2016-03-30 09:33:09 -0600 | commented question | What is the best practice for cropping the positive examples to train a HOG classifier? Just as i tried(,maybe not the best practise), at first i used some cropping tools( you can Google it) to crop your positive or negative Training samples. Of course you should try to hold the aspect ratoin as good as you can. After Training your model with just cropped Images you can use your model than, go get more Trainings samples if it works. Just repeat it one more times, you can get enought samples. Hope it helps you. |

2016-03-26 08:01:22 -0600 | asked a question | Android 3.1 ANN_MLP HoG Descriptor Hello everyone, I'm working now at a pattern recognition Project and using ANN_MLP. I trained this model at frist with Opencv3.1 and using HoG as feature extractor in Windows and after that I was trying to load in it in Android. For Android I use the OpenCV-3.1.0-android-sdk. I've googled and it shows that since Java opencv 2.4 there is no load method for StatModel object. So i tried to load it with JNI. Here I have two questions: 1. When i create a HoG descriptor instance using the following codes, ========================================================== [I got the fatal exception:] ========================================================== 2. In JNI loading model function, I use this method ========================================================== So I don't konw how to covert ANN_MLP instance to jlong, this is the compliling error Any Inputs will be appreciated!
