Finding repeated images - part 1 - Vector Similarity Measures

Series Part 1, Part 2, Part 3

I’ve been playing around with spatial matching on clker.com . My goal was to figure out whether an image being submitted already exists or not, and to do that very fast. Titles, tags and all information in the image can change, so basically they are useless when it comes to know whether an image is repeated with high confidence. What is really needed is a set of features, that can be extracted fast enough and stored in the database, and indexed in a practically searchable manner.

Better meta data and better tagging

Tuesday, November 27th, 2007

Many things happened over the thanksgiving weekend. First there’s a lot of work done in reading the svg metadata, parsing and using it. Now, all the tags inside the svg files are used as tags for the images. Also, the title of the clipart page first is obtained from the svg metadata. If the svg metadata did not have a title, then we make up a title from the original svg filename.

Over the search bar a bread crumb is now visible that shows where the user is, and how he is opening the tags and relative tags. Under the search bar, the most prominent tags are shown. This helps the user to fine tune his search.

Adding picture to your wordpress weblog

Tuesday, November 20th, 2007

Human beings are visual creatures. Pictures and eye sight is the second important way by which humans learn after hearing. Adding pictures related to your post will help visitors get your point. Exactly like adding pictures in a presentation, which help people understand the description made by the presenter.

Adding pictures to your weblog post will also help attract attention to your article, and increase the time your visitors stay. Pictures breaks the boring lengthy text of an article and gives the reader a break in the middle.

An important factor is then how easy is it to a) find a picture ad b) add it to your weblog?

Clker.com offers a huge collection of high quality cliparts. All cliparts are tagged with relevant words making it very easy to search and find the exact picture you’re looking for. You can directly copy the HTML code and paste it in your weblog’s page. All pictures can be easily embedded in any HTML source.

By default, all pictures are floated to the left making the text wrap around it without wasting your weblog space. You can manually remove the float and allow the picture to occupy a full horizontal area as shown above.
