Taxonomic identification of Amazonian tree crowns from aerial photography

Whale Detection & Identification from Aerial Photography

The North Atlantic Right Whale is a critically endangered species of baleen whale, with an estimated fewer than 500 individuals living in our oceans [1, 2]. In the interests of science and conservation, it is necessary to track and monitor these animals. Currently, only a few experienced researchers are able to identify and tag individual whales through the use of custom software and this proce...

Automated Model Creation from Aerial Photography

Creating a model, instead of just making measurements, is a common task in photogrammetry today. Methods can vary depending on the requirements, data availability, and type of scenery. The amount of user input is one major differentiating factor. The methods discussed in this paper align closely with a typical workflow for urban mapping from aerial photographs.

Automated Georeferencing of Historic Aerial Photography

Historic aerial photos are typically very popular, sought-after collections in library archives. Their ability to be used in GIS is limited, however, by the laborious and painstaking georeferencing process. A method is presented for automating the georeferencing of historic aerial photography. In this method, the Harris Corner Detector is used to detect corner points in already-georeferenced an...

Detection of Tree Crowns Based on Reclassification Using Aerial Images and Lidar Data

Tree detection using aerial sensors in early decades was focused by many researchers in different fields including Remote Sensing and Photogrammetry. This paper is intended to detect trees in complex city areas using aerial imagery and laser scanning data. Our methodology is a hierarchal unsupervised method consists of some primitive operations. This method could be divided into three sections,...
