vous en pensez quoi !!!c 'est une histoire de mise à jour de imshow??!!de la toolbox....
Code:

1 2 3 4 5 6 7 8 9 I=dicomread('CD-16.dcm'); imshow(I,'DisplayRange',[]); ??? Error using ==> imshow (ParseInputs) Invalid input arguments; see HELP IMSHOW Error in ==> C:\MATLAB6p5\toolbox\images\images\imshow.m On line 90 ==> [imtype, cdata, cdatamapping, clim, map, xdata, ydata, filename, ...
merci

Que retourne ceci ?

Code:

f = dicominfo('CD-16.dcm')

Tu peux attacher une de ces images (dans une archive zip) ?

1 pièce(s) jointe(s)

voila !!

Je vais peut-être dire une bêtise mais tu sembles avoir la version 6.5, or la syntaxe que tu utilises semble n'exister que depuis la R14.

Citation:

The imshow syntax in which you specify the display range of the imageimshow(I,[LOW HIGH])
has been augmented to use a parameter/value pair syntax
imshow(...,'DisplayRange',[LOW HIGH])

lien

Donc essayes simplement :

Code:

imshow(I,[]);

effectivement j'ai la version 6.5....
et ça marche mnt merci !!

par contre je rencontre un autre problème avec d 'autres images :
Code:

1 2 3 4 5 6 7 8 9 I=dicomread('CD-18.dcm'); imshow(I,[]); ??? Error using ==> imshow (ParseInputs) Unsupported dimension Error in ==> C:\MATLAB6p5\toolbox\images\images\imshow.m On line 90 ==> [imtype, cdata, cdatamapping, clim, map, xdata, ydata, filename, ...
