TIEGoogleVision.RequestTypes

Declaration

property RequestTypes: TIEGRequestTypes;

Description

Specify which Google Vision detection operations to call:

Value	Google Feature	Description
iegrWebDetection	WEB_DETECTION	Run web detection
iegrSafeSearchDetection	SAFE_SEARCH_DETECTION	Run Safe Search to detect potentially unsafe or undesirable content
iegrLabelDetection	LABEL_DETECTION	Run label detection
iegrObjectLocalization	OBJECT_LOCALIZATION	Run localizer for object detection
iegrFaceDetection	FACE_DETECTION	Run face detection
iegrLandmarkDetection	LANDMARK_DETECTION	Run landmark detection
iegrLogoDetection	LOGO_DETECTION	Run logo detection
iegrTextDetection	TEXT_DETECTION	Run text detection / optical character recognition (OCR). Text detection is optimized for areas of text within a larger image; if the image is a document, use iegrDocumentTextDetection instead
iegrDocumentTextDetection	DOCUMENT_TEXT_DETECTION	Run dense text document OCR. Takes precedence over iegrTextDetection
iegrCropHintsDetection	CROP_HINTS	Run crop hints
iegrProductSearch	PRODUCT_SEARCH	Run Product Search (Unhandled)
iegrImageProperties	IMAGE_PROPERTIES	Compute a set of image properties, such as the image's dominant colors

Note: After changing the RequestTypes you must call ProcessImage again to update your results.

Default: [iegrFaceDetection, iegrLandmarkDetection, iegrLogoDetection, iegrLabelDetection,
iegrTextDetection, iegrSafeSearchDetection, iegrCropHintsDetection, iegrWebDetection,
iegrObjectLocalization]

Example

Cursor := crHourglass;
lblSubmitting.Visible := True;
GVision := TIEGoogleVision.Create( MY_API_KEY );
try
  // Use recommended delivery size (for faster processing)
  GVision.SendImageWidth := 640;
  GVision.SendImageHeight := 480;

  GVision.RequestTypes := [iegrWebDetection, iegrSafeSearchDetection, iegrLandmarkDetection];
  GVision.ProcessImage( edtFilename.Text );

  lbxResults.Clear();

  if Length( GVision.WebDetection.bestGuessLabels ) > 0 then
    lbxResults.Items.Add( 'This image is likely to be: ' + GVision.WebDetection.bestGuessLabels[0].webLabel );

  if GVision.HasLandmarkAnnotations then
  begin
    lbxResults.Items.Add( 'This image is the landmark: ' + GVision.LandmarkAnnotations[0].description );
    lbxResults.Items.Add( 'Latitude: ' + LatLongToStr( GVision.LandmarkAnnotations[0].latitude, True ));
    lbxResults.Items.Add( 'Longitude: ' + LatLongToStr( GVision.LandmarkAnnotations[0].longitude, False ));
  end;

  lbxResults.Items.Add( format( 'Found %d matching images on the web', [ GVision.WebDetection.fullMatchingImages.Count ]));
  lbxResults.Items.AddStrings( GVision.WebDetection.fullMatchingImages );

  lbxResults.Items.Add( format( 'Found %d pages on the web containing this image', [ GVision.WebDetection.pagesWithMatchingImages.Count ]));
  lbxResults.Items.AddStrings( GVision.WebDetection.pagesWithMatchingImages );

  if GVision.SafeSearchAnnotation.adult in [ieglLikely, ieglVeryLikely] then
    lbxResults.Items.Add( 'Likely to be an ADULT image' );

  if GVision.SafeSearchAnnotation.violence in [ieglLikely, ieglVeryLikely] then
    lbxResults.Items.Add( 'Likely to be a VIOLENT image' );

finally
  Cursor := crDefault;
  lblSubmitting.Visible := False;
  GVision.Free;
