Visualize the bounding box

Is it possible to plot/display the bounding box around the face according with the test data's scale and center?

Thank you.

The issue asks to visualize bounding boxes from test data. First, locate the test data loading and preprocessing code to understand the scale and center values. Then, examine existing plotting utilities in the repository or integrate a simple visualization using Torch's image display or an external library. The output should show the face image with the bounding box overlaid according to the provided parameters.
