labeling images -- general advice

[nitro_n2o]

hi all,
i need some general advice/direction on this.
I want to be able to draw boxes on images to label some features, say faces, so that i can tell exactly the position of a face in a photo..
Any ideas on how can i do this? perhaps a package or something like that.. but lets not do it in Java

is openCV capable of doing something like this? or imagemagick?

thx

ImageMagick can certainly draw on existing images. If you are asking if it can identify specific parts of a photo to be labeled, it cannot do that.

sorry if my question wasn't clear enough
i want to be able to draw boxes on pictures using the mouse and then get the coordinates of the box i've just drawn

something like an object marker..

thx, any help is appreciated

You could do this using Tkinter and python (the canvas widget would let you do it pretty easilly). Other GUI toolboxes probably have something similar (QT, wxWidgets, etc.).

The ImageMagic command line tools are more useful for making non-interactive changes to image files. It does include GUI tools, but these seem like they are geared more for experimenting with how certain commands work.

I recommend you use OpenCV:

http://sourceforge.net/projects/opencvlibrary/
http://opencvlibrary.sourceforge.net/
http://en.wikipedia.org/wiki/OpenCV
http://www.cs.iit.edu/~agam/cs512/lect-notes/opencv-intro/index.html

these are all general tutorials and docs about OpenCV, none of them has good detail about doing what i want to do, but thx anyways nice list

it's probably too late, but this tool does what you want to do

http://robotik.inflomatik.info/guides.html
http://robotik.inflomatik.info/other/opencv/OpenCV_ObjectDetection_Demo.exe

it's compiled for windows, but it includes source code and I could run it under wine
