looking for free software to interactively extract models from images with

2013-03-01 Thread Dan Hitt

Hi All,

I'm looking for a piece of free software that can display images
(such as jpg) and interactively extract data (or form models)
from them.

So this would be something like the measure tool in gimp,
but much more involved: instead of having a single line segment
which you compare with the horizontal (as in the gimp),
you could form and save complexes of points and lines.

Saved along with these complexes would be their
associated lengths and angles, and you could then use them
on other images (such as by identifying
corresponding points on two different photographs). Perhaps
other options would include some kind of transform, so that
you might select the vertices of a quadrilateral and transform
the images so that your four-sided figure becomes a rectangle.

So i'd be grateful for any suggestions on what piece of free
software comes closest to being able to do this.

Or, if this is the wrong group, please steer me (but i'm
asking here because the people who post here have such
a breadth of knowledge about so many topics).

(I think i'd prefer something compiled over something interpreted,
and probably something written in python over something
written in java, but beggars cannot be choosers, so interested
in any leads whatsoever.)

Thanks in advance!

dan

I assume od stands for 'output device/drive/disk', and I guess it's a
Windows-specific extension - under Unix/Linux, everything is considered
to be a file, so it's not needed.

So you've succeeded now? Cool. I don't think I've ever used the
graphical installer myself; mostly it looks like it's just a prettier
version of exactly the same thing, and I'm not too worried about
prettiness :-) Plus it means that a whole bunch of extra hardware (video
card and mouse, anyway) have to be behaving at install time.

Re: Install failed - USB flash to USB drive [SOLVED]

I successfully installed this:

to a USB flash in Windows with this:

dd bs=1M if=debian-live-6.0.6-amd64-lxde-desktop.iso od=e:

The problem is in the GUI installer. To do the installation successfully, use

Linux has had them about that long, too :-)

I'm not familiar with LWDE (or LXDE, which I've actually heard of), but
the multiple windows/desktops provided by an X desktop are generally
layered on top; they're not the same thing as the kernel-level VTs.

Ctrl-alt-F1 is the most likely way to get back to it, as described in my
 previous post.

Yes. I don't know which VT it will be on, but there's a good chance
it'll be there. It might have scrolled off the top of the screen, of
course - shift-PgUp may be able to scroll up to see it.

> If you have a suggestion, I'll try it.

No others at this stage, unfortunately. I may chip in where I have
something useful to add, but you don't want my help on stuff I don't
understand, right? :-)

> Should I try the Debian Installer again and, when the GRUB installer

Try all of them. F2 through F12. The Ctrl key is only needed when X has
control of the VT, but it doesn't seem to cause a problem otherwise.

I don't know what useful info the installer may put on each VT, but
there's a good chance it will give you something.

Linux has the concept of virtual terminals (VTs). Alt-F switches
between them, as long as they're in text mode (regardless of whether
it's commandline or full-screen). If the X server is running (Gnome,
LXDE, whatever) in the active VT, then you need to add Ctrl- to that, to
stop the X server grabbing the keystrokes.

To summarise:
On a text console, use Alt-F to choose a VT.
In graphical (X) mode, use Ctrl-Alt-F instead.

Note that not all VTs 1-12 will have anything running on them, and we
can't necessarily tell what your system is running on each.

On a normal running system (mine, anyway):
1-6 will have text terminals which you can log into
7 has X

So I can use Ctrl-Alt-F1 to get the first, and Alt-F7 to get back to X.
If I try 8-12, I just get a flashing cursor.

On the install system, the same features are used a bit differently:
* the main installer generally runs in the first terminal.
* often there's a commandline you can start in the second (eg hit alt-f2
and it will say 'Press enter to activate this console' or something -
then you can type exit when you're finished)
* There may be more of those on further terminals; I can't remember.
* Often one terminal will display syslog information.
* Another, I think, displays installer log information.

So you can do quite a bit of debugging if required.

He never read about the how and why of things. His idea

Never once did I hear him ask why an antenna must be

It was all along the lines of "I spent X Dollars for this or

List members told him about articles he could read,
suggested he contact somebody locally who could help show him
the ropes as to how to do these things right, etc.

Finally, I think everybody just gave up. He left the
list and I have no idea what happened but this present
discussion reminds me much of that very similar discussion. We
were all jerks and just out for ourselves.

In the 35 years I have been involved with modern
computing, my experience has been that if you show you are

point you at a good reading list and many times, they do a lot
more than the call of duty says they should do.

I think that is exactly the case. This guy managed to get everybody in

Yup.  And it's even obvious what he's doing, but he's too obstinate to listen.

(trying to install onto the same device he's booting from, without paying 
attention to partitioning, telling the installer where to put things, or 
telling grub that it has to worry about two different installs on the same 
device - idiot)


Of course I'm not trying to install to the same device from which I'm booting. 
What's with you, Miles? Why are you making such stupid assumptions and then

 Assuming you are using the standard Debian installer in text mode, you
 may want to check for more details about the failure by pressing
 Alt+F4 (I think it is 4, rather than 2 or 3) immediately after the
 installer gives the error (Alt+F1 returns you to the installer).

To help further with this, we will need clarification on the error you are
getting from the grub install.  There are many reasons it can fail and
without specifics, we can't assist.


Assuming you are using the standard Debian installer in text mode, you
may want to check for more details about the failure by pressing
Alt+F4 (I think it is 4, rather than 2 or 3) immediately after the
installer gives the error (Alt+F1 returns you to the installer).


I'm running the Debian installer that's built into a Debian Live ISO image 
that's been raw written (dd) to a USB flash drive. Thus, I'm not running it 
from a command line. I boot the USB flash drive and click on the desktop icon 
identified as the Debian Installer. I do not do any prepartitioning or 
preformatting except upon retry after a failure. When I retry after a failure, 
the live OS automounts the target's existing partitions (that had been created 
during the previous try). I found that unmounting those existing partitions 
doesn't work. I have to run the installer, delete the partitions, then reboot, 
then rerun the installer.

I have no idea what problem the GRUB installer encounters. I have no 
opportunity to press Alt+F4 as the installer automatically runs full-screen and 
I can't get back to the LXDE desktop until I back out of the installer and quit.

Hmmm... Perhaps I can press Alt+F4 when the error occurs. I wasn't instructed 
to do that, and I don't know what Alt+F4 does since I'm not a Linux user, but I 
can try it. I'll quit Windows, reboot to USB, and try it stay tuned... I'll 
be right back.


I'm back. Things have changed. When I booted Debian Live, it wouldn't recognize 
the USB hard drive when I plugged it in. I quit, rebooted Windows, and looked 
at it with Disk Manager. The USB hard drive is there with all its partitions. 
I'll boot back to Debian Live and try again, but I'd say that something Debian 
has broken. We'll see, eh?
Stay tuned. I'll be right back.


Shane,

I'm back. When the GRUB install failed I pressed Alt+F4. The Debian Installer 
disappeared and I was immediately back to the LWDE desktop. I tried Alt+F4 
there and nothing happened.

Is there a Debian installer that runs in Windows?

 If I put the same in c code, it works

 #include 
 int main() {
 fputs("\033[4masdfasdf",stdout);
 return 0;
 }

 I get underlined text.

Sorry - fail with copy/paste and attempting to fix annoying line wraps -
which only appear in my mailer.
