TIEGoogleVision.WebDetection

Declaration

property WebDetection: TIEGWebDetection;

Description

Returns the result array for Web Entities and Pages (from a iegrWebDetection request).
WEB_DETECTION detects references and related web information for an image, including:
◼Best guess label: A best guess as to the topic of the requested image inferred from similar images on the Internet
◼Inferred entities (labels/descriptions) from similar images on the Web
◼Full matching images: A list of URLs for fully matching images of any size on the Internet
◼Partial matching images: A list of URLs for images that share key-point features, such as a cropped version of the original image
◼Pages with matching images: A list of Webpages with an image that matches one of the above rules
◼Visually similar images: A list of URLs for images that share some features with the original image

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
