2020-03-29 09:27:37 -0600	answered a question	Missing HOG Cascade in Ver 3 From the version >3.4 traincascade is not supported anymore in OpenCV (also for Haar and LBP cascades training). BUT
2020-03-29 06:16:33 -0600	commented answer	Human detector using HAAR cascades has too many false positives it is confident about Thanks Pablo! Our cascade outperform OpenCV standard ones :) Overview: http://www.vision-ary.net/2015/03/largest-booste

2020-03-29 06:10:32 -0600	answered a question	Can someone explain me these terms (acceptanceRatio, HR, FA) in training haar cascade, and "acceptanceRatio 800:4.97153e-05" is it consider good? Take a look here on how to handle the acceptanceRatio and the False acceptanceRatio in opencv traincascade: http://ww
2020-03-29 06:08:41 -0600	answered a question	Training Haar cascades for face detection.. The parameters and the neg. samples you choose will lead you to a poor cascade: 100%. Take a look here for a more sophi

2020-03-29 06:02:08 -0600	commented answer	How the HoG features work with AdaBoost in openCV? No more development since years but companies worldwide still use a lot the cascade approach. I can suggest to use the O
2020-03-29 05:55:55 -0600	answered a question	traincascade's error (Required leaf false alarm rate achieved. Branch training terminated.) The training parameter setting is completely wrong. Take a look here to understand how the exponential decreasing of the
2020-03-29 05:51:41 -0600	answered a question	Cannot detect cars Training a real usage cascade is not trivial, number of samples and model size are fundamental in creating something mea
2020-03-29 05:44:06 -0600	answered a question	[OSX] Can't find opencv_createsamples & opencv_traincascade I can suggest to use an earlier versions of OpenCV to train the cascades, I'm still using the traincascade in Opencv 2.4

2020-03-29 05:24:53 -0600	answered a question	Passengers counting in car using opencv The open source world is moving massively to deep learning approaches without considering the "old school" methods are (
2020-03-29 05:21:45 -0600	answered a question	How to tracking multiple vehicle (e.g car and motorcycle) using haar cascade classifier? Yes it is possible both options: - 1 xml for 1 category - 1 xml for many categories. The rigid objects approach have
2020-03-29 05:17:01 -0600	answered a question	Is there a way to use a trained CascadeClassifier for just classification in OpenCV 3.x? Yes it is possible with some limitation. We still suggest to use a very small scale progression around the object to be
