ithresh

Interactive image threshold

ithresh(im) displays the image im in a window with a slider which adjusts the binary threshold.

ithresh(im, T) as above but the initial threshold is set to T.

im2 = ithresh(im) as above but returns the thresholded image after the "done" button in the GUI is pressed.

[im2,T] = ithresh(im) as above but also returns the threshold value.

Notes

• Greyscale image only.
• For a uint8 class image the slider range is 0 to 255.
• For a floating point class image the slider range is 0 to 1.0
• The GUI only displays the "done" button if output arguments are requested, otherwise the threshold window operates independently.
