#X text 29 56 Description: apply dynamic thresholds to pixes for binarization;
#X text 15 89 pix_threshold_bernsen is a dynamic tiled threshold filter. Each tile's threshold is taken of the mean of the min and max value of a surrounding (2*tile_size) square tile. If a pixels value is higher than the threshold \, this pixel is set to 1 else to 0;
