    A unique imaging modality based on Equal Thickness Contours (ETC) has introduced a new opportunity for 3D shape  reconstruction from multiple views. We present a computational framework for representing each view of an object in terms of its object thickness and then integrating these representations into a 3D surfaces by algebraic reconstruction. The object thickness isinferred by grouping curve segments that correspond to the second derivative maxima. At each step of the process, we use some form of regularization to ensure closeness to the original features as well as neighborhood continuity. We apply our approach to images of a sub-micron crystal structure obtained through a holographic process.
