Filtering images and raw values

Lee, Joonsung
Dear all,

Hello, I've used two functions 'Bandpass Filter' (my setting is the same as in the official ImageJ website) and 'Unsharp Mask' (Radius = 2, Mask Weight = 0.5) to get more clear images (.DICOM).

I'm just wondering after filtering images through the two functions, are values of measurements (area and length of straight lines) different from the raw images as image filtering might affect the number of pixels?

Best wishes,
Joonsung Lee
