Abstract

In recent years, driven by new standards and brand image, product quality has become highly critical in the beverage industry. Product quality does not concern the beverage in and of itself only, but also the extrinsic aspects, particularly the presence of very small foreign bodies. Without reliable and affordable methods for detecting such foreign bodies in semiopaque bottles, many manufacturers still opt for human visual inspection on the production line. Optical advanced technological systems such as X-ray based systems started to be used but such technologies are expensive and intrusive. Also the visible optical domain offers an alternative and an advantageous solution. Thus a novel detection method based on two robust criteria such as kurtosis and connected components is proposed to give a further validation of the detection output. The method applies on static images acquired by a RGB camera and the experimental results show its effectiveness in detecting random foreign objects regardless their size or their transparency in various semi opaque bottles.
