Hello,

I am using Linux, I have tried exactly what you suggested, and I still cannot use "imread" or any function to load an image.

For example, my "path" above was:

"/usr/home/exps5/Pictures/OSUHat.jpg", but I also moved the photo to Desktop and home so I tried:

"/usr/home/exps5/Desktop/OSUHat.jpg" and "/usr/home/exps5/OSUHat.jpg"

I also noted the "pwd" and that is why I created a jpg in the home directory, which is where my Octave-workspace resides.

I tried: I = imread('/home/OSUHat.jpg')

I = imread('/home/exps5/Desktop/.OSUHat.jpg')

I = imread('/home/exps5/Pictures/OSUHat.jpg')

and others.

I still get the same error as mentioned originally.

The only time I get a different error is when I try: I = imread("OSUHat.jpg") when the director is /home/exps5. In that case, I get:

error: imread: invalid image file: /usr/lib/x84-64-linux-gnu/octave/3.8.2/oct/x86_64-pc-linux-gnu/__magick_read__.oct: failed to load: /usr/lib/x86_64-linux-gnu/octave/3.8.2/oct/x86_64-pc-linux-gnu/__magick_read__.oct: undefined symbol: _ZN6Magick5ColorC1Ehhh

error: /usr/share/ocatve/3.8.2/m/image/private/__imread__.m at line 181, column 7

error: /usr/share/octave/3.8.2/m/image/imread.m at line 107, column 30

I am a bit frustrated and confused since I am a newbie, but I seem to be doing the same as you.

or Octave 4.0.0 on Windows, the following works for me:

(check where you are)

>> pwd

ans = c:\temp

if i'm in the same directory as the file

>>imread('test.bmp');

if I'm not in the same directorry as the file:

imread('c:\temp\test.bmp');

if I'm in the directory 'under the file'

>> pwd

ans = c:\

imread('.\temp\test.bmp');

and you can change directory with the cd command.

Or, assuming you're using a version of Octave with the GUI, you can navigate with the file/folder tree in the upper left pane.

if you're still having a problem, you'll have to show us exactly what you're entering so we can see where the error might be.

Try to test with no spaces in the path or filename

f=imread('/tmp/palm.jpg');

Hello,

I have tried to load an image into Octave using:

I = imread ("path of image");

I get the following error messages:

error: imread: cannot find "path of image"

I have also tried:

IMAGE_PATH("path") with no success.

Help would be greatly appreciated! I am completely new to Octave.
