Results: semantic expressions and associated colors
Using freely available Flickr images our algorithm estimates a color value for an arbitrary semantic expression. The top five rows of the figure below show results for color names, the bottom two rows for other semantic expressions related to color.
Other color estimates for different shades of the three basic memory colors: vegetation, skin and sky.
Method in brief
Using Flickr’s API we acquire for each semantic expression two hundred associated images (i.e. images that have been annotated with that expression). We then carry out a statistical test that assesses for each color bin whether the presence of a keyword makes it likely to have a significantly higher (lower) bin count. This is reflected by a positive (negative) standardized significance value as sgown in the figure below.
