Abstract

Scots pine (Pinus silvestris) logs and 106 Norway spruce (Picea abies) logs. Two of the models were the classical 3-parametric circle model and the 5-parametric ellipse model. These models were compared to the third model, the Fourier coefficient model, which had a variable number of parameters. By increasing the number of parameters in the Fourier coefficient model, this model fits the true shape perfectly. With the same number of parameters the Fourier model performed approximately as good as the two other models. To get a substantial improvement over the ellipse model the number of parameters had to be raised dramatically.
