1. A method for detecting the quality of debarking at the surface of a wooden log, comprising the steps of: i) measuring a three-dimensional profile of at least a portion of the log surface to generate corresponding profile image data; ii) processing said profile image data to generate data indicative of the texture of said log surface; and iii) analyzing said texture data to generate resulting data on parameters related to the debarking quality of said log surface, said parameters including fiber loss and residual bark.
