I have download images from DDSM screening mammograms which are in .LJPEG format. How can I open and view that images

please help me

Thanks

Has anyone found a solution to this? I really need a way to import those data to matlab?

I don't know that format, and neither does imread, unless it's really a jpeg2000 format. Try renaming the extension to one of these and see if imread will read it:

EXT       ISA     INFO        READ      WRITE     ALPHA  DESCRIPTION                     
-----------------------------------------------------------------------------------------
j2c j2k   isjp2   imjp2info   readjp2   writej2c  0      JPEG 2000 (raw codestream)
jp2       isjp2   imjp2info   readjp2   writejp2  0      JPEG 2000 (Part 1)
jpf jpx   isjp2   imjp2info   readjp2             0      JPEG 2000 (Part 2)

Not so good news: looks like .LJPEG files are produced by broken software.

you can search CBIS-DDSM dataset or MIASDbv1(Suckling et.al.) Breast can mammography images. I tried lots in DDSM (LJPEG to JPEG),but the decompressor file, their specified link is not reachable nowadays.

CBIS-DDSM(https://wiki.cancerimagingarchive.net/display/Public/CBIS-DDSM)

MIASDbv1(https://www.repository.cam.ac.uk/handle/1810/250394?show=full)

In DDSM(http://www.eng.usf.edu/cvprg/Mammography/Database.html),

You need to get a reader for that type of file. As of R2011b (what I'm using now) it doesn't appear that imread() handles that format. Search the internet to see if anyone has written a MATLAB function to read that type of file format.
