Is there a framework that allows for classic image processing operations in real-time from incoming imagery from the front-facing cameras before they are displayed on the OLED screens? Things like spatial filtering, histogram equalization, and image warping. I saw the documentation for the Vision framework, but it seems to address high-level tasks, like object and recognition. Thank you!

Why iOS 17's lift subject returns jagged edge and low resolution result image ? The output quality is totally different from iOS16. Does this just occur to beta version? or will it be the same in real iOS17 release version ?

Hi, Can VisionPro see outside and let us take a picture from code/iOS/Programming? Eg: like we used to have camera permission on iPad/iPhone to have access to device camera. Thank you

How can I achieve full control over Vision Pro's display and effectively render a 2D graph plot on it? I would appreciate guidance on the necessary steps or code snippets. P.s. As per Apple documentation For a more immersive experience, an app can open a dedicated Full Space where only that app’s content will appear. This still does not fulfill the 'flat bounded 2D' requirement as the Spaces provide an unbounded 3D immersive view.

First of all this vision api is amazing. the OCR is very accurate. I've been looking to multiprocess using the vision API. I have about 2 million PDFs I want to OCR, and I want to run multiple threads/run parallel processing to OCR each. I tried pyobjc but it does not work so well. Any suggestions on tackling this problem?

In VisionOS is it possible to detect when a user is touching a physical surface in the real world and also to project 2D graphics on that surface? So imagine a windowless 2D app that is projected onto a surface, essentially turning a physical wall, table, etc. into a giant touchscreen? So kinda like this: https://appleinsider.com/articles/23/06/23/vision-pro-will-turn-any-surface-into-a-display-with-touch-control But I want every surface in the room to be touchable and be able to display 2D graphics on the face of that surface and not floating in space. So essentially turning every physical surface in the room into a UIView. Thanks!

Hello, I'm doing a iOS app and I'm trying to find a way to extract programmatically a person from his identity picture (and to leave behind the background) I'm watching WWDC "Lift subjects from images in your app" video (a really cool feature) and i'm wondering if this feature would be possible programmatically, without the need of a human person interaction. Thank you.

Using VNDocumentCameraViewController, if the document is automatically scanned, it cannot be obtained in the func documentCameraViewController (_ controller: VNDocumentCameraViewController, didFinishWith scan: VNDocumentCameraScan) {}. If manual photography is used, data can be obtained May I ask how to solve it?

I trying to scan credit card but i am getting some issue with printed( Pressed ) number on card and some dark background with dark card numbers as well not scanning. Please help me to smooth scan for every cards. Thanks.

var accessibilityComponent = AccessibilityComponent() accessibilityComponent.isAccessibilityElement = true accessibilityComponent.traits = [.button, .playsSound] accessibilityComponent.label = "Cloud" accessibilityComponent.value = "Grumpy" cloud.components[AccessibilityComponent.self] = accessibilityComponent // ... var isHappy: Bool { didSet { cloudEntities[id].accessibilityValue = isHappy ? "Happy" : "Grumpy" } }

I notice that some WWDC sessions have a code tab (in addition to Overview and Transcript) but this session 10176 does not. I tried what code I could see on the video but it's obviously not a complete project. It would help if the authors of the Session 10176 video could add the code to the session.

I have a live text implementation on the following LiveTextImageView. However, after the view loads and the analyze code is run, none of the delegate methods fire when I interact with the Live View. Selecting text does not fire the textSelectionDidChange method, nor does highlightSelectedItemsDidChange fire when the live text button in the bottom right is pressed. I tried a few different implementations, including an approach where the delegate was defined on a separate class. I am running this on a iPhone 12 Pro I recently updated to 17.0.3. My goal is to be able to provide additional options to the user beyond the default live-text overlay options, after identifying when they have finished selecting text. // // LiveTextImageView.swift // import UIKit import SwiftUI import VisionKit class ImageAnalyzerWrapper { static let shared = ImageAnalyzer() private init() { } } struct LiveTextImageViewRepresentable: UIViewRepresentable { var image: UIImage func makeUIView(context: Context) -> LiveTextImageView { return LiveTextImageView(image: image) } func updateUIView(_ uiView: LiveTextImageView, context: Context) { } } class LiveTextImageView: UIImageView, ImageAnalysisInteractionDelegate, UIGestureRecognizerDelegate { var capturedSelectedText: String? let analyzer = ImageAnalyzerWrapper.shared let interaction = ImageAnalysisInteraction() init(image: UIImage) { super.init(frame: .zero) self.image = image let photoWrapper = PhotoWrapper(rawPhoto: image) let resizedPhoto = photoWrapper.viewportWidthCroppedPhoto(padding: 40) self.image = resizedPhoto self.contentMode = .scaleAspectFit self.addInteraction(interaction) interaction.preferredInteractionTypes = [] interaction.analysis = nil analyzeImage() } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } func analyzeImage() { if let image = self.image { Task { let configuration = ImageAnalyzer.Configuration([.text]) do { let analysis = try await analyzer.analyze(image, configuration: configuration) self.addInteraction(interaction) interaction.delegate = self interaction.analysis = analysis interaction.preferredInteractionTypes = .textSelection } catch { print("Error in live image handling") } } } } func interaction( _ interaction: ImageAnalysisInteraction, highlightSelectedItemsDidChange highlightSelectedItems: Bool) async { print("Highlighted items changed") } func interaction(_ interaction: ImageAnalysisInteraction, shouldBeginAt point: CGPoint, for interactionType: ImageAnalysisInteraction.InteractionTypes) async -> Bool { return interaction.hasInteractiveItem(at: point) || interaction.hasActiveTextSelection } func textSelectionDidChange(_ interaction: ImageAnalysisInteraction) async { print("Changed!") if #available(iOS 17.0, *) { capturedSelectedText = interaction.text print(capturedSelectedText ?? "") } } }

I use DataScannerViewController to scan barcode and text recognize, and then get the AVCaptureDevice to use torch on/off, but DataScannerViewController will stop scanning. DataScannerViewController has no related API to get AVCaptureDevice to use torch. Expected: Could use AVCaptureDevice to turn on/off torch, at the same time DataScannerViewController could scan.

I was looking for IP camera which is not very expensive. The key point is I should be able to convert its frames to CMSampleBuffer I would like to use images to make some basic analysis using Vision. So far I could not find any IP camera manufacturer supports SDK for Swift and iOS for this kind of study.

Hi guys, has any individual develper received Vision Pro dev kit or is it just aimed at big companies? Basically I would like to start with one or 2 of my apps that I removed from the store already, just to get familiar with VisionOS platform and gain knowledge and skills on a small, but real project. After that I would like to use the Dev kit on another project. I work on a contract for mutlinational communication company on a pilot project in a small country and extending that project to VisionOS might be very interesting introduction of this new platform and could excite users utilizing their services. However I cannot quite reveal to Apple details for reasons of confidentiality. After completing that contract (or during that if I manage) I would like to start working on a great idea I do have for Vision Pro (as many of you do). Is it worth applying for Dev kit as an individual dev? I have read some posts, that guys were rejected. Is is better to start in simulator and just wait for actual hardware to show up in App Store? I would prefer to just get the device, rather than start working with the device that I may need to return in the middle of unfinished project. Any info on when pre-orders might be possible? Any idea what Mac specs are for developing for VisionOS - escpecially for 3D scenes. Just got Macbook Pro M3 Max with 96GB RAM, I'm thinknig if I should have maxed out the config. Anybody using that config with Vision Pro Dev kit? Thanks.

Is it possible to use ImageAnalysisInteraction as discussed in WWDC23 "Lift subjects from images in your app" using Objective-C?
