OpenCV通过函数cv2.face.EigenFaceRecognizer_create()生成特征脸识别器实例模型,然后应用cv2.face_FaceRecognizer.train()函数完成训练,最后用cv2.face_FaceRecognizer.predict()函数完成人脸识别。 1.函数cv2.face.EigenFaceRecognizer_create() 函数cv2.face.EigenFaceRecognizer_create()的语法格式为: retval = cv2.fa...

The Monte Carlo method can be used to estimate the multiplication factor, and other eigenvalues, for a nuclear system. In this chapter we present two methods for estimate the eigenvalues of a nuclear system and give implementations for slab geometry. The fission cycle approach uses the definition...
