Liebl. and Quercus robur L.) logs: the Biomtrace database 2024-05-01T00:00:00 The Biomtrace database contains 33390 RGB images of the bottom cross-section of 5135 French oak logs. Each log was photographed four or five times at different camera orientations during an initial shot. In most cases, additional photos were taken at least three weeks after the first shot. The cross-sections were segmented on all the images using the PointRend convolutional neural network. Spatial calibration was carried out by a specific algorithm using a checkerboard pattern present in each image. The database was created to develop and test methods for the biometric traceability of oak logs by image analysis of their cross-section.
