Problem in thresholding an image
显示 更早的评论
Hi all
I am facing problem in thresholding an image such that in image 1 belongs to background and 0 belongs to foreground pixel.I have computed thresholded now i wan to satify the foreground equation like that
image>=threshold
how can I do it?such that 0 belongs to foreground in this image(black) and 1 belongs to background(white.) image is 576x720 and threshold computed is 576x720.
Thanks

Can you upload your image somewhere?

Like this:
foregroundImage = yourImage < threshold; % Can use <= if you want.
The foreground will be black (this is opposite to the normal way of foreground being white).
If your image has teh "foreground" as 0 and background as 1, then you'd do this:
foregroundImage = yourImage == 0;
but in that case it sounds like your image has already been thresholded.
