Characterization of color cross-talk of CCD detectors and its influence in multispectral quantitative phase imaging [PDF]
, 2018 Multi-spectral quantitative phase imaging (QPI) is an emerging imaging modality for wavelength dependent studies of several biological and industrial specimens. Simultaneous multi-spectral QPI is generally performed with color CCD cameras. However, color

Robust odometry estimation for RGB-D cameras [PDF]
2013 IEEE International Conference on Robotics and Automation, 2013 The goal of our work is to provide a fast and accurate method to estimate the camera motion from RGB-D images. Our approach registers two consecutive RGB-D frames directly upon each other by minimizing the photometric error. We estimate the camera motion using non-linear minimization in combination with a coarse-to-fine scheme.
