Set the size and position of the window in units of 1 pixel.
· If a circle or ellipse is selected in item
1
, then the two variables you need to
set are center and diameter.
Decide whether a mask window will be employed and if so which type (rectangular, round or
elliptical).
· A mask window exists inside the boundary of the measurement window and screens out
those parts of the image which are not needed in the measurement process.
Select the measurement window type: RECTANGLE (rectangular), CIRCLE (circular)
or ELLIPSE (ellipse).
Set the size and position of the mask window (which is framed with a dotted line) in units of
1 pixel.
· If a circle or ellipse was selected in item
1
, then the two variables you need to set are
center and diameter.
· It is possible to enter dimensions that make the mask window bigger than the
measurement window.

Select whether to invert the black and white in the image: YES or NO.
· NO means the white area will be measured after the image has been converted to binary
values.
· YES means the black area will be measured after the image has been converted to binary
values.
Select either fixed or threshold value correction as the binary conversion processing
method. (VAR-DIFF or VAR-RATE).

AREA FILTER
r
UPPER MENU
After the labeling, the area filter is a function used to identify small islands whose area is
less than a specified amount. It eliminates them from the object which is being measured.
Set the maximum number of pixels. Enter any number from 0 to 245760.
· To enter number, select
e
AREA FILTER using up and down keys, and press the SET
key twice. Select a required digit using the left and right keys, and select the required
figure using the up and down keys.

elimination cycles)
Select a method for eliminating binary noise.
-
See methods for eliminating noise from binary images, expansion/contraction
and eliminating binary noise in shared settings on page 9·10.
Set the number of cycles that the binary noise elimination process will be carried
out (0 to 5). Enter number of times for expansion and contraction, separately.
