1. A computer-implemented backlight face recognition method, comprising:
performing a face detection on each original face image in an original face image sample set to obtain a face frame corresponding to the original face image;
capturing the corresponding original face images from the original face image sample set based on each of the obtained face frames, and obtaining a new face image containing background pixels corresponding to each of the captured original face images from the original face image sample set;
preprocessing all the obtained new face images to obtain a backlight sample set and a normal lighting sample set; and
training a convolutional neural network using the backlight sample set and the normal lighting sample set until the convolutional neural network reaches a preset stopping condition.
