The bidirectional texture function (BTF) is a 6D function that can describe textures arising from both spatially-variant surface reflectance and surface mesostructures. In this paper, we present an algorithm for synthesizing the BTF on an arbitrary surface from a sample BTF. A main challenge in surface BTF synthesis is the requirement of a consistent(More)

Recently, differential information as local intrinsic feature descriptors has been used for mesh editing. Given certain user input as constraints, a deformed mesh is reconstructed by minimizing the changes in the differential information. Since the differential information is encoded in a global coordinate system, it must somehow be transformed to fit the(More)
This paper presents a novel approach for establishing vertex correspondences between two planar shapes. Correspondences are established between the perceptual feature points extracted from both source and target shapes. A similarity metric between two feature points is defined using the intrinsic properties of their local neighborhoods. The optimal(More)
We present an easy-to-use image retouching technique for realistic reshaping of human bodies in a single image. A <i>model-based</i> approach is taken by integrating a 3D whole-body morphable model into the reshaping process to achieve globally consistent editing effects. A novel <i>body-aware image warping</i> approach is introduced to reliably transfer(More)
We introduce a <i>contextual descriptor</i> which aims to provide a <i>geometric</i> description of the <i>functionality</i> of a 3D object in the context of a given scene. Differently from previous works, we do not regard functionality as an abstract label or represent it implicitly through an agent. Our descriptor, called <i>interaction context or(More)
Depth camera such as Microsoft Kinect, is much cheaper than conventional 3D scanning devices, and thus it can be acquired for everyday users easily. However, the depth data captured by Kinect over a certain distance is of extreme low quality. In this paper, we present a novel scanning system for capturing 3D full human body models by using multiple Kinects.(More)
Figure 1: The co-segmentation result of the Candelabra set by our algorithm. Starting from the over-segmented patches of the shapes (left), our algorithm automatically obtains the consistent segmentations among these objects by grouping the patches using subspace clustering in multiple feature spaces. Corresponding parts are shown in the same colors(More)
