How to Threshold a grayscale image in java

[Chulaka Gunasekara]

Hi all,

Can somebody tell me how to threshold a grayscale image in java. I'm
new to image Processing and am stuck in a project. If you guys can
help me with a source code or algorithm it would be wonderful....

Hello,

Please take a look at the online documentation for menu or macro  
driven thresholding...

http://rsb.info.nih.gov/ij/docs/menus/image.html#adjust

or if you want to really use Java then you'll need to dive into  
ImageJ's source code - see ...

ImageProcessor.setThreshold() in http://rsb.info.nih.gov/ij/developer/ 
api/index.html

Cheers,
Ben
