In the similarity matrix above, the pixels of 512 photographs were analyzed. This was done by grouping pictures from similar events into distinct categories and then running a similarity matrix to see how the pixels of the different pixels corresponded. The blue pixels show a correlation of 0 while the red pixels show a correlation of 1. A similarity matrix is a matrix of scores which express the similarity between two data points.
