MASK FILE DESCRIPTION

Masks can be saved in JSON based files.

Example :

 { "mask" : {
   "type" : "2D" or "3D",
   "size" : [x, y] or [x,y,z],
   "pointsNum" : number of points around center in mask,
   "points" : [vector of pixels/voxels numbers],
   "coefs" : [vector of mask coeficients],
   "center" : [number of center pixel or voxel]
 }

• We assume that the first pixel/voxel of data has number 0. Than every other pixel/voxel we can obtain by : number = floor(j) + floor(k)*width + floor(l)*width*height

  where width and height is the size of processing data and j,k,l are points on sphere or circle of the mask. For more info please look to octave_utils/maskGenerator

• There are more points to one pixel/voxel size area in mask. The sum of coeficients of this area have to equals one.

• There are 8 points in area for 3D MASK and 4 points for 2D MASK

• 2D MASK can't be used in MAIN module at this time, but we are working on it.
