Would someone be able to give me some info or a link etc ... regarding haarlets aka Haar wavelet-like features. I'm reading several papers for my master dissertation and several of these papers briefly mention haarlets. I can't seem to really get what they are and how they are used. I apologize if this is a basic question. But i would really appreciate some clear, structured info on the subject.
Have you seen Robust Real-time Object Detection by Viola and Jones? This is probably the most widely used face detection algorithm, and also the most famous example of the use of the Haar wavelet-like features.
The Haar wavelet is used for edge detection and edge detection is a common problem in image processing, specially for pattern recognition. Haarlets are recommended for that purpose. As an example, this project uses haarlets to achieve that:
