A method for detection of wood defects based on ANN was studied in this paper. Because the intensity of X-ray that crosses the object changes, defects in wood were detected by the difference of X-ray absorption parameter, then computer was used to process and analyze the image. On the basis of image processing of nondestructive testing and characteristic construction, mathematic model of defects was...
X-ray as a method of measurement was adopted to detect wood defects nondestructively. Due to the intensity of x-ray that crosses the object changes, defects in wood were detected by the difference of X-ray absorption parameter, and therefore it used computer to process and analyze the image. On the basis of image processing of nondestructive testing and characteristic construction, defects mathematic...
