MpatSetAccuracy

This function sets the specified model's search parameter for positional accuracy and the complexity of the image. You can enhance speed performance by selecting a lower positional accuracy. Also, whenever the positional accuracy of a model changes, the effect of any preprocessing is undone. Therefore, if the accuracy is changed, call MpatPreprocModel() before searching for the model.

The positional accuracy is also slightly affected by the search speed (MpatSetSpeed()).

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

ModelId

Specifies the identifier of the model for which to change the positional accuracy search parameter.

Accuracy INQ

Specifies the required positional accuracy for the search.

This parameter must be set to one of the values below. Note, the precision achieved is dependent on the quality of the model and the image (the tolerances listed below are typical for high-quality, low-noise images).

For specifying the positional accuracy of the search
Value	Description
M_HIGH	Specifies a high accuracy (typically ± 0.05 pixels).
M_LOW	Specifies a low accuracy (typically ± 0.20 pixels). Note that when using this setting, the match scores can be slightly lower than usual. If a precise match score is important to you, use at least medium accuracy. (summarize) Specifies a low accuracy (typically ± 0.20 pixels). (more details...)
M_MEDIUM	Specifies a medium accuracy (typically ± 0.10 pixels). This is the default value. (summarize) Specifies a medium accuracy (typically ± 0.10 pixels). (more details...)
