Cork is a natural material that is used to seal wine bottles due to its reliability and its chemical and mechanical properties. A colour image acquisition system is able to differentiate some cork defects. The developed and implemented system acquires images using a colour linear CCD camera, transmits that image through a fast acquisition card and processes that image to extract quantitative elements. This system can analyse and distinguish defects present on the surface of a cork stopper: the size, form and position of the defects are analysed.engImage processingQuality controljournal article
