Python OpenCV-Eigenfaces人脸识别

标签: python python-2.7 opencv

我正在尝试使用Python和OpenCV创建简单的Eigenfaces人脸识别应用程序。不幸的是,当我尝试玩应用程序时,我得到了结果: (-1, '\n', 1.7976931348623157e+308),其中-1代表未找到且充满信心...相当高...

有人可以将Eigenfaces的最基本的OpenCV实现放吗?

这是我解决问题的方法。我使用的是Python2,这是官方文档中建议的(由于P3的某些问题)。

import cv2 as cv
import numpy as np
import os

num_components = 10
threshold = 10.0

faceRecognizer = cv.face_EigenFaceRecognizer.create(num_components, threshold)
images = []
labels = []
textLabels = ["Person1", "Person2", "Person3"]

destinedIm = cv.imread("images/set1/1.jpg", cv.IMREAD_GRAYSCALE)
destinedSize = destinedIm.shape

#Person1
img = cv.imread("images/set1/1.jpg", cv.IMREAD_GRAYSCALE)
imResized = cv.resize(img, destinedSize)
images.append(imResized)
labels.append(0)

#In similar way I read total 8 images of set1 and 6 images of set2 (2 different people, with label 0 and 1 respectively)

cv.imwrite("images/set2/resized.jpg", imResized) #this doesn't work

numpyImages = np.array(images)
numpyLabels = np.array(labels)
# cv.face_FaceRecognizer.train(self=faceRecognizer, src=images, labels=labels)
faceRecognizer.train(src=images, labels=numpyLabels)

testImage = cv.imread("images/set1/testIm.jpg", cv.IMREAD_GRAYSCALE)
# cv.face_FaceRecognizer.predict()
resultLabel, resultConfidence = faceRecognizer.predict(testImage)

print (resultLabel, "\n" ,resultConfidence)

testImage是标签= 0;的人的另一幅图像。

我会查看 testImage 的大小。此外,我使用了与您使用的不同的尺寸调整方法并使其正常工作。

    face_resized = cv2.resize(img, (299, 299))
