ImageMG

Description

ImageMG: The Image Dataset with Religious Buildings from the State of Minas Gerais (Brazil) for Cultural Heritage Classification using Deep Learning. The ImageMG contains 6,449 images collected from 94 religious buildings in 19 historic towns from state of Minas Gerais (MG): Carmo do Cajuru, Conceição do Pará, Datas, Diamantina, Itabirito, Itapecerica, Itaúna, Lagoa Dourada, Mariana, Mateus Leme, Oliveira, Onça do Pitangui, Ouro Branco, Ouro Preto, Pitangui, São Brás do Suaçuí, São João del-Rei, Serro, and Tiradentes. The classes addressed (fronton, church, window, door, and tower) for the deep learning detection process reflect the characteristics of religious monuments built in Brazil during the 18th and 19th centuries in the Baroque and Rococo styles. ImageMG represents an advancement compared to another recently presented dataset: $ ImageOP - https://data.mendeley.com/datasets/hdz96zts8j/1 ImageOP contains 1,613 images of 32 religious buildings from the Historic Town of Ouro Preto, considered the first Brazilian World Heritage Site by UNESCO. In this sense, ImageMG incorporates the images from ImageOP by adding 62 more buildings, 18 historic cities, and 5,036 images. The ImageMG dataset was divided into three image subsets according to the experimental stage evaluated (train, validation, and test). # In the training stage (ImageMG-train), 4,344 images of 72 cultural heritage buildings from 15 historic towns were used. # Additionally, in the validation phase (ImageMG-val), 836 images from two important Brazilian historic cities, Mariana and Pitangui, were adopted. # Finally, for the test experiments, 1,269 images of 13 religious buildings were collected. It is noteworthy that in the test phase, two cities from the state of Minas Gerais, significant for Brazilian Baroque, were selected: Diamantina and Serro. The Historic Centre of the Town of Diamantina is a World Heritage Site recognized by UNESCO. Moreover, the historic town of Serro is a relevant Brazilian architectural complex listed by the National Institute of Historical and Artistic Heritage. (Instituto do Patrimônio Histórico e Artístico Nacional – IPHAN) since 1938.
