The neural network model, upon receiving the image set, analyzes and processes the image set to identify areas of wear, degrees of wear, and other relevant characteristics in the image. These results are then output and may be visually reported in numerical, graphical, or other form. These output results provide researchers with detailed information and quantitative data about the wear condition of solar panels.
