Inspire Mask
The Inspire mask masks pixels above background and is the mask used during data
acquisition in INSPIRE. This mask is available to understand what is being masked
during collection and is not generally used for feature calculations.
Note: this mask is new in IDEAS versions 4.0 or later.
Intensity Mask
The Intensity mask masks pixels between the lower and upper raw intensity thresholds
not background subtracted. See also “Threshold Mask” on page 204.
In the example below, cell #10678 is bright and cell #11992 is dim. The 50%
Threshold mask is similar for both images whereas the Intensity mask 250+ is quite
different, since only a few pixels in the dim image are greater than 250 counts, while
most of the metaphase plates in the bright image are masked.
