How to split image?

[Ye Chen]

Hello,

Is there any  function or plugin in ImageJ available to split one image
into half from the middle? For example, if I have an image 512 by 512, I
need to split this image from the middle to get another two new images
which should be 256 by 512?

Thanks

Hi,

Such tasks are exactly what macros are for. Using the Macro Recorder
(Plugins -> Macros -> Record) together with the Built-in Macro Functions
list (http://rsb.info.nih.gov/ij/developer/macro/functions.html), I created
the following macro that does what you ask:

makeRectangle(0, 0, getWidth()/2, getHeight());
run("Copy");
run("Make Inverse");
run("Crop");
run("Internal Clipboard");

Or use the plugin OI_cut_RGBmerge
(http://valelab.ucsf.edu/~nico/ijplugins/OI_cut_RGBmerge.html) which
will also work on stacks and give you a Red-Green overlay of the two
halfs.

hi there,

I am new in ImageJ and now working on tracking vehicle
object from video.

One difficulty I met is: one vehicle might show as
multiple objects (very closed each other) as I use
ParticleAnalyzer.

I am thinking to change code to automatically combine
objects based on their locations.

I wonder if there is existing similar concept/tool in
ImageJ. Sorry if this question is silly.

thanks your time,

Michael,
