Plastic Garbage Imges Database – GaDaBa

The main idea of this website was creation of a plastic waste/garbage images database of objects constituting the typical contents of municipal waste. These groups of waste using methods of Computer Vision can be automatically selected on the sorting lines businesses for waste disposal. Digital waste images should reflect the specific conditions of the places where real objects will be located. Thus, every item placed in this database is presented in different lighting conditions and in a different position in relation to the image recorder, different degrees of deformation, purity and in a different environment. The images created in the collection were divided into groups depending on the type of material from which individual objects were made. Seven groups of materials were adopted for international designations - Fig. 1.
