Fast Hough Transform on GPUs: Exploration of Algorithm Trade-Offs

open access: yes, 2011
The Hough transform is a commonly used algorithm to detect lines and other features in images. It is robust to noise and occlusion, but has a large computational cost. This paper introduces two new implementations of the Hough transform for lines on a GPU.

Variation in Climate Shapes Seedling Recruitment Along Resource Gradients in a Northern Hardwood Forest

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...
