Detailed Description

The ImageAnalysisFilter component provides a video filter that utilizes deep learning models to analyze video frames received by the VideoOutput component.

This component is in beta. Elements are subject to change in future releases.

The following code sample analyzes video frames collected from the device's camera.

Page {
    property url modelFileUrl: AppFramework.fileInfo("~/ArcGIS/Data/leaf_classifier.tflite").url

    Camera {
        id: camera
    }

    ImageAnalysisFilter {
        id: imageAnalysisFilter

        interval: 250

        analyzer {
            modelSource: modelFileUrl
            minimumScore: 0.5
        }

        overlay {
            visible: true
            font {
                family: Qt.application.font.family
            }
        }

        resultsModel {
            unique: false
        }

        cameraOrientation: camera.orientation
        videoOrientation: videoOutput.orientation

        onDetected: {
            console.log("Detected:", JSON.stringify(result));
        }
    }

    VideoOutput {
        source: camera
        filters: [ imageAnalysisFilter ]
        anchors.fill: parent
