Query: The HAWKwood Database   We present a database consisting of wood pile images, which can be used as a
benchmark to evaluate the performance of wood pile detection and surveying
algorithms. We distinguish six database cate- gories which can be used for
different types of algorithms. Images of real and synthetic scenes are
provided, which consist of 7655 images divided into 354 data sets. Depending on
the category the data sets either include ground truth data or forestry
specific measurements with which algorithms may be compared.
