Image preloaded as night_image.

The Cascade of classifiers class from feature module has been already imported. The same is true for the show_detected_face() function, that is used to display the face marked in the image and crop so it can be shown separately.

Instructions

100 XP
  • Load the trained file from the data module.
  • Initialize the detector cascade with the trained file.
  • Detect the faces in the image, setting the minimum size of the searching window to 10 pixels and 200 pixels for the maximum.
