Open MV 例程里这个代码那一部分应该放对比的照片，那一部分放被对比的照片？求指教万分感谢

奥奥，是这样啊，那请问有没有摄像头识别人脸的源码

为什么运行时摄像头闪一下白光，就没反应了？求指教

@kidswong999 在 人脸识别，求指教 中说：

orl_faces

是这个文件夹吗 ？

@kidswong999 import sensor, time, image

SUB = "s2"
NUM_SUBJECTS = 5
NUM_SUBJECTS_IMGS = 10

img = image.Image("orl_faces/%s/wx.jpg"%(SUB)).mask_ellipse()
d0 = img.find_lbp((0, 0, img.width(), img.height()))
img = None

print("")
for s in range(1, NUM_SUBJECTS+1):
dist = 0
for i in range(2, NUM_SUBJECTS_IMGS+1):
img = image.Image("orl_faces/s%d/%d.pgm"%(s, i)).mask_ellipse()
d1 = img.find_lbp((0, 0, img.width(), img.height()))
dist += image.match_descriptor(d0, d1)
print("Average dist for subject %d: %d"%(s, dist/NUM_SUBJECTS_IMGS))
这是完整的代码

@驻扎 请问下 你解决这个问题了吗

SUB = "s2"
NUM_SUBJECTS = 5
NUM_SUBJECTS_IMGS = 10

img = image.Image("I/wx.pgm"%(SUB)).mask_ellipse()
d0 = img.find_lbp((0, 0, img.width(), img.height()))
img = None

print("")
for s in range(1, NUM_SUBJECTS+1):
dist = 0
for i in range(2, NUM_SUBJECTS_IMGS+1):
img = image.Image("orl_faces/s%d/%d.pgm"%(s, i)).mask_ellipse()
d1 = img.find_lbp((0, 0, img.width(), img.height()))
dist += image.match_descriptor(d0, d1)
print("Average dist for subject %d: %d"%(s, dist/NUM_SUBJECTS_IMGS))

img = image.Image("I/wx.pgm"%(SUB)).mask_ellipse()
img = image.Image("orl_faces/s%d/%d.pgm"%(s, i)).mask_ellipse()
这两句代码我应该怎么改啊，老提示错误，求指教

@kidswong999 我把SD卡插在了MV上，img = image.Image("orl_faces/I/wx"%(SUB)).mask_ellipse()可是提示 这样的错误，那我应该怎么改呢？麻烦提示一下

import sensor, time, image
SUB = "s2"
NUM_SUBJECTS = 5
NUM_SUBJECTS_IMGS = 10

img = image.Image("orl_faces/%s/1.pgm"%(SUB)).mask_ellipse()
d0 = img.find_lbp((0, 0, img.width(), img.height()))
img = None

print("")
for s in range(1, NUM_SUBJECTS+1):
dist = 0
for i in range(2, NUM_SUBJECTS_IMGS+1):
img = image.Image("orl_faces/s%d/%d.pgm"%(s, i)).mask_ellipse()
d1 = img.find_lbp((0, 0, img.width(), img.height()))
dist += image.match_descriptor(d0, d1)
print("Average dist for subject %d: %d"%(s, dist/NUM_SUBJECTS_IMGS))

img = image.Image("orl_faces/%s/1.pgm"%(SUB)).mask_ellipse()
img = image.Image("orl_faces/s%d/%d.pgm"%(s, i)).mask_ellipse()
我把上面这两句话改成下面这两句，运行时会出现错误，麻烦大佬告诉我哪里出了问题，谢谢。。。。
img = image.Image("C:/Users/wx/Desktop/wx.pgm"%(SUB)).mask_ellipse()
img = image.Image("C:/Users/wx/Desktop%d/%d.pgm"%(s, i)).mask_ellipse()
