On User-Interaction in 3D Reconstruction

Abstract

For many computer graphics tasks such as segmentation, tracking or retargeting, algorithms are designed to allow user interaction. For real-world applications, tools which give users some form of control are often preferred over fully automatic ones. In 3D reconstruction, however, algorithms are typically non-interactive and errors are corrected after reconstruction in generic 3D modeling software. In this contribution, we discuss fundamental algorithmic considerations regarding interactivity in 3D reconstruction and we outline an optimization-based reconstruction framework which allows the incorporation of interactive tools as energy terms.
