CZU normal cropped dataset

The CZU dataset collected from the Czech University of Life Sciences, Prague (CZU) campus in 2022, includes 386 images of European beech (Fagus sylvatica L.), Large-leaved linden (Tilia platyphyllos), Norway Maple (Acer platanoides), and Scots pine (Pinus sylvaltica L.). The dataset comprises multiple angles of tree stems, with at least ten photographs taken per tree to capture the bark structure and patterns. In this dataset we removed the anomaly region from the images, kept the rest of the image in the original form, and named these datasets normal cropped.
