Rotation confuses face recognition

Wed, 14 Dec 2011 00:44:00 +0000

I have around fifty thousand digital photos in my library, and it has become impractical to browse through them looking for some event, or some place, or some person. So other than archiving, there really is no value in collecting photos if you can’t go back and find the ones you are looking for.

A few years ago I switched to using Image Ingester Pro and Adobe Photoshop Lightroom to import and catalog my photos. Now one of the first things I do after importing photos, is to add keywords describing the event, the place, and the people. But, I still have tens of thousands of photos that have no keywords, and there is no easy or automated way to add keywords to these photos. One thing that can be automated is adding people keywords to photos based on automated face recognition.

DxO Optics Pro and Adobe Lightroom on Vista x64

I bought my first SLR camera, a Canon EOS 20D, and my first wide angle lens, a Canon EF-S 10-22, several years ago. Amongst the many articles and reviews I read, online and in magazines, I came across a product called DxO Optics Pro, a product that would supposedly correct, amongst other things, lens distortion. This seemed like the perfect tool to help me with my wide angle pictures that looked very “fishy eyed”. And since DxO, then version 4, was receiving good reviews, I decided to trial the product. In those days the DxO licensing model was to pay per camera body and per lens module, not a cheap investment, but I really liked the results and so I purchased the product.

Microsoft Expression Media / iView Media Pro to Adobe Photoshop Lightroom converter

Introduction:

Because of severe performance problems I experienced with both iView Media Pro and Microsoft Expression Media, I decided to switch to Adobe Lightroom.

Unfortunately Lightroom does not understand catalog sets nor does it understand people tags, so the transition is not that simple.

After I could not find a simple, or even complicated solution, I decided to write my own conversion application.

This application will convert hierarchical catalog sets into keywords, and will add people tags to keywords.
