# Model Card: Fine-Tuned InceptionV3, Xception, & ResNet50 for Human Decomposition Image Classification

These CNN models were developed for the classification of human decomposition images into six stages of human decay defined by Gelderman et al. (2018).

## Model Details

### Model Description

- **Developed by:** Anna-Maria Nau
- **Funded by:** National Institute of Justice
- **Model type:** CNNs for Image Classification
- **Base Model:** InceptionV3, Xception, and ResNet50 pretrained on ImageNet
- **Transfer Learning Method:** Two-step transfer learning: (1) freeze all pre-trained convolutional layers of the base model and train newly added classifier layers on custom dataset and (2) unfreeze all layers, and fine-tune model end-to-end on custom dataset.

## Usage
The stage of decay classification is bodypart specific, that is, for the head, torso, or limbs.
