Training BDI material
On this page you will find teaching materials for the module "Basics of Digital Imaging"
What you can do with this image:
- look at the repetitive pattern of the roof, draw horizontal intensity profiles on different positions or at the same position at different image scalings: Nyquist theorem
- point at the dark area below the train and the headlights: an area of the image with black or saturated pixels contains no structural information (although we know that there must be structure in both areas)
- play with different contrast, reduce the bitdepth and check the image histogram to demonstrate the loss of information
- save the image in different file formats and then substract from the original to demonstrate how the information change
