SPEC: Seeing people in the wild with an estimated camera

M Kocabas, CHP Huang, J Tesch… - Proceedings of the …, 2021 - openaccess.thecvf.com
Due to the lack of camera parameter information for in-the-wild images, existing 3D human
pose and shape (HPS) estimation methods make several simplifying assumptions: weak …

Neural-guided RANSAC: Learning where to sample model hypotheses

E Brachmann, C Rother - Proceedings of the IEEE/CVF …, 2019 - openaccess.thecvf.com
Abstract We present Neural-Guided RANSAC (NG-RANSAC), an extension to the classic
RANSAC algorithm from robust optimization. NG-RANSAC uses prior information to improve …

Soft labels for ordinal regression

R Diaz, A Marathe - … of the IEEE/CVF conference on …, 2019 - openaccess.thecvf.com
Ordinal regression attempts to solve classification problems in which categories are not
independent, but rather follow a natural order. It is crucial to classify each class correctly …

Perspective fields for single image camera calibration

L **, J Zhang, Y Hold-Geoffroy… - Proceedings of the …, 2023 - openaccess.thecvf.com

Deep hough-transform line priors

Y Lin, SL Pintea, JC Van Gemert - … , Glasgow, UK, August 23–28, 2020 …, 2020 - Springer
Classical work on line segment detection is knowledge-based; it uses carefully designed
geometric priors using either image gradients, pixel grou**s, or Hough transform variants …

Blind geometric distortion correction on images through deep learning

X Li, B Zhang, PV Sander… - Proceedings of the IEEE …, 2019 - openaccess.thecvf.com
We propose the first general framework to automatically correct different types of geometric

A perceptual measure for deep single image camera calibration

Y Hold-Geoffroy, K Sunkavalli… - Proceedings of the …, 2018 - openaccess.thecvf.com
Most current single image camera calibration methods rely on specific image features or
user input, and cannot be applied to natural images captured in uncontrolled settings. We …

Deep single image camera calibration with radial distortion

M Lopez, R Mari, P Gargallo, Y Kuang… - Proceedings of the …, 2019 - openaccess.thecvf.com
Single image calibration is the problem of predicting the camera parameters from one
image. This problem is of importance when dealing with images collected in uncontrolled …

A step towards understanding why classification helps regression

SL Pintea, Y Lin, J Dijkstra… - Proceedings of the …, 2023 - openaccess.thecvf.com
A number of computer vision deep regression approaches report improved results when
adding a classification loss to the regression loss. Here, we explore why this is useful in …
