Description

The operator partition_linespartition_linesPartitionLinesPartitionLinespartition_lines divides lines into two sets according to various criteria. For each input line the indicated features (FeatureFeatureFeaturefeaturefeature) are calculated. If each (OperationOperationOperationoperationoperation = 'and'"and""and""and""and") or at least one (OperationOperationOperationoperationoperation = 'or'"or""or""or""or") of the calculated features is within the given limits (MinMinMinminmin,MaxMaxMaxmaxmax) the line is transferred into the first set (parameters RowBeginOutRowBeginOutRowBeginOutrowBeginOutrow_begin_out to ColEndOutColEndOutColEndOutcolEndOutcol_end_out), otherwise into the second set (parameters FailRowBOutFailRowBOutFailRowBOutfailRowBOutfail_row_bout to FailColEOutFailColEOutFailColEOutfailColEOutfail_col_eout). The default values 'min'"min""min""min""min" and 'max'"max""max""max""max" of the parameters MinMinMinminmin and MaxMaxMaxmaxmax are used to leave bottom and top limit, respectively, open. Possible values for FeatureFeatureFeaturefeaturefeature:

'length'

(Euclidean) length of the line

'row'

Line index of the center

'column'

Column index of the center

'phi'

Orientation of the line

Attention

If only one feature is used the value of OperationOperationOperationoperationoperation is meaningless. Several features are processed according to the sequence in which they are passed.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Result

The operator partition_linespartition_linesPartitionLinesPartitionLinespartition_lines returns the value 2 ( H_MSG_TRUE) if the parameter values are correct. Otherwise an exception is raised.
