Parameter Setting Description
Mask size
・
3×3 (Default)
・ 5×5
・ 7×7
Select the range of pixels which are used to extract the edge.
With a larger mask size, search is less affected by variation in pixels.
Edge level: Auto
・
ON (Default)
・ OFF
Select this check box to adjust [Edge level] automatically. If edges are
not detected under the auto settings, clear this check box and adjust
value of [Edge level].
Edge level 0 to 1024
Default: 20
This setting is enabled when the [Auto] check box is cleared in the
[Edge setting] area. Set the lower limit of edge level to recognize as
edge. Edges are recognized when their edge level is above this
value. The smaller the value, the easier it is to find edges. The larger
the value, the less noise will affect finding edges.
Noise removal
level
0 to 100
Default: 0
Specify the upper limit of noise level to eliminate. Noise whose noise
level is below this value will be eliminated.
In the noise removal process, edges are connected and
divided into a set of groups of line segments, and then these line seg-
ments are removed one by one from shorter segments.
Setting a larger value removes larger noise.
