% Read the images or stack of images using the ImageJ library.
% Files must be in TIFF (uncompressed), PNG, GIF, JPEG, DICOM, BMP, PGM or FITS
% format TIFF images can be 1-bit, 8-bits, 16-bits (unsigned), 32-bit
% (real) or RGB color.
% The image could read from the disk (filename) or from a URL (url). If no
% parameter are given to this function, the program open a dialog box to
% choose a image file.
% Example:
% im = mijread;
% im = mijread('http://www.google.com/intl/en_ALL/images/logo.gif');

% Part of the package MIJ

% Installation:
% 1. Put the ij.jar (ImageJ) in the folder java of Matlab
% 2. Put the MIJ.class (MIJ) in the folder java of Matlab
