Visual Inspection Method of Ceramic Bottle Surface Defects Based on Niblack Optimization

Visual Inspection for Fired Ceramic Tile’s Surface Defects using Wavelet Analysis

This paper deals with the visual inspection of ceramic’s tiles surfaces for the purpose of detecting flaws using a wavelet approach. Surface defects in the ceramic tiles are viewed as in-homogeneities in regularity and orientation fields. To improve the homogeneity of batches received by final users and to detect manufacturing defaults, most production lines for ceramic tiles must integrate a v...

Wood Surface Inspection System Based on Generic Visual Features

Detection of surface defects on ceramic tiles based on morphological techniques

Ceramic tiles have become very popular and are used in the flooring of offices and shopping malls. As testing the quality of tiles manually in a highly polluted environment in the manufacturing industry is a laborintensive and time consuming process, analysis is carried out on the tile images. This paper discusses an automated system to detect the defects on the surface of ceramic tiles based o...

Real-time Aspects of SOM-based Visual Surface Inspection

We have developed a self-organizing map (SOM) -based approach for training and classification in visual surface inspection applications. The approach combines the advantages of non-supervised and supervised training and offers an intuitive visual user interface. The training is less sensitive to human errors, since labeling of large amounts of individual training samples is not necessary. In th...

Automatic Image Inspection Method for Detection of Superficial Defects on Circular Top Sides of Cylindrical Ceramic Rods

In the last decades, new computer vision technologies and image processing techniques have been very important in the improvement and automation of manual processes in many technical areas, e.g., in the semiconductor industry. In this paper, we propose an automation method for a currently deployed manual inspection procedure by using image processing techniques, in order to detect and measure s...
