Hi David,
there is no such command for color images in ImageJ. Thresholding color
images is more complex.
In your situation (Task: select value 255/255/0 where others can only be
0/255/0 or 255/0/0) I would prefer to create a gray scale image and work
on this.
Use
ImageProcessor ip2 = imp.getProcessor().convertToByteProcessor();
ImagePlus imp2 = new ImagePlus("Gray", ip2);
to create a 8bit image with the weights wR/wG/wB = 1/1/1.
Regards,
Peter
