Single-View 3D Reconstruction of Animals
Humans have a remarkable ability to infer the 3D shape of objects from just a single image. Even for complex and non-rigid objects like people and animals, from just a single picture we can say much about its 3D shape, configuration and even the viewpoint that the photo was taken from. Today, the …

Learning Monocular Cues in 3D Reconstruction
3D reconstruction is a fundamental problem in computer vision. While a wide range of methods has been proposed within the community, most of them have fixed input and output modalities, limiting their usefulness. In an attempt to build bridges between different 3D reconstruction methods, we focus …

3D Reconstruction of Building Interiors Using Point Clouds
… building interiors, known as indoor building reconstruction, is gaining increasing attention because of its widespread applications. With the development of sensors to acquire high-quality point clouds, a new modeling scheme called scan-to-BIM (building information modeling) emerged. However, …

Semantic Segmentation and 3D Reconstruction of Concrete Cracks
… accurate parameter estimation. Finally, two 3D reconstruction methods are proposed, one of which is based on detecting the dominant structural plane surrounding the crack, while the second method focuses on matching the crack pixels across two images. As a result, a 3D model of cracks is …

3D reconstruction and camera calibration from 2D images
A 3D reconstruction technique from stereo images is presented that needs minimal intervention from the user. The reconstruction problem consists of three steps, each of which is equivalent to the estimation of a specific geometry group. The first step is the estimation of the epipolar geometry that …

3D reconstruction of human body via machine learning
Three-dimensional (3D) reconstruction and modeling of the human body and garments from images is a central open problem in computer vision, yet remains a challenge using machine learning techniques. We proposed a framework to generate the realistic 3D human from a single RGB image via machine …

3D reconstruction of cuboid-shaped objects from labeled images
… thesis, my goal is to determine a rectangular 3D cuboid that outlines the boundaries of a cuboid-shaped object shown in an image. The position of the corners of each cuboid are manually labeled, or annotated, in a 2D color image. Given the color image, the labels, and a 2D depth image of the …

Combining recognition and geometry for data-driven 3D reconstruction
Today's multi-view 3D reconstruction techniques rely almost exclusively on depth cues that come from multiple view geometry. While these cues can be used to produce highly accurate reconstructions, the resulting point clouds are often noisy and incomplete. Due to these issues, it may also be …
