📚 Description

This model is designed to detect melanoma from skin lesion images. It processes input images of size 224x224 pixels and outputs a binary classification indicating whether the lesion is melanoma or not. The model is trained to differentiate between malignant melanoma and benign conditions.

🔍 Use Cases

1. Medical Diagnosis: 🏥 Assisting dermatologists in diagnosing melanoma from images.
2. Skin Cancer Screening: 🩺 Enhancing early detection efforts in large-scale skin cancer screening programs.
3. Patient Monitoring: 👩‍⚕️ Helping in monitoring patients with a history of melanoma or high risk.

💡 How to Use

1. Preprocess the Image: Resize and normalize the image to 224x224 pixels with pixel values between 0 and 1.
2. Feed the Image: Input the preprocessed image into the model.
3. Interpret the Output: Analyze the output to determine if the lesion is melanoma or not.

Loading the Model

To use the model, first, load it using your preferred framework.

import tensorflow as tf

# Load the pre-trained model
model = tf.keras.models.load_model('path/to/Melanoma-003.keras')

Preprocessing the Input

Preprocess the input image to fit the model's requirements.

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

def preprocess_image(img_path):
    # Load the image
    img = image.load_img(img_path, target_size=(224, 224))
    # Convert to numpy array
    img_array = image.img_to_array(img)
    # Normalize the image
    img_array = img_array / 255.0
    # Reshape to add batch dimension
    img_array = np.expand_dims(img_array, axis=0)
    return img_array

# Example usage
img_path = 'path/to/your/image.jpg'
processed_image = preprocess_image(img_path)

Making Predictions

Use the model to predict if the lesion is melanoma.

# Predict the class
prediction = model.predict(processed_image)

# Interpret the result
if prediction[0] > 0.5:
    print('The lesion is classified as Melanoma.')
else:
    print('The lesion is classified as Not Melanoma.')

Full Example

Combining all steps into a single example.

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

# Load the pre-trained model
model = tf.keras.models.load_model('path/to/MelanomaDetectionModel.h5')

def preprocess_image(img_path):
    img = image.load_img(img_path, target_size=(224, 224))
    img_array = image.img_to_array(img)
    img_array = img_array / 255.0
    img_array = np.expand_dims(img_array, axis=0)
    return img_array

img_path = 'path/to/your/image.jpg'
processed_image = preprocess_image(img_path)

prediction = model.predict(processed_image)
if prediction[0] > 0.5:
    print('The lesion is classified as Melanoma.')
else:
    print('The lesion is classified as Not Melanoma.')
