# Example usage calculate_crack_features('path_to_your_image.png') This example assumes a lot of steps are already taken care of (like having a clear image of the crack, and a method to accurately extract and analyze it). In real scenarios, especially with complex materials like LBE, you might need to integrate domain-specific knowledge and more advanced image analysis or machine learning techniques. lbe crack
