What does a threshold value does to an image.
I mean if choose a particular intensity value as threshold value and if apply the threshold value to the image,
What does the threshold value make changes in the image
for example..
I have an image with min and max value of intensity as x1 and y1.
A particular region in that image has min and max intensity values as a1 and b1.
If I only want to highlight the particular region I need to apply a threshold value to the entire image.
So can one guide me out on how and on what basis to choose the threshold value for this image..
thanks
