ResMaskNet

Model Description

resmasknet combines residual masking with unet architecture to predict 7 facial emotion categories from images.

Model Details

  • Model Type: Convolutional Neural Network (CNN)
  • Architecture: Residual masking network with u-network. Output layer classifies 7 emotion categories
  • Input Size: 224x224 pixels
  • Framework: PyTorch

# Load Configs

# Test model
face_image = "path/to/your/test_image.jpg"  # Replace with your extracted face image that is [224, 224]

# Classification - [angry, disgust, fear, happy, sad, surprise, neutral]
emotions = emotion_detector.forward(face_image)
emotion_probabilities = torch.softmax(emotions, 1)
