DermaNet: Age and Gender Prediction from Skin Images

Welcome to DermaNet! A deep learning model designed to predict the age and gender of individuals based on skin lesion images. Powered by advanced Convolutional Neural Networks (CNNs), DermaNet provides accurate and reliable predictions that can be useful for dermatology research, personalized skincare, and more.

🚀 Key Features

• Age Prediction: DermaNet estimates the approximate age of individuals based on their skin images, allowing for age-related analysis.
• Gender Prediction: It predicts the gender of individuals (male, female, or unknown), providing valuable demographic insights.
• High-Quality Model: Built on a robust CNN architecture with preprocessing techniques like CLAHE (Contrast Limited Adaptive Histogram Equalization) and Gaussian Blurring for enhanced image quality.
• User-Friendly Interface: Easy-to-use scripts for prediction and analysis, making it accessible to researchers and practitioners alike.

🧠 Model Architecture

DermaNet utilizes a state-of-the-art Convolutional Neural Network (CNN) for feature extraction and prediction tasks:

• Convolutional Layers: Learn intricate patterns in skin images.
• Max-Pooling Layers: Reduce dimensionality and computational cost.
• Batch Normalization: Speed up training and improve generalization.
• Fully Connected Layers: Perform the final predictions for age and gender.
• Dropout Regularization: Reduce overfitting and improve robustness.

🖼️ How It Works

1. Image Preprocessing: Images are enhanced using CLAHE for better contrast, resized to 256x256 pixels, and normalized for deep learning.
2. Model Training: The model is trained on a large dataset of annotated skin images, learning the correlation between age, gender, and skin features.
3. Prediction: After training, the model predicts the age and gender of new images based on learned patterns.

📊 Results & Performance

• Age Prediction: Achieved a low Mean Absolute Error (MAE) for precise age estimation.
• Gender Prediction: High classification accuracy for predicting gender (male, female, or unknown).

📂 How to Use

1. Clone the Repository

git clone https://github.com/Alokbpandey/DermaNet.git
cd DermaNet

2. Install Dependencies

Ensure you have the required libraries installed:

pip install -r requirements.txt

3. Load the Pre-trained Model

The pre-trained model is saved as DermaNet.h5. You can load it as follows:

from tensorflow.keras.models import load_model
model = load_model('DermaNet.h5')

4. Make Predictions

Predict the age and gender of a new image:

from tensorflow.keras.preprocessing import image
import numpy as np

img_path = 'path_to_image.jpg'
img = image.load_img(img_path, target_size=(256, 256))
img_array = image.img_to_array(img) / 255.0
img_array = np.expand_dims(img_array, axis=0)

age_pred, gender_pred = model.predict(img_array)
print(f"Predicted Age: {age_pred}")
print(f"Predicted Gender: {['Male', 'Female', 'Unknown'][np.argmax(gender_pred)]}")

⚙️ Technologies Used

• TensorFlow/Keras: For building and training the deep learning model.
• OpenCV: For image preprocessing and enhancement.
• Matplotlib: For visualizing training performance.
• NumPy: For efficient numerical computations.

📈 Training History

• Age MAE: The training and validation Mean Absolute Error (MAE) for age prediction.
• Gender Accuracy: The training and validation accuracy for gender classification.

🚧 Limitations

• Image Quality: Performance may degrade with poor-quality or distorted images.
• Age Range: Predictions are approximate and may not always be precise for every individual.
• Dataset Bias: Results depend on the diversity and quality of the training dataset.
