Shape and colour recognition of dishes for the purpose of customer service process automation in a self-service canteen
Tomasz Kryjak, Damian Król · Annals of Computer Science and Information Systems · 2015
In the article a vision system for shape and colour recognition of dishes (plates, bowls, mugs), which can be used to automate the process of customer service in a self-service canteen is described.In consists of three basic components: object segmentation using so-called background model subtraction, shape recognition using geometric invariant moments and SVM classifier, as well as colour recognition using a Gaussian model.In addition, recognition in case of close or abut objects using a distance transform like approach is presented.The solution was evaluated on a dedicated test stand with controlled LED lightning.A 98% accuracy was obtained on over 100 test images, which indicates that the solution could be used in business practise.
