             abstract = "The ceramic industry has a highly automated production system. The 
                         quality control, however, is still performed by humans, which 
                         limits its speed and precision. This work proposes a complete 
                         verification system for ceramic tiles based on image processing 
                         and machine learning. The system has four steps: image 
                         acquisition, pre-processing, feature extraction and 
                         classification. The feature extraction step uses 
                         Segmentation-based Fractal Texture Analysis (SFTA). A Support 
                         Vector Machine is employed to classify the ceramic tiles. The 
                         system is implemented using OpenCV libraries. In total, 783 
                         ceramic tiles were used, being 80% for training and 20% to 
                         testing. The present work had reached the proposed objectives, 
                         both in processing time and accuracy, achieving 98.68% of 
                         detection rate.",
