| Description: |
The automatic detection of tree-ring boundaries and other anatomical features using image analysis has progressed substantially over the past decade with advances in machine learning and imagery technology, as well as increasing demands from the dendrochronology community. This paper presents a publicly available database of 64 scanned images of transverse sections of commercially grown Pinus taeda trees from northern Uruguay, ranging from 17 to 24 years old. The collection contains several challenging features for automatic ring detection, including illumination and surface preparation variation, fungal infection (blue stains), knot formation, missing cortex or interruptions in outer rings, and radial cracking. This dataset can be used to develop and test automatic tree ring detection algorithms. The dataset was used to develop the Cross-Section Tree-Ring Detection (CS-TRD) method. Dataset Article published in ANFS. ; The UruDendro data set is organized in several files, containing the images and the marks as described in below table.

Additionally, images with a printed scale bar are stored in images_scale_bar.zip where the size of the scale bar is of 50mm and the relation pixel/millimiter per image ... |
