Lire web demo updated – two additional global features

The LIRE web demo now includes an RGB color histogram as well as the MPEG-7 edge histogram implementation. The color histogram works well for instance for line art, such as this query.The edge histogram works fine for clear, gloabl edge distributions like queries such as this one. However, it’s performing different from PHOG. An example for the difference is this PHOG query compared to the according edge histogram query. The image below shows both queries.

Web based LIRE demo now online

A new web based LIRE demo is online. Within this demo you are able to search in an index of 300.000 images from the MIRFLICKR data set. Currently online queries from within the index are allowed, so no custom query images can be uploaded. The backend is plain LIRE, so there’s no search server and alike, and it’s the current SVN version. Search is done based on hashing, so the results are approximate, but they are immediately there. Also it’s just a selection of global features, but it’s enough to get the idea. The image below shows the result of two example searches.

Nice but out of reach: popular multimedia platforms

Netflix was reported last year to be the source of nearly 30% of the North American internet backbone traffic. Well that’s impressive, but that’s something that many non North Americans can’t understand … and there’s a simple reason for that: the service is not available in many countries. Several well known and well received services are restricted to a range of IP adresses that are considered in a geographic location where users have access to this services. Here is a small but still interesting list of services that have obviously impact on the usage of the internet, but cannot be accessed in many European countries.

  • Netflix – major video streaming service (subscription based)
  • Pandora – music streaming service / adaptive online radio (ad supported)
  • Hulu – major video streaming service of already aired TV content (ad supported)
  • Vevo – music video streaming service (ad supported). Most of the music videos on Vevo are available on YouTube for Austrians, but most of these music videos are not accessible of Germans.
  • NBC – video streaming service of already aired NBC TV content.
  • ABC – video streaming service of already aired ABC TV content.

 

Micro Loans with Kiva

Yesterday Markus Strohmaier pointed me towards Kiva, a microloan page. I think this is a great way to help people!

Choose an Entrepreneur, Lend, Get Repaid

The below diagram shows briefly how money gets from you to an entrepreneur, and back.

1) Lenders like you browse profiles of entrepreneurs in need, and choose someone to lend to. When they lend, using PayPal or their credit cards, Kiva collects the funds and then passes them along to one of our microfinance partners worldwide.

2) Kiva’s microfinance partners distribute the loan funds to the selected entrepreneur. Often, our partners also provide training and other assistance to maximize the entrepreneur’s chances of success.

3) Over time, the entrepreneur repays their loan. Repayment and other updates are posted on Kiva and emailed to lenders who wish to receive them.

4) When lenders get their money back, they can re-lend to someone else in need, donate their funds to Kiva (to cover operational expenses), or withdraw their funds.
