[magick-users] MSE in ImageMagick

[Vishnu Prasan]

Hi all,

I am trying to find the MSE between two Jpeg2000 codestream images (.j2c).
How when ever I try using the following command

compare -metric MSE xyz.j2c abc.j2c NULL

I get the following error
compare: no decode delegate for this image format 'xyz.j2x'
 compare: no decode delegate for this image format 'abc.j2x'
compare: missing filename 'NULL'

If i try it without NULL i get some errors as well that file abc does not
exist. I am aware that Imagemagick does support the Jpeg 2000 codestream. So
I am wondering how to calculate this ?. If i try this for BMP images I get
the MSE

Thanks

Vishnu
