Laplacian Meshes for Monocular 3D Shape Recovery [PDF]
, 2012 We show that by extending the Laplacian formalism, which was first introduced in the Graphics community to regularize 3D meshes, we can turn the monocular 3D shape reconstruction of a deformable surface given correspondences with a reference image into a well-posed problem. Furthermore, this does not require any training data and eliminates the need to

Complex 3D Shape Recovery Using a Dual-Space Approach [PDF]
2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2005 This paper presents a novel method for reconstructing complex 3D objects with unknown topology using silhouettes extracted from image sequences. This method exploits the duality principle governing surface points and their corresponding tangent planes, and enables a direct estimation of points on the contour generators. A major problem in other related

Complex 3D shape recovery using hybrid geometric shape features in a hierarchical shape segmentation approach [PDF]
2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009 We present a novel and reliable approach for complex object acquisition and surface registration using hybrid geometric shape features in a hierarchical 3D shape approximation and segmentation approach. First, instead of relying on one type of scanned data, we propose to use hybrid data provided that it can support both global and local geometric shape

Mine-used pick wear measurement system based on shape from focus
Gong-kuang zidonghua, 2019 For problems of complicated process, low accuracy and high cost in existing pick wear measurement methods, a mine-used pick wear measurement system based on shape from focus was designed. The collected sequence images of cone on top of pick are processed

A Fast Shape-from-Focus-Based Surface Topography Measurement Method
Sensors, 2021 Shape from focus is an accurate, but relatively time-consuming, 3D profilometry technique (compared to e.g., laser triangulation or fringe projection). This is the case because a large amount of data that needs to be captured and processed to obtain 3D ...

Autocalibration with the Minimum Number of Cameras with Known Pixel Shape [PDF]
, 2014 In 3D reconstruction, the recovery of the calibration parameters of the cameras is paramount since it provides metric information about the observed scene, e.g., measures of angles and ratios of distances.

Focus Measurement in Color Space for Shape From Focus Systems
IEEE Access, 2021 Shape from Focus (SFF) has been studied extensively in computer vision for 3D shape and depth recovery. The first stage in SFF methods is to compute the focus value of every pixel by converting the colored images into gray scale and then apply the focus ...
