意大利面在干燥过程中会产生裂纹，降低了意大利面的商品价值和质量，因此在意大利面干燥过程中裂纹的检测非常重要。然而，源于麦麸的斑点的存在阻碍了裂缝的自动识别。在这项研究中，我们开发了一种简单的方法来检测裂纹诱导意大利面使用数码相机。通过对意大利面的透射光图像进行像素化处理，并根据由所有像素组成的直方图中的几何特征对图像进行分析，来区分裂纹和斑点。该方法是能够检测的裂纹中诱导的意大利面与粗糙的表面，这是通过青铜模具使用真空挤压成型，以及那些诱导的意大利面与光滑的表面，这是使用聚四氟乙烯模具制备。
Cracks are formed during the drying process of spaghetti production, which reduces its commercial value and quality; hence, it is very important to detect the cracks during the manufacturing process of dried spaghetti. However, the presence of mottles, originating from wheat bran, hinders automatic identification of cracks. In this study, we developed a simple method to detect the cracks induced in spaghetti using a digital camera. The cracks and mottles were distinguished by pixelating the transmission light image of the spaghetti and analyzing the image based on the geometric characteristics in the histogram consisting of all the pixels. The method was able to detect the cracks induced in the spaghetti with a rough surface, which was prepared via a bronze die using vacuum extrusion molding, as well as those induced in the spaghetti with a smooth surface, which was prepared using a Teflon die.
