Disparity estimation of stereo-endoscopic images using deep generative network
ICT ExpressA novel disparity estimation pipeline is proposed for 3D reconstruction of dynamic soft tissues in minimally invasive surgery (MIS), which uses a deep generative network to learn manifold distributions of reasonable disparity maps from past stereo images

Shape from photometric stereo and contours
, 2004 Full text is available to authenticated members of The University of Auckland only.We propose a method for 3D shape recovery based on the combination of the photometric stereo and the shape from contours method.

Picking Up an Object from a Pile of Objects
, 1983 This paper describes a hand-eye system we developed to perform the binpicking task. Two basic tools are employed: the photometric stereo method and the extended Gaussian image.

, 1998 The human brain seems to have the ability of inferring shape from the binocular fusion of some kinds of monocular images. Recently, we have observed that photometric stereo (PS) images, which are monocular images obtained under different illuminations,

OpticaIn fringe projection profilometry (FPP), a high spatial frequency of fringe typically indicates powerful error suppression capability; however, it complicates phase unwrapping, necessitating a greater number of patterns and thus compromising the real-time performance of scanning. In this letter, we report a fringe photometric stereo (FPS) to completely

3-D Stereo Using Photometric Ratios
, 2007 We present a novel robust methodology for corresponding a dense set of points on an object surface from photometric values, for 3-D stereo computation of depth.

A Combined Multi-View Stereo and Photometric Stereo Approach
, 2009 Two approaches to 3D-reconstruction from images, Multi-view Stereo and Photometric Stereo, are combined as a means of completing missing areas within the partly-complete reconstruction returned by the first approach.

Generalizable stereo depth estimation with masked image modelling
Healthcare Technology LettersGeneralizable and accurate stereo depth estimation is vital for 3D reconstruction, especially in surgery. Supervised learning methods obtain best performance however, limited ground truth data for surgical scenes limits generalizability.
