## 💡 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.

```python
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.

```python
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.

```python
# 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.

```python
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.')
```
