我正在尝试训练 Haar Cascade 来检测手部。我有一个大小为 1000 的 vec 文件。我有 40 个正图像和 600 个负图像。我已经尝试过放弃我的正面形象和负面形象。当我运行以下命令时,我收到以下错误:
opencv_traincascade -data classifier -data classifier -vec samples.vec -bg negatives.txt
-numstages 20 -minHitRate 0.999 -maxFalseAlarmRate 0.5 -numPos 1000\ -numNeg 600 -w 80

中止(核心转储)
我尝试降低阳性计数并重新执行整个过程,但仍然收到相同的错误。有什么建议么?
顺便说一句:我正在关注以下教程:http ://coding-robin.de/2013/07/22/train-your-own-opencv-haar-classifier.html
谢谢
