电子散斑干涉条纹的计算机自动处理

电子散斑干涉条纹的噪声较强,一些常用的图像去噪、二值化、细化等算法对散斑干涉条纹的处理都存在一定的不足.针对散斑条纹的灰度值具有由两边向中间逐渐增强的特点,提出了一种新的计算机自动处理算法.该方法首先对干涉条纹进行巴特沃思滤波去噪、二值化,然后对其应用Hilditch细化计算机,实验结果表明此算法能较好地对一幅散斑干涉条纹图像进行细化.

Computer Automatic Processing for Electronic Speckle Image

The electronic speckle pattern interferometry has strong noises, some common methods such as filtering, binariza tion, thinning, etc, have deficiencies for image processing. Based on the characteristics that the gray values of speckle image are weakening from both sides to the middle gradually, a new algorithm for speckle image processing is proposed. The theoretic analysis and the experimental results prove that the interference fringes can be thinned effectively using this algorithm.
