Although this is a new minor version release it is fully compatible with former versions.
The Keyword Suggester is a semi-automatic image tagging system that can be applied to external image URL or to internal image IDs. The suggestions are calculated based on the keywords of indexed images that are visually similar to the input image.
It enables you to create keyword suggestions and keeps your keywords and categories for new images in the same wording style.
External image caching
When doing searches or keyword suggestions with external images, the image is downloaded and a feature is calculated on the fly. To speed up the process pixolution flow now supports caching of calculated image descriptors for URLs that have been used by the Keyword Suggester or within query by URL queries. This way multiple downloads of the same images can be avoided. The cache is fully configurable.
