The Heat Kernel Signature (HKS) is a mathematical and geometric concept used primarily in the field of shape analysis and computer graphics. It provides a way to describe and analyze the intrinsic properties of shapes, particularly in 3D geometry. The HKS is related to the heat diffusion process on a manifold; it's derived from the heat kernel, which describes how heat propagates through a space over time.
