2015-01-20 06:12:49 -0600 | asked a question | Haar Feature-based Cascade Classifier XML file argument I'm working with face detection of Haar Feature-based Cascade Classifier. I have searched a lots but I still haven't found the exactly answer for the left_val and right_val in XML file (like this) The left_val and right_val are the return value of a feature ( alpha(i) * h(i) in Viola-jones paper), is it true. And if so, because h(i) is -1 or 1 so we must have left_val = - right_val but in face it isn't true. Can you guys give me some explanation to understand that? Thank you for your help! Sorry my English is not so good |
