Description

This function selects or merges blobs that meet a specified criterion. These blobs will be included in or excluded from future operations (calculations or result retrieval), or deleted entirely from the result buffer. Selection criterion can be based on a calculated feature or on the current status of the blobs. MblobCalculate() must have been called at least once before calling this function.

If this function is not called at least once, all blobs are included by default. If there is more than one call to this function, the effect of the calls is cumulative unless M_INCLUDE_ONLY or M_EXCLUDE_ONLY is specified as the operation to perform.

Once a blob has been excluded, it can normally be re-included only by specifying M_INCLUDE or M_INCLUDE_ONLY in a future call to this function (with the correct criterion). However, if you change the processing mode of a result buffer (using MblobControl()), or use the result buffer with different images (in a call to MblobCalculate()), all results in the buffer are discarded and all blobs are re-included.

The limits of the blob selection criterion are set using the CondLow and CondHigh parameters. If the blobs were taken from a calibrated image, these parameters can be set in pixel units or world units. To set the units, use MblobControl() with M_INPUT_SELECT_UNITS. Note that if you set this control type to M_WORLD but you don't pass MblobSelect() a result buffer whose results were obtained from a calibrated target image, the function will generate an error.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.
Parameters
This function is not supported on the selected boards.
Parameters
BlobResId

Specifies the identifier of the blob analysis result buffer to use in the blob selection process.

Operation

Specifies the operation to perform on the specified blobs. This parameter can be set to one of the following.

function map For operations on blobs
CollapseValue Description
Collapse M_DELETE

Deletes blobs that meet the specified condition. M_DELETE affects only included blobs, unless otherwise stated by the SelectionCriterion parameter.

M_DELETE removes blobs permanently from the result buffer and, consequently, prevents these blobs from being re-included.

(summarize)
Collapse M_EXCLUDE

Excludes all blobs that meet the specified condition.

M_EXCLUDE affects only the status of currently included blobs.

(summarize)
Collapse M_EXCLUDE_ONLY

Excludes only those blobs that meet the specified condition and includes all others.

The exclusion does not consider the present status of blobs (whether they are excluded), except for blobs that have been deleted (M_DELETE), unless otherwise stated by the SelectionCriterion parameter.

(summarize)
Collapse M_INCLUDE

Includes all blobs that meet the specified condition.

M_INCLUDE affects only the status of currently excluded blobs.

(summarize)
Collapse M_INCLUDE_ONLY

Includes only those blobs that meet the specified condition and excludes all others.

The inclusion does not consider the present status of blobs (whether they are included), except for blobs that have been deleted (M_DELETE), unless otherwise stated by the SelectionCriterion parameter.

(summarize)
Collapse M_MERGE

Groups all the blobs that meet the specified condition.

Once grouped, the blobs are treated as one blob (a grouped blob). The grouped blob is assigned a unique blob label. Only features that were calculated for all the individual blobs in the group are re-calculated for the new grouped blob; calculations are made using the results of the individual blobs in the group.

Note that if you add a specified moment to the feature list (using MblobSelectMoment() with M_GRAYSCALE + M_CENTRAL, or with M_BINARY + M_CENTRAL) and M_SAVE_RUNS disabled, M_MERGE will not be able to perform the moment calculation.

Except when using M_EXCLUDED_BLOBS as the feature for selection, this grouping operation only applies to included blobs.

If you are using M_MERGE, you cannot use MblobControl() with M_BLOB_IDENTIFICATION set to M_LABELED_TOUCHING.

(summarize)
SelectionCriterion

Specifies the feature to use as part of the selection criterion or the status of the blobs to affect. See MblobSelectFeature(), MblobSelectFeret(), and MblobSelectMoment() for a full description of the features. The specified result buffer must already contain the results for the specified feature.

To use as part of the criterion a feature that has only a binary definition, select one of the following.
