Extração de características de padrões speckle para sensores a fibra óptica

Abstract: This work presents a classification system, based on texture features extracted from the speckle pattern, to determine 3 different regions in which an optical fiber is mechanically perturbed. Two different descriptors are used: the Local Binary Pattern (LBP) and the Gray Level Co-occurrence Matrix (GLCM) for extracting characteristics, which are applied to an Artificial Neural Network. Accuracy was analyzed for seven different characteristic amounts. The results show that, for an optical fiber of 50 µm automat… Show more
