Marked point processes for crowd counting

W Ge, RT Collins - 2009 IEEE Conference on Computer Vision …, 2009 - ieeexplore.ieee.org
A Bayesian marked point process (MPP) model is developed to detect and count people in
crowded scenes. The model couples a spatial stochastic process governing number and …

People watching: Human actions as a cue for single view geometry

DF Fouhey, V Delaitre, A Gupta, AA Efros… - Computer Vision–ECCV …, 2012 - Springer
We present an approach which exploits the coupling between human actions and scene
geometry. We investigate the use of human pose as a cue for single-view 3D scene …

Human height estimation by color deep learning and depth 3D conversion

D Lee, J Kim, SC Jeong, S Kwon - Applied Sciences, 2020 - mdpi.com
In this study, an estimation method for human height is proposed using color and depth
information. Color images are used for deep learning by mask R-CNN to detect a human …

Information-theoretic active scene exploration

E Sommerlade, I Reid - 2008 IEEE Conference on Computer …, 2008 - ieeexplore.ieee.org
Studies support the need for high resolution imagery to identify persons in surveillance
videos. However, the use of telephoto lenses sacrifices a wider field of view and thereby …

Depth and geometry from a single 2d image using triangulation

Y Salih, AS Malik - 2012 IEEE International Conference on …, 2012 - ieeexplore.ieee.org
We present a novel method for computing depth of field and geometry from a single 2D
image. This technique, unlike the existing ones measures the absolute depth of field and …
