Generating Human Faces

Generating Human Faces is a project which generates human faces based on a given dataset of human faces.

Structure of the project:

• Generator (Transposed Convolution) :- The purpose of the Generator is to generate images closest to the real images in the dataset. Uses Tanh as activation function.
• Discriminator (Convolution):- The purpose of the Discriminator is to discriminate the images generated by the Generator using the real images in dataset. Uses Sigmoid as an activation function.

Requirements:

Numpy(>=1.8.2) Pytorch (>= 1.5.0) Matplotlib (>= 3.1.0)
