Color conversion of book cover images to reflect reader impressions

摘要

The image on a digital book cover gives potential buyers not only an impression of the book's contents but also serves as an aid when searching and browsing before and after buying the book. We have developed a method for revising book cover images to reflect readers' impressions. It uses a database of the correspondence between adjectives and colors as extracted from book reviews. This correspondence is used to revise the colors in the original book cover image. Evaluation was done by having 20 participants read 5 target books and give their impressions of the book cover images. The results revealed that the revised images better reflected the reader impressions than the original images.
