I don't know what and how I should write
pkg load image. I guess this is my problem, as someone told me.
I think that I can't process images now.
I checked and yes: I have just that setup.exe (
Octave-3.2.4_i686-pc-mingw32_gcc-4.4.0_setup )
So that is correct. For example this works:
summer = imread('summer.jpg');
imshow(summer);
I will see great summer picture!!
I want to use for example commands imhist and im2double - but it seems that
Octave can't find those commands. ?
Here are results from Octave command line;
octave-3.2.4.exe:1> pkg load image error: package image is not installed
error: called from:
error: C:\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\pkg\pkg.m at line 2005,
column 4
error: C:\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\pkg\pkg.m at line 301,
column 7
octave-3.2.4.exe:1> help imhist
error: help: `imhist' not found I THINK THIS IS STRANGE
octave-3.2.4.exe:1> help im2double
error: help: `im2double' not found I THINK THIS IS STRANGE
octave-3.2.4.exe:1> im2double help
error: `im2double' undefined near line 1 column 1
octave-3.2.4.exe:2> kesa = imread('kesa.jpg');
octave-3.2.4.exe:3> imshow(kesa); THIS WORKS!!!
I want to form a negative of my color picture summer.jpg and print it on the
screen.
And finally to form bitlevels 1-8 to summer.jpg and print it on the screen
That's it, nothing more.
Please, help
