Color Tool

An analysis and synthetic representation experiment about color relations and proportions in images

An online tool to analyse color proportions and relations in raster images:

  • Web-based, but the analysis is computed locally by JavaScript code.
  • taking into account color perception by using colorspaces as YUV or CIE Luv*
  • Using a pseudo-cartographical representation based on the color circle and proportionnal colored circles, in 2D or 3D.

Operating principles

  • A sampling of the image pixels is done, following the sampling rate provided.
  • A K-means segmentation is calculated, on means or medians of the color-corrected values.
  • A cartographic representation is drawn, in 2D or 3D.
  • Results can be exported as images (png or svg) or as values (csv text file)
