operator for segmenting the wound area of a scratch assay image
input image
image to be segmented
horizontal scratch
is scratch horizontally oriented (else it is assumed to be vertically oriented)
entropy filter size
size of entropy filter mask
increase lets the scratch area decrease
sigma
standard deviation of gauss filter
increase leads to more image smoothing and scratch area tends to decrease
maximum iterations
maximum number of iterations for level set segmentation
don't check for scratch presence
don't check for scratch presence prior to segmentation
deactivate, if built-in check for scratch presence fails
alternative: train a new svm model, cf. Scratch Assay SVM Trainer
use external svm file
should an external svm file be used for classification
the automatic scratch detection uses a built-in support vector machine model to decide whether an image contains a scratch or not, if this detection doesn't work properly an external model file created with the Scratch Assay SVM Trainer can be used for this task
external svm file
absolute path to an external svm model file
Verbose
