描述
算子 select_linesselect_linesSelectLinesSelectLinesSelectLinesselect_lines chooses lines according to
various criteria. For every input line the indicated features
(FeatureFeatureFeatureFeaturefeaturefeature) are calculated. If each
(OperationOperationOperationOperationoperationoperation = 'and'"and""and""and""and""and") or at least one
(OperationOperationOperationOperationoperationoperation = 'or'"or""or""or""or""or") of the calculated features is within
the given limits (MinMinMinMinminmin,MaxMaxMaxMaxmaxmax) the line is
transferred into the output.
The default values 'min'"min""min""min""min""min" and 'max'"max""max""max""max""max" of the parameters
MinMinMinMinminmin and MaxMaxMaxMaxmaxmax are used to leave bottom and top limits,
respectively, open.
Condition:
Possible values for FeatureFeatureFeatureFeaturefeaturefeature:
- 'length'"length""length""length""length""length"
(Euclidean) length of the line
- 'row'"row""row""row""row""row"
Line index of the center
- 'column'"column""column""column""column""column"
Column index of the center
- 'phi'"phi""phi""phi""phi""phi"
Orientation of the line
()
注意
If only one feature is used the value of OperationOperationOperationOperationoperationoperation is
meaningless. Several features are processed according to the
sequence in which they are passed.
