我正在尝试使用NormalBayesClassifier对Foscam 9821W网络摄像头生成的图像进行分类.它们是1280x720,最初是彩色的,但我将它们转换为灰度分类.
我有一些Python代码(在http://pastebin.com/YxYWRMGs上)试图迭代一组火腿/垃圾邮件图像来训练分类器,但每当我调用train()时,OpenCV会尝试分配大量的内存并引发异常.
mock@behemoth:~/OpenFos/code/experiments$ ./cvbayes.py --ham=../training/ham --spam=../training/spam
Image is a <type 'numpy.ndarray'> (720, 1280)

*** trying to train with 8 images
responses is [2, 2, 2, 2, 2, 2, 1, 1]
