Pixolu is a semantic image search tool that can be found online at Pixolu.de.
What this search tool does is to find images that are tailor-made for you, based on the search criteria that you specify beforehand.
The mechanics of the site are quite straightforward. Basically, what you have to do is provide a keyword of keywords for the engine to take into account. As it was mentioned above, this is a semantic search. This means that the results that will come up are better-suited than the ones you could get from using a “traditional” search engine. After keying in the corresponding words (“Astronaut on the moon”, for instance) you are presented with preliminary image results. Then you have to pre-select the pictures that interest you from that lot. After this is done, the system carries out a next search taking into account the pictures you have preselected.
It is also possible to specify the number of results to be yielded using a slide bar located underneath the search box. You can also choose the search channels by clicking on the “Flickr”, “Google” and “Yahoo” boxes which are displayed.
