Real-time stereo matching on CUDA using Fourier descriptors and dynamic programming

Computational Visual Media, 2019
Computation of stereoscopic depth and disparity map extraction are dynamic research topics. A large variety of algorithms has been developed, among which we cite feature matching, moment extraction, and image representation using descriptors to determine

On Generating Synthetic Datasets for Photometric Stereo Applications

Computers
The mathematical model for photometric stereo makes several restricting assumptions, which are often not fulfilled in real-life applications. Specifically, an object surface does not always satisfies Lambert’s cosine law, leading to reflection issues ...

(R)-evolution in the implementation of photometric stereo – Application to archaeology [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
There are two main families of photographic 3D reconstruction methods. On the one hand, so-called geometric methods (photogrammetry), which use images of the scene taken from different viewpoints, are based on the principle of triangulation.

Disparity estimation of stereo-endoscopic images using deep generative network

ICT Express
A 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

Latent Code Predictor for Accelerating Disparity Estimation in Stereo-Endoscopic Surface Reconstruction

Sensors
Disparity estimation from stereo-endoscopic images is critical for 3D reconstruction in minimally invasive surgery (MIS). However, surgical environments have inherent interference factors including soft tissue deformation, motion blur, and photometric ...
