how aboult result

[CLIsVeryOK]

the data in hdf format is stored in BGR not RGB, hdf data is single format and has a relation with uint8 RGB data as : RGB = (SingleHdf + 1.6) * 80. I am not sure, but for me, it works.

[liuziwei7]

Yes, the data in HDF5 file is stored in the BGR order channel-wise for accommodating with the Caffe convention. The value of the images has been normalized as: data = data * (3.2/255) - 1.6 .

Also, the script for crop&align face images ("align_face_celeba.m") has been uploaded to the repository.
