World’s most detailed wide field space photo…..

…. has now been created! This was a great project over at the BBCs StarGazing Live 2015 getting the public to submit photos of Orion to create it. The clever bit is combining the photos together which, from the description, looks to use image matching algorithms that my PhD student James O’Connor is utilising in his research. It first matches the image to a known constellation to calculate the area of the sky it covers - if appropriate its accepted for processing, along with every other image of the same region. With the end of submissions, these are then all matched against one another, overlaid and combined together. This is, again, an image matching process although I’d be interested to know what they did for the combination.

A great example of remote sensing, citizen science and the way image processing cross-fertilises across disciplines.
