Compute Accuracy For Object Detection

detectedFeatures

(Required)

The input polygon feature service layer containing the objects detected from the Detect Objects Using Deep Learning tool.

Syntax: A JSON object describing the detectedFeatures feature surface layer. At least one type of input must be provided in the JSON object. If multiple inputs are given, the itemId takes priority.

  }
}

groundTruthFeatures

(Required)

The polygon feature service layer containing ground truth data.

Syntax: A JSON object describing the groundTruthFeatures feature service layer. At least one type of input must be provided in the JSON object. If multiple inputs are given, the itemId takes priority.

    "folderId":"sdfwerfbd3ec25584d0d8f4"
  }
}

outAccuracyTableName

(Required)

The name of the output accuracy table.

Syntax: A JSON object describing the output accuracy table.

Example:

1
{"serviceProperties": {"name": "accuracy_table"}}

outAccuracyReportName

The name of the accuracy report that will be added as a portal item in PDF format.

Syntax: A JSON object describing the output accuracy report.

Example:

1
2
3
4
{"name":"accuracyReport"}

//Shared Data Path
{"uri": "/fileShares/yourFileShareFolderName/accuracyReport"}

detectedClassValueField

The name of the class value field in the detected objects feature service. If not specified, the tool will try to use the standard class value fields Classvalue and Value. If these fields do not exist, all features will be treated as the same object class.

Syntax: String.

Example

1
detectedClassValueField=ClassName

groundTruthClassValueField

The name of the class value field in the ground truth feature service. If not specified, the tool will try to use the standard class value fields Classvalue and Value. If these fields do not exist, all features will be treated as the same object class.

Syntax: String.

Example

1
groundTruthClassValueField=Class

minIoU

The Intersection over Union (IoU) ratio to use as a threshold to evaluate the accuracy of the object detection model. The numerator is the area of overlap between the predicted bounding box and the ground truth bounding box. The denominator is the area of union or the area encompassed by both bounding boxes. minIoU values rance from 0 to 1.

Syntax: Double.

Example

1
minIoU=0.5

maskFeatures

A polygon feature service layer that delineates the area where accuracy will be computed. Only the detected objects and ground truth data that falls completely within the polygons will be assessed for accuracy. If no feature service layer is provided, the full extent of the input feature services will be used.
