Inside the National Museum of Brazil

Por dentro do Museu Nacional” is a Google Arts & Culture project that makes it possible to revisit the collection of the National Museum of Brazil before its fire of 2018.

A virtual guided tour presents 360° views of the main galleries of the Museum:

This room displays the oldest skeleton discovered in the Americas, popularly known as Luzia.

In other sections of the website you can explore geological and archeological works such as meteorites and pottery pieces:

Meteorite Bendego: the largest Brazilian meteorite and one of the largest in the world.
Vaso globular Marajoara: cerâmica brasileira de 3000 anos

 

 

 

 

 

 

A Computer Vision and ML approach to understand urban changes

By comparing 1.6 million pairs of photos taken seven years apart, researchers from MIT’s Collective Learning Group now used a new computer vision system to quantify the physical improvement or deterioration of neighborhoods in five American cities, in an attempt to identify factors that predict urban change.

A large positive Streetchange value is typically indicative of major new construction (top row). A large negative Streetchange value is typically indicative of abandoned or demolished housing (bottom row).

The project is called Streetchange. An article introducing the article can be found here.
