From: Christian Eschermann on 14 May 2010 12:50 Hello, for 150 0-1-pictures I need the 0-1-arrays. I can watch the pictures by using "imshow" but "imread" doesn't work. _____________________________________________________________ [FileName, PathName] = uigetfile('*.mat','Daten auswählen'); A = importdata(FileName); imshow(A(:,:,50),[0 1]) ______________________________________________________________ imread(A(:,:,50),[0 1]) doesn't work. Why not? Is there any alternative? Thank you. Christian

A = IMREAD(FILENAME,FMT) reads a grayscale or color image from the file specified by the string FILENAME. If the file is not in the current directory, or in a directory on the MATLAB path, specify the full pathname. First argument is a file name.
