SegamiSearch has been renamed to "Similage" (similar + image)

The new site can be accessed from

Whats new?
  • Face Detection : search images containing faces 
  • Improved similarity search algorithm
  • Multiple similarity  search options: Similar colors, similar features
  • Sketch and Find: sketch shapes and discover new images!
  • Search by prominent colors in an image
  • Gray-scale images: search only black and white images
  • Improved user interface
  • Larger image database
So, yes a whole lot of things changed, its a totally different image search engine!

To Errr Is Human: Search Engines Should Suggest Corrections was updated with a new "Spelling Correction" feature. When you submit a query to the search engine, it will analyze it and will suggest, what it considers to be a better and popular query. This is useful if you make mistakes, for example typing someone's name.

This feature is based on n-grams which are used by major search engines on the web and many natural language processing applications. I will post more details on the algorithm, and how it works soon.

Performance Upgrade - Image Thumbnails

Just updated with a performance upgrade. The format of thumbnail images are now JPEG instead of PNG. The images are more compressed and filesize is significantly reduced, thus the result pages load much faster.

Segami Revealed

Today is the launch of , Version Alpha.

Its called version alpha, since this is more of a technology demo, to demonstrate the technology capabilities of the search engine. The image index is small, and mostly has images from Univ of Southern California, where the project was originally developed. Currently crawling is underway to build a much bigger index of images.

This is an exciting moment, as for the first time in web search history we see a web image search engine with image similarity search feature. Even though the algorithm is still being refined, it shows the future to where we are headed, breaking the traditional "keyword only" search.

Play around with the search engine, have fun with it, and most importantly, provide me with feedbacks and suggestions.

"Segami Search" is an image search engine. I had to figure out a name which reflected that.

Naming websites is an art, these days, since most of the names are already registered. Some of the names were just registered, but no actual site existed.

No wonder, the current Web 2.0 companies, and search engines, seem to follow a trend of coming up with strange combination of letters, which had no meaning - but sounded catchy, which are purposely misspelled or from a non-english language.

I played around with a few words, their synonyms. After a lot of word combinations, came up with "Segami" which is "images" spelled backwards! And combined with "Search" was perfect as it reflected the core search paradigm, and sounded good.


Welcome to the official blog of, the world wide web image search engine. Currently the site is under development, the alpha version will be launched soon.

Segami Search started as a graduate project at University of Southern California. It brings a new flavor to web image search, with the feature called image similarity search. Once images are searched using keyword, the user can narrow down on the search results by searching for similar images. This will help the user find the most relevant image, and covers the limitation posed by pure keyword based image searches.

This blog, will discuss the development of the search engine and the technology behind it.

More details soon, watch this space for updates.
