SPUD: Simultaneous phase unwrapping and denoising algorithm for phase imaging
(2020-05-01)
Recent methods for phase unwrapping in the presence of noise include denoising algorithms to filter out noise as a preprocessing stage. However, including a denoising stage increases the overall computational complexity ...
Hybrid calibration method for improving 3D measurement accuracy of structured light systems
(2020-08-21)
In structured-light systems, the lens distortions of the camera and the projector reduce the measurement accuracy when calibrated as a standard stereo-vision system. The conventional compensation via distortion coefficients ...
A low-cost multi-modal medical imaging system with fringe projection profilometry and 3D freehand ultrasound
(2020-01-03)
The growing need to perform surgical procedures, monitoring, and intervention of greater precision have led to the development of multimodal medical imaging systems. Multimodal images are a strategy to overcome the limitations ...
Automated corneal endothelium image segmentation in the presence of cornea guttata via convolutional neural networks
(2020-08)
Automated cell counting in in-vivo specular microscopy images is challenging, especially in situations where single-cell segmentation methods fail due to pathological conditions. This work aims to obtain reliable cell ...
Toward the generation of reproducible synthetic surface data in optical metrology
(2020-05-19)
The implementation and generation of synthetic data for testing algorithms in optical metrology are often difficult to reproduce. In this work, we propose a framework for the generation of reproducible synthetic surface ...
