Thread Subject: how to read from curernt directory

hey.

I basically make an executable standalone file and i CAN
use it on other computers. the only problem is the PATH i
have set for a picture to be read.

 path1='C:\Documents and Settings\Talal Khan\My
Documents\MATLAB\TTT.jpeg';

 path2='C:\Documents and Settings\Talal Khan\My
Documents\MATLAB\wall.JPEG';

%%later they are converted to grayscale images.

 SRC1=loadGrayScaleImage(path1);
 SRC2=loadGrayScaleImage(path2);


Obviously other pc's will not have these paths in their
computers. i want to read the file TTT.jpeg and wall.JPEG
from the directory i copy the standalone program, not from
the directories already set in path1 and path2.

how can i do that?

how can it read these files from the current directory on
the computer,and not having to set a fixed path?

path1='TTT.jpeg';
path2='wall.JPEG';

i know thats what i thought i wud do but when i do this it
still gives me an error... something like this i dono what
cud it be....

Error using ==> imread at 315
File "Call11.jpeg" does not exist.

Error in ==> loadGrayScaleImage at 25
MYIMAGE=imread(path);

Error in ==> talaltest2>pushbutton5_Callback at 976
SRC2=loadGrayScaleImage(path2);

make sure the file is in the same folder as the .m file
you're running... you could try putting a 'dir' command in
there just to get a file listing to make sure you're not
going crazy.

yeah they in the same directory...i think it has to do
somethin with the loadGrayScaleImage.m.....



this is wahts in the loadGrayScaleImage.m

----------------------------------------------------------





function [MYIMAGE] = loadGrayScaleImage(path)
%the FUNCTION loadGrayScaleImage accepts a string (path)
and loads the image found in that path. In the case that
% the image is a color image , it is converted to gray
scale image. THe foramt of the imag is adjusted so that it
is
% compatible with the function in the image processing
MATLAB toolbox (i.e the range of intnsities is in the
% range of 0-1.
%
% inputs:
% path - The path for loading the image
%
% outputs:
% MYIMAGE, the image loaded
%
%



% replace the first letter of the full path with the first
letter of the current pathg
% this will make sure that we het the correctsave path
eventhough the drive letter on
% a different machine is difefrent
currentpath=pwd;
path(1)=currentpath(1);


% load the image
MYIMAGE=imread(path);


% in the case that the image is color image, convert it to
gray scale image
if (isrgb(MYIMAGE)==1)
    MYIMAGE = rgb2gray(MYIMAGE);
end


%arrange the image intensities so that they are in the
range of 0-1, since MATLAB requies the image intensities
%to be in that range in order to be able to use MATLAB
image processing functions
if(isa(MYIMAGE,'uint8') == 1)
   MYIMAGE = double(MYIMAGE) / 256;
else
   MYIMAGE = double(MYIMAGE);
end
if ( ((max(max(max(MYIMAGE)))) > 1) | ((min(min(min
(MYIMAGE)))) < 0) )
   error('All images used in Machine Vision toolbox must
contain pixels on the interval [0,1]');
end
