Blob Analyzer l Weighted pixels are shown as completely included within the Blob Image. Soft Thresholding Example 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. Dynamic Threshold Example ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 410
