Semi-supervised wide-angle portraits correction by multi-scale transformer
We propose a semi-supervised network for wide-angle portraits correction. Wide-angle
images often suffer from skew and distortion affected by perspective distortion, especially …

Semi-supervised coupled thin-plate spline model for rotation correction and beyond
Thin-plate spline (TPS) is a principal warp that allows for representing elastic, nonlinear
transformation with control point motions. With the increase of control points, the warp …

Snap angle prediction for 360 panoramas
Abstract 360 panoramas are a rich medium, yet notoriously difficult to visualize in the 2D
image plane. We explore how intelligent rotations of a spherical image may enable content …

Does vergence affect perceived size?
P Linton - Vision, 2021 - mdpi.com
Since Kepler (1604) and Descartes (1637), it has been suggested that 'vergence'(the
angular rotation of the eyes) plays a key role in size constancy. However, this has never …
