The VNDetectorOption_OriginatingRequestSpecifier required option was not found" UserInfo={NSLocalizedDescription=The VNDetectorOption_OriginatingRequestSpecifier required option was not found Facing this error in only iOS15 while finding observation.

In one of the WWDC videos, the VNDetectDocumentSegmentationRequest result is described in the following way: The result of the request is a low resolution segmentation mask, where each pixel represents a confidence if that pixel is part of the detected document or not. In addition it provides the four corner points of the quadrilateral. Similarly, in the VNDetectDocumentSegmentationRequest docs there's the following statement: The result that the request generates contains the four corner points of a document’s quadrilateral and saliency mask. So the first part ("four corner points of a document’s quadrilateral") is easy - it's in the results of the request, which are in VNRectangleObservation format: let request = VNDetectDocumentSegmentationRequest { (request, error) in guard let results = request.results as? [VNRectangleObservation] else { // Failed } // Process VNRectangleObservations } but how do I obtain the "low resolution segmentation mask" / "saliency mask" for VNDetectDocumentSegmentationRequest?

I'm using Vision to conduct some OCR from a live camera feed. I've setup my VNRecognizeTextRequests as follows: let request = VNRecognizeTextRequest(completionHandler: recognizeTextCompletionHandler) request.recognitionLevel = .accurate request.usesLanguageCorrection = false And I handle the results as follows: guard let observations = request.results as? [VNRecognizedTextObservation] else { return } for observation in observations { if let recognizedText = observation.topCandidates(1).first { guard recognizedText.confidence >= self.confidenceLimit, // set to 0.5 let foundText = validateRegexPattern(text: recognizedText.string, regexPattern: self.regexPattern), let foundDecimal = Double(foundText) else { continue } } This is actually working great and yielding very accurate results, but the confidence values I'm receiving from the results are generally either 0.5 or 1.0, and rarely 0.3. I find these to be pretty nonsensical confidence values and I'm wondering if this is the intended result or some sort of bug. Conversely, using recognitionLevel = .fast yields more realistic and varied confidence values, but much less accurate results overall (even though fast is recommended for OCR from a live camera feed, I've had significantly better results using the accurate recognition level, which is why I've been using the accurate recognition level)

I'm using VNImageRequestHandler to recognize text using the camera. In my handler I'm using the topLeft, topRight, bottomLeft, bottomRight properties, which I'm scaling to the size of the canvas, to draw an outline around each text object. When I do this the Y position and Height are correct, but the Width is slightly smaller, and the X position centers the outline around the text. Any idea why this would be a different size?
