Dynamic Threshold Functions

Dynamic threshold modes provide the same functionality as other seg-
mentation modes with the added advantage of adaptive threshold. A dynamic
threshold is particularly useful when there are lighting variations from one
image to another because the threshold is defined as a percentage of the pixel
distribution, not a range of light values.

l

A dynamic threshold is set as a percentage of the total pixels in the
Image.

l

To properly set a dynamic threshold, initially use an image that provides
an "ideal blob" to determine what percentage of the image contains blob
pixel values.
