(LaTeX) Abstract:

We address the problem of partial symmetry detection, i.e., the identification of building blocks a complex shape
is composed of. Previous techniques identify parts that relate to each other by simple rigid mappings, similarity
transforms, or, more recently, intrinsic isometries. Our approach generalizes the notion of partial symmetries to
more general deformations. We introduce subspace symmetries whereby we characterize similarity by requiring
the set of symmetric parts to form a low dimensional shape space. We present an algorithm to discover subspace
symmetries based on detecting linearly correlated correspondences among graphs of invariant features. The detected
subspace symmetries along with the modeled variations are useful for a variety of applications including
shape completion, non-local and non-rigid denoising. We evaluate our technique on various data sets. We show
that for models with pronounced surface features, subspace symmetries can be found fully automatically. For
complicated cases, a small amount of user input is used to resolve ambiguities. Our technique computes dense
correspondences that can subsequently be used in various applications, such as model repair and denoising.
