...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
I need to use face detection to finish my homework and then I searched on the Internet and I think that using a pre-trained deep learning face detector model with OpenCV's DNN module is easy and good, it works well. Where I learnt it is here: https://www.pyimagesearch.com/2018/02/26/face-detection-with-opencv-and-deep-learning/ , but I am really confused about the 4D array returned by net.forward():
...ANSWER
Answered 2021-May-02 at 15:053rd dimension helps you iterate over predictions and
in the 4th dimension, there are actual results
class_lable = int(inference_results[0, 0, i,1])
--> gives one hot encoded class label for ith box
conf = inference_results[0, 0, i, 2]
--> gives confidence of ith box prediction
TopLeftX,TopLeftY, BottomRightX, BottomRightY = inference_results[0, 0, i, 3:7]
-->gives
co-ordinates bounding boxes for resized small image
and 2nd dimension is used when the predictions are made in more than one stages, for example in YOLO the predictions are done at 3 different layers.
you can iterate over these predictions using 2nd dimension like [:,i,:,:]
QUESTION
I have this code in which mtcnn detects faces on an image, draws a red rectangle around each face and prints on the screen.
Code taken from: https://machinelearningmastery.com/how-to-perform-face-detection-with-classical-and-deep-learning-methods-in-python-with-keras/
But I want to save the image with the red boxes arround each face. So that i can do some preprocessing on it. Any help is good.

...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.

Answered 2020-Dec-06 at 14:59Chaquopy 6.3.0 isn't compatible with Android Gradle plugin version 4.1.0, and you should have received a warning about that.
See here for the compatible combinations. You should probably just upgrade to the current Chaquopy version, 9.0.0.
