Scots pine log end face images for developing identity matching methods for tree logs

For developing log identification methods, i.e., "face recognition" methods for log individuals, a total of 493 unique Scots pine logs were photographed to create this data set of 4930 log end face images.

The photography was completed in two sessions, each lasting one working day. In the first session, each log was photographed from five different perspectives: directly head-on, plus four other imaging angles. In the second session, which took place five days later, the same photography procedure was repeated for each log.

The data is structured into directories as //.jpg, where is the uniquely identifying number for each individual log, imaging day is either 01 (meaning the first imaging session) or 02 (meaning the second imaging session), and angle index is an integer from 0 (the direct head-shot image) to 4, where indeces from 1 to 4 signify the other imaging angles besides the direct head-on perspective.
