About Colourphon

A response to the enquiry "I borrowed a book last week; it was pink"

[edit]

Proposed feature set

API returns colour information for a given image.

  • Image can be specified using URL,
  • Image can be submitted as a FILE
  • Book jacket image lookup can be performed for an ISBN

Currently the foundation of the API is being used to return the GUI web interface. This exists for testing/exposure purposes. The API will involve calls to api.colourphon.co.uk, and will reuse the classes already created for the GUI/

Analysis

  • Mode of whole image - top 10000 colours, whittled down to a result set having varying count.
  • Centre weighted Mode of regions (cells) - top 1 colour in each cell. Cell given weighting according to position in image (0 is centre). Results ranked by weighting
[edit]

Use cases

  • Harvested data could be used to add extra facets to an image search
  • Searching for images based on colour placement.
  • Harvested images could be used to provide jacket image enrichments for known works, where the copyright of the image could not be resolved.
