QUESTION
I'm using the Pose Detection, and I tried to use the facial landmarks to calculate the 3d head position and rotation. But as said in MLKit's PoseDetection documentation, the z position for the face landmarks should be ignored.
So I would like to know if there is another way to obtain the head rotation and position from the data that the Pose Detection gives us.
...ANSWER
Answered 2021-Jun-09 at 16:29Head rotation is not available in the Pose detection feature today, but you can get the head rotation info from ML Kit face detection APIs. See https://developers.google.com/android/reference/com/google/mlkit/vision/face/Face#public-method-summary, which provides HeadEulerAngleX/Y/Z()

...ANSWER
Answered 2021-May-18 at 17:05you may have an existing firebase dependency that pulls in com.google.firebase:firebase-common:16.0.3 which is not compatible with the mlkit APIs. You can resolve this by using the latest firebase BOM which specifies the latest versions for all firebase SDKs:
// Import the BoM for the Firebase platform implementation platform('com.google.firebase:firebase-bom:28.0.1')
// OR, just explicitly pull in the latest firebase-common dependency in your project: implementation 'com.google.firebase.firebase-common-20.0.0'
QUESTION
Summary/TL;DR: ML Object Detection application is unable to detect objects because images aren't being acquired by analyze()
method.
I'm currently working on a mobile application using CameraX and Google ML Kit written in Java. The purpose of the application is to detect objects with a real time camera preview. I implemented ML Kit using this guide aptly titled "Detect and track objects with ML Kit on Android" (base model option) to detect objects in successive frames within the application.
However, upon running the application, it launches on my device and the camera preview continues to work but the application does not carry out its intended effect of actually detecting objects and displaying it on my screen. To attempt to resolve this, I had found this StackOverflow answer that very closely resembles this issue. To my dismay, the user had built their application using a custom model (tflite). This differs from mine as I am using the base model. According to my research, this uses the ML Kit's on-device's object detection. The code being applied is restricted to what is present within the aforementioned documentation. Since my IDE (Android Studio) does not display any errors within the syntax, I am unsure as to why any object detection does not appear to be present on my application. Displayed below is the necessary code that had been used:
CODE ...ANSWER
Answered 2021-Apr-02 at 18:33As mentioned in the other StackOverflow question you linked, you need to bind the analysis use case to make it work.
One tip to help debug this is that you can add some Log.d(..) in onSuccess to check the size of the returned object list and in onFailure to print out the exception. Then when running, you could use adb logcat or the AS log tab to check the info to make sure things are running.
Another improvement you can make is that, you don't need to create a new object detector each frame. You can create one out side the analyze method and reuse it.

QUESTION
There is this situation where I am trying to use MLKit inside Unity. Naturally I make an Android plugin. Here are the Gradle dependencies:
...ANSWER
Answered 2021-Apr-16 at 19:41As the error message suggests, the same stuff seams to be around in two separate dependencies: once in ":PoseDetector-release:" and once in ":androidx.camera.camera-camera2-1.1.0-alpha02:"
I have run in this issue before, and was able to solve it. Sometimes it takes longer to find out which dependencies to remove.
The solution to this error is to remove one of the duplicate dependencies, in my case I believe it was removing the android plugin folder of some SDK in my Project's Assets Folder, due to the fact that the same dependency was already included by some package I downloaded and imported via the unity package manager.
The two cases I can think of, where my answer is garbage are:
The collision is NOT due to collision between same dependencies, but just between namespaces
You can not remove neither of the two dependencies because they only overlap, but BOTH each contain MORE stuff you need, which is NOT already included in the other one

Device: Huawei P40 Lite E dependencies:
...ANSWER
Answered 2021-Apr-08 at 21:37Simultaneous ImageCapture in YUV and ImageAnalysis in YUV isn't supported on all camera devices; if you switch the ImageCapture to JPEG you should be fine on all devices (if you want details, you can look at the tables in the underlying camera2 API's session creation). LIMITED-level camera devices only support 3 outputs if one of them is JPEG. FULL-level devices should support it, though.
That's why setBufferFormat is not part of the CameraX public API - using it easily pushes you out of the set of outputs that are commonly supported by camera devices.
QUESTION
I have a Google MLKit model for labeling an Image after capturing the image, but everytime I tried to process the Image, it always give me this error:
label process error:: Pipeline failed to fully start: Calculator::Open() for node "ClassifierClientCalculator" failed: #vk The TFLite Model Metadata must not contain label maps when
text_label_map_file
is used.
Here's my MLKit image labeler configuration code (this code is based on MLKit's documentation):
...ANSWER
Answered 2021-Apr-06 at 18:13Here's my understanding based on the error message:
Given you are using the LocalModel(manifestPath: manifestPath)
API, it is expecting a legacy TFLite model format where the label map is provided through a separate text file and the model.tflite
itself does not contain the label map. That's why your file before your model update works.
To use your updated model.tflite
(which seems to contain the lab map inside its metadata), I think you can try the following to use the model.tflite
file directly with the custom models API without going through the filename.json
manifest:

...ANSWER
Answered 2021-Mar-31 at 16:52inputImage.getByteBuffer() is an internal method which is not designed for public usage. This method will only return when you use a bytebuffer or byte array to construct the image. If you need to use a bytebuffer from your android media image, you will need to do the conversion on your own.
Also, we made some changes to Firebase ML Kit to better distinguish the on-device APIs from cloud based APIs. "ML Kit"(without firebase branding) contains all the on-device APIs. Here's the migration guide from firebase mlkit to mlkit. All further improvements and new APIs will be released only with the new ML Kit.

Install MLKit
You can use MLKit like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the MLKit component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
