Brazilian Coin Detection Dataset

This dataset is a collection of images and their respective labels containing examples of multiple Brazilian coins, the primary purpose is to support the development of Computer Vision techniques for automatic detection of such objects, i.e., localization and classification tasks. It contains coins of R$ 0.05, 0.10, 0.25, 0.50 and 1.00 in Brazilian currency from the 2nd family, as manufactured by Casa da Moeda (http://www.casadamoeda.gov.br) since 2010. The samples were collected with a mobile phone and contain multiple coins placed upon a flat white A4 sheet of paper. Labels were obtained from a group with several individuals from both sexes and detailed reviewed. Each label has a circular or polygon shape and denotes the corresponding value in cents of the coin it is related to. This dataset is an improvement from Brazilian Coins (available at https://www.kaggle.com/lgmoneda/br-coins) where location labels were created.
