 Unsupported data encoding.

This enhancement has been incorporated in Release 2010b (R2010b). For previous product releases, read below for any possible workarounds:

JPEG-2000 encoded images are not supported in the Image Processing Toolbox 6.4 (R2009b). To work around the issue, use another program to convert the image to a supported format before reading it in using MATLAB.
