I'm not sure if this is a result of null safety issues or from outdated flutter code, but after I tried upgrading this repo myself to sound null safety, when I run the camera preview, there are no predictions outputted by the model.

I have followed everything in the article / blog but when I have the camera open on the HomeView, I don't see any bounding boxes when I go near any objects, and I just see a camera preview.

Is anyone else experiencing this issue? I have not attached any logs because the issue is that I can't see anything outputted.

I have cloned and made adjustments to your code to have my model work; however, I am having issues using such a model since it requires a floating-point image to be inputted. Any ideas, how I can solve this? I will post more if needed or asked.

Hi, on the PR #4 @bazinac made the conversion work on iOS

But @tomk9 mentioned this issue:

@bazinac I tested your PR and bounding boxes are shifted on iOS.

And the probable cause:

Probably my problem with iOS is caused by this statement

I'm dealing with the same issue. anyone have any idea how to solve this issue?

Hello there,

I have been trying to implement this code for my custom model which uses YoloV3. When I get to the _outputShapes part, I get an error since the default model and mine aren't compatible.

The default model's output shape looks like this: [[1, 10, 4], [1, 10], [1, 10], [1]]

My model's output shape on the other hand, looks like this: [[1, 10647, 6]]

Here is where the problem is. I need to convert this part of code for my model.

    TensorBuffer outputLocations = TensorBufferFloat(_outputShapes[0]);

    TensorBuffer outputClasses = TensorBufferFloat(_outputShapes[1]);

    TensorBuffer outputScores = TensorBufferFloat(_outputShapes[2]);

    TensorBuffer numLocations = TensorBufferFloat(_outputShapes[3]);

What do I need to do in order for my custom model to work?

Hi,

I recently migrated the TensorFlow lite packages to the lates version and I noticed this issue.

On the camera_view.dart

cameraController = CameraController(cameras[0], ResolutionPreset.low, enableAudio: false);

cameraController = CameraController(cameras[0], ResolutionPreset.medium, enableAudio: false);

cameraController = CameraController(cameras[0], ResolutionPreset.high, enableAudio: false);

The updated pubspec.yaml

  camera: ^0.8.1+3
  tflite_flutter: ^0.9.0
  tflite_flutter_helper: ^0.3.0
  image: ^3.0.8
  path_provider: ^2.0.1
  image_picker: ^0.7.3

That is nice example, but it does not run on iOS as ImageUtils.convertYUV420ToImage is failing with

Camera preview starts, but it seems that classifier is not obtaining any images due to this...

EDIT: Ok, I have found that this is caused by the fact that in iOS, cameraImage.format is bgra8888.
and android cameraImage.format, it is yuv420. I will try to provide code that would handle images based on what platform it runs on and post PR.

Sorry don't know what to label this issue as. I think it's more likely an error my side than something wrong with the package. Any help will be appreciated (I'm new to TensorFlow in general). Also thanks for the amazing package!

I'm trying to use this model: https://tfhub.dev/intel/lite-model/midas/v2_1_small/1/lite/1
It computes depth from an image.

And as far as I can see I'm doing all the necessary steps. I copied the code from your image classification example, and also double checked with the Android example provided in the link above (and as far as I can see I'm doing the same steps).

I'm using the tflite flutter helper package.

I'm getting a failed precondition in Quiver at the following point (when I call interpreter.run):

checkState(tfLiteTensorCopyFromBuffer(_tensor, ptr.cast(), bytes.length) ==
        TfLiteStatus.ok);

Something that also has me confused is that interpreter.getInputTensor(0).type returns TfLiteType.float32, but I expected this to be uint8 from the model description.

Are there any plans for a null safety update?

Hi,

I would like to know how to run detection on an image fetched from the gallery.

PS: Sorry I am new to flutter

I am currently working on an object detection app, but our models are yolo v3 and yolo v4, and so far I haven't found anything that could help me, does this example cover these models?

Hi @am15h Thanks for your job!
I was able to test your app and find out some error - Uninitialized CameraController. Can you explain to me what is wrong?
Thanks!

Error: The method 'File.create' has fewer named arguments than those of overridden method 'File.create'.

I have seen that it wrote "If you need to test a specific image, you can get a file path where you can put the image. Look at getExternalStorageDirectory() from path_provider package;".

I'm new in flutter, so it quite difficult for me to know how to revise it. Does anyone know it? Or where is the part that I need to revise?

I will be very grateful for your help.

if you getting this error Flutter Build Error: Process 'command 'E:\Flutter Apps\flutter\bin\flutter.bat'' finished with non-zero exit value 1

then do this :-
I had the same problem after this command flutter upgrade and upgrading from V 1.22 to V 1.27.
Exactly what I did, I went to pubspec.yaml then pub-get & pub-upgrde I found there's many outdated packages then I tried pub-outdated and the AS failed to upgrade it, the it's suggests to me to run this command flutter pub upgrade --major-versions and I saw that it's successfully downloaded and installed outdated packages, Then I do Invalided Caches & restarted AS because I found it's cached about 5GB on C partition, and finally I run the app normally again without any problems.

after this run flutter run or flutter run --no-sound-null-safety

Hi,
Are you guys planning to update this example for null safety?

I gonna to do a project with yolov4-tiny, I just put my file on but it's not work.
Is there any thing i need to modify?
And this is the first problem as I put my file in the project. Is there any way to solve it?

Thanks a lot for help!!

I am currently running a tflite Mediapipe model which outputs a 3D bounding box. So I would like to know is there a way to drawing the 3D bounding box in my Flutter App as we are able to draw the 2D bounding box.

This is the current OutputTensor am receiving from my tflite model and I want use to draw the 3D bounding box

flutter: [120.87956237792969, 115.73860168457031, 138.97604370117188, 187.78915405273438, 137.4835205078125, 84.2886734008789, 151.32508850097656, 165.74168395996094, 146.28330993652344, 51.38185501098633, 95.4119873046875, 181.07603454589844, 97.72759246826172, 77.48689270019531, 100.90084838867188, 155.7063751220703, 101.90467071533203, 40.651939392089844]

do you have this project in null safety

Actually i dont know what's happening, the variable index, in line 45 of image_utils.dart, increase and stop inference.

Flutter Version: 2.5.1
Pixel 5 android-x86 emulator

Ran this project successfully and updated to null safety here:

• https://github.com/blakewood84/flutter-object-recognition

To add the TensorFlowLiteC.framework successfully and avoid the compile error, download the .zip file, unpack it. Then move this folder (TensorFlowLiteC.framework) into your pub.dev cache folder: ~/pub-cache/hosted/pub.dev/tflite_flutter-0.9.0/ios/ (macOS).

Run flutter clean && flutter pub get,
then pod install in your ios folder.

This should work 😎

Just FYI, I only ran the project for iOS, so if you're wanting to add Android just flutter create . --platforms=android inside the root of the project folder.

The syntax of info.plist is incorrect and the build fails.

I changed some image converting places and tryed to run on ios. On android everything works fine, and on ios the line _sendPort = await _receivePort.first; never ends. It stops on that await place. Can you please help me with it?

Is there a way to record the camera video in parallel with detections running ? basically i would like to use image stream with recoding video.

Hi, this is not an app issue. But maybe anyone can provide me with some ideas in how to achieve my goal.

I'm using this project as a base for another project I've been working for a couple of months. But I'm still struggling with the Isolate handling.

The basic idea is to detect and object, then take a "screenshot" and then this image will be compared with predefined set of images.

For example: The model detect a "ball" the app take a screenshot and then using a comparison algorithm it will return the type of ball (baseball, golf, football). Once the comparison process is completed it will navigate to a "result screen" where the app should display the type of ball found.

I'm facing two problems here.

1. While I'm 'waiting' for the comparison algorithm to complete the object detection is still running in the background and detecting more objects.

I modified the recognition.dart class and I added a new attribute

// Cropped image is where the object detected is located (like a screenshot)
Image cropedImage;

Then on my home_view.dart, on the resultCallback function

  void resultsCallback(List<Recognition> results) {

    setState(() {
      this.results = results;
    });

    if (results.isNotEmpty) {
      comparisonAlgorithm(results);
      });

    }

  comparisonAlgorithm(List<Recognition> results) async {
    setState(() {
      // I want to use this variable to display a loading image or something like that...
      _ComparisonStatus = true;
      _imageFoundStatus = false;
    });

    // Comparison is a custom class where I will store the result of the algorithm comparison.
    Comparison comparison; 
    Map ComparisonResult = {};

//    for (var x = 0; x < results.length; x++) {
    comparison = Comparison(0, results[0].cropedImage);
    // Here the app should await and do not make any object detection until the process has been completed.
    ComparisonResult = await comparison.algorithmGeneration;
//    }

    // One or more images has been found
    if (ssimComparisonResult != null) {
      setState(() {
       // comparison process has been completed, so we don't need to display the "loading" anymore
        _ComparisonStatus = false;
       // boolean used to navigate to the success screen
        _imageFound = true;
      });
    }

    if (_imageFound) {
      _openSuccess();
    }
  }

2. When I navigate to the "success" screen the object detection is still running in the background and detecting more objects, I tried to implement the function pause

// File isolate_utils.dart


  void pause() async {
    _isolate.pause();
  }

  static void entryPoint(SendPort sendPort) async {
    final port = ReceivePort();
    sendPort.send(port.sendPort);

    await for (final IsolateData isolateData in port) {
      if (isolateData != null) {
        Classifier classifier = Classifier(
            interpreter:
                Interpreter.fromAddress(isolateData.interpreterAddress),
            labels: isolateData.labels);
        imageLib.Image image =
            ImageUtils.convertCameraImage(isolateData.cameraImage);
        if (Platform.isAndroid) {
          image = imageLib.copyRotate(image, 90);
        }
        Map<String, dynamic> results = classifier.predict(image);
        isolateData.responsePort.send(results);

      }
    }
  }

and on the file
//camera_view.dart

      Map<String, dynamic> inferenceResults = await inference(isolateData);

//      isolateUtils.pause();

      var uiThreadInferenceElapsedTime =
          DateTime.now().millisecondsSinceEpoch - uiThreadTimeStart;

      // pass results to HomeView
      widget.resultsCallback(inferenceResults["recognitions"]);

      // pass stats to HomeView
      widget.statsCallback((inferenceResults["stats"] as Stats)
        ..totalElapsedTime = uiThreadInferenceElapsedTime);

      // set predicting to false to allow new frames
      setState(() {
        predicting = false;
        isolateUtils.pause();
      });
    }
  }

But I don't know how to resume the Isolate when I click on the button "back" to detect another object, I have to close the app and start the app again in order to make another object detection.

Can anyone please explain how the output tensors are formed? I am currently working on detecting multiple objects on an image ( I am using a yolov5 model). I believe the input tensor will be equal to the shape of the image ( for example, [1, 416, 416, 3]), however, i couldn't really understand how the output tensors should look like. Normally, I should expect the coordinates of each detected bounding box.

Thank you for your excellent work，I wanna build an app to detect traffic sign.
How can I train my custom model and deploy it directly on this app.
