The sawmilling industry stores and measures logs in bark in order to maximize efficiency, quality conservation and preservation. However, billing is based on the diameter under bark, which it is necessary to estimate based on manual or automatic bark

This paper summarises the comparison between log properties and resulting structural timber properties. The establishment of these relationships is a first step to place the grading as early as possible in the production process, if possible directly

Prediction of strength is an important aspect in machine strength grading of timber. This property is strongly influenced by grain direction: Deviations from the main direction can cause a dramatic loss of strength. Therefore, an essential demand of

The origin of the raw material is a key aspect for strength grading of timber. Large grading areas are favored by the sawmilling industry as they require less effort in handling and documentation during the production process. However, large growth a

The possibility for pre-grading of logs throughout the year has been evaluated based on dynamic modulus of elasticity (MOEdyn or simplified E dyn) by means of frequency-based nondestructive testing (NDTfreq). The challenge is that E dyn is variable i

This paper deals with pattern recognition based on colour and texture. The aim is to detect areas of bark and wood on images of spruce logs taken in the industrial environment of a sawmill. Bark is a material with high natural variability in texture

An important aspect in machine strength grading of timber is the direction of the grain and deviations from the main axis, which can cause a dramatic loss of strength. Therefore, an essential requirement of the wood industry is to find the direction
