TIFF16 image looks different in windows file viewer and MATLAB -

-

general problem description

i have 33 tiff16 images , want processing on them using matlab. reading them first step. after download image web , try read using matlab's imread (as tiff , read). display image using imshow. image displayed windows file viewer , matlab totally different. cannot process them since don't trust matlab has read them correctly. give more specifics of problem now.

edit: if helps, details of tiff16 images are: tiff (16 bits per channel, prophoto rgb color space, lossless compression)

more details:

i download image a0008-wp_crw_3959.tif. destination: go this link -> img0008 -> expert b (in case wants try, otherwise have screenshots below).

i read image in matlab using: img=imread('imgfilename.tif','tiff'); imshow(img,[]); or

t = tiff('imgfilename.tif','r'); imagedata = read(t); imshow(imagedata);

now, display snapshots of windows file viewer:

enter image description here

next, snapshot of matlab shows me:

enter image description here

now, have reason believe windows file viewer correct. go same link previous. scroll down img0008. hover mouse onto leftmost img0008. thumbnail view of expert b come looks same windows shows me.

does know how make matlab read , show tiff16 image correctly?

thank @markransom pointing me embedded color profile possibility. believe following solution correct , produces same output windows file viewer.

first read icc-color-profile using iccread command. 

i_rgb = imread('a0008-wp_crw_3959.tif'); outprof = iccread('srgb.icm'); p = iccread('a0008-wp_crw_3959.tif');

then convert image srgb profile using makecform , applycform:

c = makecform('icc',p,outprof); i_cmyk = applycform(i_rgb,c); imwrite(i_cmyk,'pep_cmyk.tif','tif') info = imfinfo('pep_cmyk.tif'); imshow('pep_cmyk.tif');

the original image saved on disk , new - pep_cmyk.tif - same windows file viewer.
