An image coder for the presentation of products with multiple color choices

E-commerce websites rely heavily on JPEG images for product presentation. We describe a new coding scheme and file format that is tailored to the presentation of single-color products with multiple color choices: Instead of using multiple files of the same product at different colors, the new file format allows the transmission of all color choices in one file. On the decoder side images of the same product at different colors can be conveniently recovered from the same file. We demonstrate that file size reductions above 90% are achievable, with little quality degradation.
