Providing a strength related factor of wood material

摘要

The invention allows providing strength related factor of wood material that is more accurate than prior art solutions, yet at the same time more cost-effective and faster to produce and use. At least one digital image of at least a portion of wood material is obtained. A data size indication of at least a region of the obtained and compressed at least one digital image is generated. A strength related factor of the at least the portion of the wood material is determined based on the generated data size indication, the strength related factor correlating inversely with the data size indication.
