calculates the mask using SVM

Parameters

model	struct svm_model which is used
input	input image
radius	radius for calculation of mask, smaller value results in higher resolution but longer calculation time
threshold	thresold value, lower value will reject more values
resize_dimension	the image is resized for calculation that the bigger dimension is small than resize_dimension
adaptThreshold	if true then the threshold is changed, if the all values are higher than threshold

Returns

vigra::BImage, which contains the masks
