PUGTIFs: Passively User-Generated Thermal Invariant Features

IEEE Access, 2019
Feature detection is a vital aspect of computer vision applications, but adverse environments, distance and illumination can affect the quality and repeatability of features or even prevent their identification. Invariance to these constraints would make

Twelve years of fin whale song evolution in the central North Pacific

Frontiers in Marine Science
Fin whale song consists of low frequency notes arranged in regular, repeating patterns of note type pairings and inter-note intervals (INIs). In the central North Pacific, fin whales use two downswept note types (A and B notes) with both singlet and ...
