I need your help in some of the terms, i have also read your paper on "Vehicle detection combining gradient analysis and<br />AdaBoost classification". Its a wonderful work sir, i need your help in detecting objects(such as vehicles) at the rear end of a car. Im using haar tranforms and adaboost algorithm for the object detection. is this approach correct or do i need to make some changes?? kindly reply.Unknownhttps://www.blogger.com/profile/02569997945561549433noreply@blogger.comtag:blogger.com,1999:blog-6314876008291942531.post-46182091450289431792011-02-20T21:05:38.158-08:002011-02-20T21:05:38.158-08:00Hi
