Detailed Description

class PerfusionMask

This class provides functions to determine a brain mask from the MRI perfusion images.

The mask is obtained as follows:

1. 3D gaussian filtering of the last volume of the sequence with a standard deviation sigma
2. Binarization with a threshold value equal to (100*thres)% of the maximum amplitude of the filtered volume
3. Conversion of the result to a bucket form (i.e. a list of 3D points)

Constructor.

The constructor initializes the gaussian standard deviation and the threshold value

Parameters

s	is the floating sigma value
t	is the floating threshold value given as a multiplicative factor of the maximum amplitude of the filtered volume
