How to use

This image is useful to evaluate resolution and degradation with band-limitation of color-difference signal.The gravel paths and stone walls are suitable for checking resolution and sharpness. 

You can observe if there is degradation with band-limitation of color-difference signal by checking a variety of big and small tulips. In addition, tulip petals are suitable for checking vividness of colors and conditions of phase shifting of brightness signal.
