DL_LocatePoints

Basic

Module: DL_LP

Executes a Locate Points model on a single input image.

Name Type Range Description
Input value
 inImage Image Input image
Input value
 inRoi Region* Limits the area where points may be located
Input value
 inModelId LocatePointsModelId Identifier of a Locate Points model
Input value
 inMinDetectionScore Real 0.0 - 1.0 Sets a minimum required score for a point to be returned
Input value
 inMinDistanceRatio Real* 0.01 - 1.0 Sets a minimum distance between the returned points defined as a portion of the Feature Size. If not set, a value determined during the training is used
Input value
 inOverlap Bool Cuts the image into more overlapping tiles, which improves results quality at the expense of extended execution time
Output value
 outLocations LocationArray Returns location of the found points
Output value
 outClassIds IntegerArray Returns ids of the found point classes
Output value
 outClassNames StringArray Returns names of the found point classes
Output value
 outScores RealArray Returns scores of the found points

Requirements

For input inImage only pixel formats are supported: 1⨯uint8, 3⨯uint8.

Read more about pixel formats in Image documentation.

Hints

  • It is recommended that the deep learning model is deployed with DL_LocatePoints_Deploy first and connected through the inModelId input.
  • If one decides not to use DL_LocatePoints_Deploy, then the model will be loaded in the first iteration. It will take up to several seconds.
  • Use inOverlap=False to increase execution speed at a cost of lower precision of results.

Remarks

This filter should not be executed along with running Deep Learning Service as it may result in degraded performance or even out-of-memory errors.

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
