| Abstract: | Ihe computer image processing technology was used to accomplish the feature extraction of defect images on wood surface. By calculation of gray values of defects. three feature data which are useful to identify the defects have been achieved. The experiment indicates that this way is effective to the automation recognition of the defects on wood surface. |
