Emir Demo Screen ShotI just uploaded the new Emir demo video. Now the video features the shiny JGoodies Look and not the crappy original Java style any more. To play it you will need a Flash player and this link, or just click it in the menu on the right hand side.

Continue reading uses LIRE for Image Search

CorvusAlbusRecently a friend of mine – Roman – put up his all fresh and newly created personal information portal CorvusAlbus featuring Web 2.0 client side encryption, photo and text blogs, excessive use of style sheets and javascript and …. Tada: similarity search for images. He included LIRE to allow users to search for similar photos.

corvusalbus02.pngWhen you browse through the photos (as shown in above screenshot) you will find a small find similar link on the topo right of the browser window.

Only FireFox, Opera and Konqueror are supported.
