🎭 Simpsons Character Classifier

A deep learning and Computer Vision project that identifies Simpsons characters from images using Convolutional Neural Networks (CNN)

🎯 Overview

This project uses deep learning to classify images of Simpsons characters. Built with TensorFlow/Keras and deployed with a Flask web interface, it can identify the top 10 most common Simpsons characters with high accuracy.

The model uses a Convolutional Neural Network (CNN) architecture trained on thousands of images to recognize distinctive features of each character.

Supported Characters:

Homer Simpson
Bart Simpson
Marge Simpson
Lisa Simpson
Maggie Simpson
Ned Flanders
Charles Montgomery Burns
Moe Szyslak
Krusty the Clown
Principal Skinner

✨ Features

🤖 Deep Learning Model - Custom CNN architecture with 3 convolutional blocks
📸 Image Preprocessing - Automatic grayscale conversion and normalization
🎨 Web Interface - Beautiful, user-friendly Flask web application
📊 Confidence Scores - Shows prediction probabilities for all characters
🖼️ Drag & Drop Upload - Easy image upload with preview
⚡ Real-time Prediction - Fast inference using optimized model
📈 Data Augmentation - Enhanced training with image transformations
🎯 High Accuracy - Achieves ~85-90% validation accuracy

🎓 Model Training

Training Configuration:

# Hyperparameters
LEARNING_RATE = 0.001
MOMENTUM = 0.9
DECAY = 1e-7
BATCH_SIZE = 32
EPOCHS = 10

# Optimizer
optimizer = SGD(
    learning_rate=LEARNING_RATE,
    decay=DECAY,
    momentum=MOMENTUM,
    nesterov=True
)

# Loss Function
loss = 'binary_crossentropy'

# Metrics
metrics = ['accuracy']

Data Augmentation:

# Implemented augmentations:
- Random rotation (±15°)
- Width shift (±10%)
- Height shift (±10%)
- Horizontal flip
- Zoom (±10%)

Training Tips:

For Better Performance:

Increase Epochs - Train for 20-30 epochs for better convergence
Adjust Learning Rate - Use learning rate scheduler
More Data - Include more characters if needed
GPU Training - Significantly faster (10-20x speedup)

Prevent Overfitting:

Dropout Layers - Already included (0.2-0.5)
Early Stopping - Stop when validation loss plateaus
Data Augmentation - Already implemented
Regularization - Add L2 regularization if needed

Expected Training Time:

CPU: ~2-3 hours (10 epochs)
GPU (CUDA): ~15-20 minutes (10 epochs)
