Instructions
Use the worksheet for the filter you have values for
For example, if you know values for the (3x3 or 5x5) convolution matrix for the
Low pass filter use the Enter Low Pass Filter Values worksheet
High pass filter use the Enter High Pass Filter Values worksheet
Sharpening filter use the Enter Sharpening Filter Values worksheet
Each worksheet will calculate values for the other two convolution matrices
You will also need to enter values for
the sharpening factor, f (using the drop down list of fractions from 1/10 to 1)
any estimated values for the Low Pass Filter when working with known values for the High Pass Filter
,High Pass Filter
