For those of you interested in the poster I uploaded it here.

I also uploaded the presentation to slideshare.

• Major speed-up due to change and re-write of indexing strategies for local features
• Auto color correlation and color histogram features improved
• Re-ranking filter based on global features and LSA
• Parallel bag of visual words indexing and search supporting SURF and SIFT including incremental index updates (see also in the wiki)
• Added functionality to Lire Demo including support for new Lire features and a new result list view

Download and try:

• Source and binaries (or as tar.bz2)
• Lire Demo

• Auto Color Correlogram and Color Histogram features improved
• Re-ranking based on different features supported
• Enhanced results view
• Much faster indexing (parallel, use -server switch for your JVM)
• Much faster search (re-write of the searhc code in Lire)
• New developer menu for faster switching of search features
• Re-ranking of results based on latent semantic analysis

You can find the updated Lire Demo along with a windows launcher here, Mac and Linux users please run it using “java -jar … ” or double click (if your windows manager supports actions like that

• Download Liredemo v0.9 alpha 2

The source is — of course — GPL and available in the SVN.

Actually I programmed a lot of spiders and grabbers before, so I knew that there is a lot of data available on Flickr But I was still searching for an easy way. Now here is my approach (using of course bash):

wget -q -O - http://api.flickr.com/services/feeds/photos_public.gne?format=atom | grep -o .............static.*m.jpg | wget -i -

Why should this work?

• The first wget command gets a list of recent photos as atom feed.
• The grep command gets out all the medium sized (suffix “m.jpeg”) pictures
• The lot of dots and the static are just a nice trick to get the right ones, the real image content.
• Finally the second wget downloads the images from the server.

Issuing this command one should get ~ 25 photos in one go. Using a bash loop or a cronjob you can get of course a lot more in an unattended way

Recently Savvas Chatzichristofis released a Facebook app based on his tool img(Rummager) to retrieve the photos of Facebook contacts based on image content. The tool – called img(Finder) – allows to connect to a Facebook account and creates an index based on the CEDD and FCTH image features. img(Finder) indexes the images of all Facebook friends. Querying the index is done by sketch (painting tool is included) or by sample image. Best of all: The tool is open source

Title: Multimedia Semantics – The Role of Metadata
Editors: M. Granitzer, M. Lux & M. Spaniol
Pages: ~260
ISBN: 978-3-540-77472-3

The web page at Springer is here. I’ll blog more about the book as soon as it is published.

• It has a really cool GUI Editor.
• The editor doesn’t suck any more (some refactoring, code completion and templates, …).
• It supports many common tools (Ant, SVN, JUnit, ..).
• It’s the alternative to Eclipse.

I found one bug thing though: I created a class Tile with two members: One of the class Rectangle2D.Double and one of the class Point2D.Double. When using the automatic Getter and Setter code generation the return values for the Getter for the point were just Double while the Getter for the rectangle returned java.awt.geom.Rectangle2D.Double. That’s not really an issue, I know, but not the optimal way of programming either. At least I was not satisfied and edited the source afterwards
