今天介绍一个在GAN中经常用的人脸数据集：
CelebFaces Attributes (CelebA) Dataset
来自于kaggle上的数据集介绍：
A popular component of computer vision and deep learning revolves around identifying faces for various applications from logging into your phone with your face or searching through surveillance images for a particular suspect. This dataset is great for training and testing models for face detection, particularly for recognising facial attributes such as finding people with brown hair, are smiling, or wearing glasses. Images cover large pose variations, background clutter, diverse people, supported by a large quantity of images and rich annotations. This data was originally collected by researchers at MMLAB, The Chinese University of Hong Kong (specific reference in Acknowledgment section).
Overall
202,599 number of face images of various celebrities
10,177 unique identities, but names of identities are not given
40 binary attribute annotations per image
5 landmark locations
下载下来的数据集是这样的：
这是数据集：
下面使用代码加载数据集，并且读取25张人脸
# load and plot faces
from os import listdir
from numpy import asarray
from PIL import Image
from matplotlib import pyplot
# load an image as an rgb numpy array
def load_image(filename):
# load image from file
image = Image.open(filename)
# convert to RGB, if needed
image = image.convert('RGB')
# convert to array
pixels = asarray(image)
return pixels
# load images and extract faces for all images in a directory
def load_faces(directory, n_faces):
faces = list()
# enumerate files
for filename in listdir(directory):
# load the image
pixels = load_image(directory + filename)
# store
faces.append(pixels)
# stop once we have enough
if len(faces) >= n_faces:
break
return asarray(faces)
# plot a list of loaded faces
def plot_faces(faces, n):
for i in range(n * n):
# define subplot
pyplot.subplot(n, n, 1 + i)
# turn off axis
pyplot.axis('off')
# plot raw pixel data
pyplot.imshow(faces[i])
pyplot.show()
# directory that contains all images
directory = r'your path'
# load and extract all faces
faces = load_faces(directory, 25)
print('Loaded: ', faces.shape)
# plot faces
plot_faces(faces, 5)
