Snakes in a Plant: 3D Reconstruction of Foliage using Tethered Active Contours

Abstract

We present a novel method for reconstructing 3D models of foliage from a pair of images. Leaves are especially challenging objects to reconstruct in natural settings because of the lack of distinct features. We present a novel method for simultaneously growing contours to detect leaf boundaries. We then compute the transformation between the leaves to generate disparity maps. We demonstrate the effectiveness of our method on challenging instances where standard reconstruction methods fail.
