GANs for Image Generation
Project Title : GANs for Image Generation
Objective:
To build a system using Generative Adversarial Networks (GANs) that can generate realistic images from random noise, mimicking real-world data like human faces, animals, or scenery.
What are GANs?
GANs (Generative Adversarial Networks) are a type of deep learning model with two networks:
Generator: Creates fake images.
Discriminator: Tries to distinguish between real and fake images. They train together in a competition until the generator gets good at fooling the discriminator.
Key Concepts:
Unsupervised learning.
Image generation from noise (latent space).
Deep learning architectures (CNNs).
Steps Involved:
Dataset Collection:
Use datasets like MNIST, CIFAR-10, CelebA, LSUN, or any image dataset depending on your goal.
Preprocessing:
Resize and normalize images.
Prepare batches for training (usually 64x64 or 128x128 pixel images).
Model Design:
Generator: Uses transposed convolutions to create images from random noise.
Discriminator: Uses CNN layers to classify real vs fake.
Train using adversarial loss (binary cross-entropy).
Training:
Alternate training both models: the generator gets better at creating images, and the discriminator gets better at detecting fakes.
After training, the generator can produce realistic-looking images from random inputs.
Evaluation:
Visual inspection of generated images.
Use metrics like Inception Score (IS) or Frechet Inception Distance (FID) for quality evaluation.
Applications:
Creating realistic art, faces, or scenery.
Data augmentation for training ML models.
Style transfer, super-resolution, and image-to-image translation.
Game and film content generation.
