Implicit Shape Completion via Adversarial Shape Priors
CoRR, 2022 We present a novel neural implicit shape method for partial point cloud completion. To that end, we combine a conditional Deep-SDF architecture with learned, adversarial shape priors. More specifically, our network converts partial inputs into a global latent code and then recovers the full geometry via an implicit, signed distance generator ...

Experimental Analysis of Commercial Optical Methods for Foot Measurement
Sensors, 2022 Due to the increasing trend of online shopping, shoes are more and more often bought without being tried on. This leads to a strong increase in returns, which results in a high financial as well as ecological burden. To prevent this, feet can be measured

Sparse-to-Dense Multi-Encoder Shape Completion of Unstructured Point Cloud
IEEE Access, 2020 Unstructured point clouds are a representative shape representation of real-world scenes in 3D vision and graphics. Incompletion inevitably arises, due to the way the set of unorganized points is captured, e.g., as fusion of depth images, merged laser ...

Towards Precise Completion of Deformable Shapes [PDF]
, 2020 According to Aristotle, “the whole is greater than the sum of its parts”. This statement was adopted to explain human perception by the Gestalt psychology school of thought in the twentieth century. Here, we claim that when observing a part of an object which was previously acquired as a whole, one could deal with both partial correspondence and shape ...

3D Shape Completion with Test-Time Training
CoRRThis work addresses the problem of \textit{shape completion}, i.e., the task of restoring incomplete shapes by predicting their missing parts. While previous works have often predicted the fractured and restored shape in one step, we approach the task by separately predicting the fractured and newly restored parts, but ensuring these predictions are ...

Perceptual organization and visual awareness: the case of amodal completion
Frontiers in Psychology, 2023 We investigated the involvement of visual awareness in amodal completion, and specifically, whether visual awareness plays a differential role in local versus global completion, using a primed shape discrimination paradigm and the color-opponent flicker ...

2-D shape completion with shape priors [PDF]
Chinese Science Bulletin, 2013 We propose new techniques for 2-D shape/contour completion, which is one of the important research topics related to shape analysis and computer vision, e.g. the detection of incomplete objects due to occlusion and noises. The purpose of shape completion is to find the optimal curve segments that fill the missing contour parts, so as to acquire the ...

Separate cortical stages in amodal completion revealed by functional magnetic resonance adaptation [PDF]
, 2007 Background: Objects in our environment are often partly occluded, yet we effortlessly perceive them as whole and complete. This phenomenon is called visual amodal completion.

DiffComplete: Diffusion-based Generative 3D Shape Completion [PDF]
, 2023 We introduce a new diffusion-based approach for shape completion on 3D range scans. Compared with prior deterministic and probabilistic methods, we strike a balance between realism, multi-modality, and high fidelity.

Completion of occluded shapes using symmetry [PDF]
Proceedings of IEEE Conference on Computer Vision and Pattern Recognition, 2002 Following the view that symmetry is a continuous feature, a continuous symmetry measure (CSM) is developed to evaluate symmetrics of shapes and objects. The symmetry measure is extended to evaluate the symmetry of occluded shapes. Using the symmetry measure, occluded shapes are reconstructed by locating the center of symmetry of the shape. >
