Abstract

Abstract:

In order to evaluate the status of cracks in microwave-treated lumbers during the research of microwave wood functional modification. A method of evaluation the wood cracks based on the Matlab image processing was developed. It was applied to statistically analyze the cracks in microwave-treated lumbers. The method can be used to process pictures of wood cracks taken from scanner. The cracks can be outstanding from other areas after the steps of turning the RGB figures to gray figures, subtracting the background of the figure, adjusting the contrast gradient, thresholding the gray figure. Then write a procedure and run it in the Matlab software, the number, the length, the area and other statistical results of the cracks in the processed figure can be obtained.

Key words: Matlab, wood cracks, image processing, evaluation
