Details：
The Random Pattern (Noise) Test chart for measuring texture sharpness has several key features.
（1）It contains slanted edges (2:1 and 4:1 contrast) for convenient comparisons with the dead leaves pattern.
（2）The gray area to the left and right of the dead leaves pattern has the same mean density as the dead leaves pattern, allowing it to be used for effective noise PSD removal using the McElvain et. al. technique.（3）Registration marks and 16 grayscale patches are included. The linear levels used to create the grayscale patches are 0 through 255 in steps of 17 (same as the Siemens Star chart in the draft of the upcoming ISO 12233 standard).
