Thresholding Dialog

Description

Thresholding Dialog allows to set thresholding function parameters that will be automatically written in Processing Script section text area.

How to get it

Select thresholding into the Script popup menu

Options:

•Standard Thresholding:

choose Standard Thresholding and fix a threshold value;

•Auto Thresholding:

choose Auto Thresholding and setting the kind of algorithm (either Otsu or Lloyd or Ridler and Calvard or Uniform Error or Standard Deviation or Clustering or Median);

•PEI Thresholding:

choose PEI Thresholding (requires hardware board installation) and selecting existing parameters file or custom parameters string;

•Common parameters for next methods:

Set contrast, brightness and local area size to use

•Dynamic Thresholding Minmax:

choose Dynamic Thresholding Minmax algorithm;

•Dynamic Thresholding Average:

choose Dynamic Thresholding Average algorithm;

•Adaptive Thresholding Minmax:

choose Adaptive Thresholding Minmax algorithm;

•Adaptive Thresholding Average:

choose Adaptive Thresholding Average algorithm;

•Adaptive Thresholding BackTrak:

choose Adaptive Thresholding BackTrak algorithm;

•Advanced Thresholding Deviation

choose Advanced Thresholding Deviation algorithm;

•Advanced Thresholding Variance

choose Advanced Thresholding Variance algorithm;

•Fore and Back Clustering Thresholding

choose Fore and Back Clustering Thresholding algorithm;

•Background Tracking Thresholding Minmax

choose Background Tracking Thresholding algorithm;

•Background Tracking Thresholding Average

choose Background Tracking Thresholding algorithm and set min max range and contrast percentage;

•Edge Thresholding:

choose Edge Thresholding algorithm and set sensitivity and max spot size;

•Refine threshold with tolerance:

Set tolerance

Note

Set -1 to auto calculate value for Contrast, Brightness, Sensitivity, Min, Max and Tolerance

Each thresholding algorithm has own plus and is adapt to some circumstance: the suggestion is to make several attempts on the batch to choose right algorithm and right parameters.
