers and students in computer vision will find this work a clear, enduring example of how geometric cues can unlock rich spatial information from ordinary photographs.
