Digitze points on an image using the mouse.

File Information

DIGITIZE07(filename) displays an image and allows the user to digitize points using the mouse, similar to MATLAB's built-in GINPUT and other digitizers available at Matlab Central's File Exchange.

The main new feature of this version is that points are draggable; this permits fine tuning of already digitized points using the zoom feature. Other features adopted from previous versions include:
- Import previously digitized points
- Export digitized points to the workspace or file
- Interactively change the marker color, size, and shape
- Pin digitized points (i.e. toggle draggable mode)
- Delete unwanted points by right-clicking on the point
- Fully interactive GUI: Errors are reported to dialog boxes rather than to the Workspace


Digitize2.M and Draggable inspired this file.

This file inspired Ginput2.M V3.1 (Nov 2009).

Easy to use - just open the script in MATLAB and click "Run".

You can customise the point markers and zoom in and out easily using the zoom button and the scroll wheel.

Note that it will not digitize graphs, and scale selected points according to selected axes. The best Mathworks File Exchange code I have found for this job is "digitize2.m".

Hello everyone!!! I'm student in Greece and I am a new user of MATLAB...
Which type of files are recognized by IMREAD??
Can I call "digitize07(filename)" in the command window?
When we says "filename", we means the path where the file exists?
And finally, we must put the image file as a viriable?
(sorry for bad English)

This is a great digitizing tool and being able to adjust the position of a point is a great feature. I have not be able to figure out how to modify it so it could be used as a callable sub-routine that would return the XY values. Is that possible to do with a GUI oriented program?

Does not work on UNIX. Please amend lines 157,167 to use fullfile:

[x,map] = imread([matlabroot,'\toolbox\matlab\icons\pin_icon.gif']);
% should be[x,map] = imread(fullfile(matlabroot,'toolbox','matlab','icons','pin_icon.gif'));

Very Good
I am just wondering if it could include labelling of the points?
