Amber Status

12.10.2012

Full install of mousetrap complete. Config file was manipulated to include failed dependency on 'python-opencv' which has been updated and the package is now referred to as 'cv'. Other dependencies are outdated or the names have been changed as well (xlib-python, etc). New errors with 'gobject' have been identified. Here is the recorded error when running mousetrap:


 ImportError: could not import gobject
 (error was: ImportError('When using gi.repository you must not import static modules like "gobject".

Will attempt to remove instances of broken dependency opencv to the newer cv


12.17.2012

Bug for pygobject is here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649861

  • The fix is to upgrade to version 3 of gtk?
  • Changed line in configure.in file to AM_CHECK_PYMOD(cv,,,[AC_MSG_ERROR(Could not find python module cv)]) to fix opencv problem when creating make files
  • Highgui no longer exists in the new API for cv (once known as opencv) and it should just be called as cv.whatever.
  • cvCreateCameraCapture() no longer exists, replaced with cv.CaptureFromCAM().

New Error

  • In this particular file: widgets.py, we actually want to import gobject directly and type_register the Mapper using gobject. After doing this, I have the Window pop up and now a new error has come up.

and this:

I believe this is explained in this reported bug: https://bugs.launchpad.net/bzr-gtk/+bug/923824

  • There is a whole big issue with dependencies surrounding pygobject, pygtk, and gtk that are causing errors.


12.20.2012

Looked into error with pygobject, gtk and pygtk and found that the import gi must be the first import in main.py

1.9.2013

Looks like there are some inconsistencies with opencv. Going through and removing outdated methods. I was also looking to see how the camera is initiated, reading through code.

1.11.2013

Was able to get rid of the small_img error after trying several adaptations of opencv methods.

  • cvSize no longer exists and the python tuple (int, int) should be used instead.

Have new error:

  • Point no longer exists in the python version of the api. Now tuples are used. Looking into how the points are used in the program to see if it can be changed.

1.17.2013

1.21.2013

  • Fixed most of the Point errors; make sure cvPoint is just a python tuple
  • Load() is the new cvLoadHaarClassifierCascade()
  • The points variable in _ocv.py looks like this: ((173, 130, 145, 145), 15) but it is used as if it was a series of points, so that was changed to r[0][0] and so forth.

Some examples of point errors/changes:

  • TermCriteria doesn't exist, and there's little documentation on the method on how to create the calculation for optical flow for the new version of cv.

Description of CalcOpticalFlowPyrLK()

  • Does not have an example or descriptive errors when fails.
 Parameters:	
 prevImg – first 8-bit input image or pyramid constructed by buildOpticalFlowPyramid().
 nextImg – second input image or pyramid of the same size and the same type as prevImg.
 prevPts – vector of 2D points for which the flow needs to be found; point coordinates must be single-precision floating-point numbers.
 nextPts – output vector of 2D points (with single-precision floating-point coordinates) containing the calculated new positions of input features in the second image; when OPTFLOW_USE_INITIAL_FLOW flag is passed, the vector must have the same size as in the input.
 status – output status vector; each element of the vector is set to 1 if the flow for the corresponding features has been found, otherwise, it is set to 0.
 err – output vector of errors; each element of the vector is set to an error for the corresponding feature, type of the error measure can be set in flags parameter; if the flow wasn’t found then the error is not defined (use the status parameter to find such cases).
 winSize – size of the search window at each pyramid level.
 maxLevel – 0-based maximal pyramid level number; if set to 0, pyramids are not used (single level), if set to 1, two levels are used, and so on; if pyramids are passed to input then algorithm will use as many levels as pyramids have but no more than maxLevel.
 criteria – parameter, specifying the termination criteria of the iterative search algorithm (after the specified maximum number of iterations criteria.maxCount or when the search window moves by less than criteria.epsilon.
 flags –
 operation flags:
 OPTFLOW_USE_INITIAL_FLOW uses initial estimations, stored in nextPts; if the flag is not set, then prevPts is copied to nextPts and is considered the initial estimate.
 OPTFLOW_LK_GET_MIN_EIGENVALS use minimum eigen values as an error measure (see minEigThreshold description); if the flag is not set, then L1 distance between patches around the original and a moved point, divided by number of pixels in a window, is used as a error measure.
 minEigThreshold – the algorithm calculates the minimum eigen value of a 2x2 normal matrix of optical flow equations (this matrix is called a spatial gradient matrix in [Bouguet00]), divided by number of pixels in a window; if this value is less than minEigThreshold, then a corresponding feature is filtered out and its flow is not processed, so it allows to remove bad points and get a performance boost

  • Noted that mousetrap and gnome-mousetrap are in the Ubuntu repository. Ignoring this and following instructions provided by the MouseTrap GNOME Live! project page…
  • Installation went as expected. Ran into every issue in the 'Troubleshooting' table, but that seems to be expected behavior.
  • Running MouseTrap with command 'mousetrap'. Expected errors due to lack of webcam. Otherwise seems to run without issue (preferences window pops up when button clicked, and so forth).
  • Quits without issue.

Thoughts on Install Process:

  • Noted that it might be nice if they add the commands for the RPM package manager to the instructions.
  • "Troubleshooting" should be a link to the Troubleshooting section for user-friendliness.
  • 'Dependency hell' is tedious. Due to the fact that MouseTrap is in the Ubuntu repositories suggests it might be in others as well. It might be useful to include this fact in the install instructions.
  • Else it might be useful for the autogen.sh shell file to automatically detect if a package is installed (it already does this) and installs them if they are not. This will run into an issue with different package management systems. A different shell file for the popular ones (APT and RPM)?
  • A GUI installer would be the most user-friendly, but that's not the Linux MO.

  • Webcam received and set up. Seems to be recognized OOTB on Ubuntu -- the light goes on when in use, etc.
  • When running Mousetrap, it shows a blank window (most of the time) or a frozen video frame (only seen this once). In the terminal, it repeatedly displays errors similar to this;
Corrupt JPEG data: 1 extraneous bytes before marker 0xd9
  • When running again with webcam unplugged, it runs fine.

1/25/13

Replaced Ubuntu with Fedora 18 on system. Webcam works out of the box. Everything works nicely. Except for the new UI for Anaconda, but I digress. Had issues installing Mousetrap. Full details below...

Installing Fedora:

I downloaded the ISO image for the Fedora 18 Network Install CD from here http://fedoraproject.org/en/get-fedora-options#formats. This is good if you have fast internet access. This is ideal since a) it's a small(er) download, and b) dd takes a while (see below).

Instead of a CD/DVD, I decided to use a USB stick. I used the Fedora-suggested LiveUSB tool, but it produced a USB stick that either a) is not recognized as bootable, or b) freezes at or after the "Secure boot not enabled" screen. So I used dd instead (a nifty tool, which should already be installed if you're using a UNIX-based OS, that copies a disk image to a destination byte-for-byte). To put the .iso image onto my USB stick, I used the command,

# dd if=./Fedora-18-x86_64-netinst.iso of=/etc/rdisk1

I had to be root to do this (hence the # above). Note that I also put "r" before the device name (in the above example, I used rdisk1 instead of disk1). This enables direct access, which speeds things up considerably. I used

$ fdisk -l

to find out the location of the USB drive.

Once I executed the dd command, it sat there seemingly doing nothing. dd can take a while (hence the reason I didn't use the Live DVD ISO!).

After it was done, booted from the USB drive, followed the (horrid) Anaconda installation process (beware of the terrifying partitioning part!).

After that's done, booted up and installed the b43 driver for my wireless card using the guide here, http://linuxwireless.org/en/users/Drivers/b43#Fedora. Everything works great, including the webcam.

Installing Mousetrap:

I attempted to install all the dependencies listed on the Mousetrap GNOME Live! site using the usual yum install <package>. However pygtk, python-pyspi and libglib2.0 are not in the repos.

  Install method
 Install Dependencies:
 * gnome-common
 * glib2-devel
 * intltool
 * python-devel
 * opencv-python
 * change configure.in file to look for cv instead of opencv
 Run Commands:
 -> run ./autogen.sh
 -> make
 -> make install
 -> run mousetrap from /src
 (let me know if this works for you --Amber)

Nicole's Status

Fedora 18 was successfully installed. Instructions are now on the "Getting Started" page.

MouseTrap was fully installed. Instructions are now on the "Getting Started" page. I encountered the same first error:

 ImportError: could not import gobject (error was: ImportError('When using gi.repository you must not import static modules

  • Amber, have you put up your latest fork onto your github yet?
 Yes, do you have git installed? (Not really sure how much git you know, so I'll just put up instructions for all.)
 If not, open a terminal, become root
 cd to /opt
 mkdir git  (just fyi you can put your repo anywhere, this is just how I was taught)
 run yum install git-core
 cd into git folder
 run git clone git://github.com/amberheilman/mousetrap.git
 now you have pulled down my code.
 To start using the code I'm currently working on:
 run:
 git checkout fix_install (my branch)
 git pull
 * DO NOT MAKE CHANGES HERE (we should all be working in separate branches)
 git branch INSERT_BRANCH_NAME (this clones my branch and creates a new one)
 git checkout INSERT_BRANCH_NAME (this opens up your branch that you just created)
 git branch (now you can see the branch your in with a *, and all others under this git repo)
 * We should also be making commits on a frequent basis with commit titles that show exactly what was changed
 * Hope this helps
