I downloaded a 4-band 1m spatial resolution NAIP image from Earth Explorer. The default image format is jpeg2000. You can see the trees in the attached image appear grainy, more so than what you would expect from a TIFF image. I believe this may be a result of the compression algorithm. To test, I used the Copy Raster tool in ArcGIS to convert the jpeg2000 to TIFF. I specified "NONE" for the compression in the tool environment. Unfortunately, the image appeared the same, although I noticed that there is LZW compression associated with the TIFF. Is there a way to essentially "unpack" a jpeg2000 image to remove all compression? I am open to any software-based approach or programmatic (Python, R, or Matlab) approach.
