    Hello,

    There are vertical lines in the hyperspectral images that I have performed (as can observed in the attached figure).

    I guess that is because the scanning is performed by lines? Can you give me more details about why the appearance of these lines and how to minimize this effect?

    Thanks
    Alex

      Alex,
      Hello! Yes lines are normal as it is a line scanning system. Meaning a line of data ( 1 pixel row) is collected at a time. But these lines are pretty heavy. Meaning the signal to noise ratio is low on the image.
      What are you imaging? Can you send an optical picture of what you are trying to scan?
      This will help me.
      Thanks!
      Jamie
