A friend of mine was evaluating OCR software and finally decided to go with FineReader. I was curious what would happen if we put the RadCaptcha control in. Will the advanced OCR manage to decode it or not? At first he showed me a test run with the RadCaptcha demo description, to get an idea of the basic output:
Naturally, the captured description text was no problem - only a few characters were misread but then corrected with the spellcheck. Next, the real test was performed:
These were only a couple of the results, but there is no need to post the rest of the tests - none of the RadCaptcha images were recognized by the OCR software. Here are the CaptchaImage settings used in the tests:
As you can see, it cannot get any easier than this.
On a different note, the first Q1 2010 Service Pack release for our ASP.NET AJAX controls is out now. The RadCaptcha control received an update to its audio feature - the control will attempt to play the audio file directly in the browser via HTML5 audio or the QuickTime plug-in where available. You can "hear" the difference on our updated online demos.
