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.
Specify the upper limit of noise level to eliminate. Noise whose
noise level is below this value will be eliminated.
0 to 100 In the noise removal process, edges are connected and
[0] divided into a set of groups of line segments, and then these
line segments are removed one by one from shorter segments.
Setting a larger value removes larger noise.
