Launch Camera with OpenCV in Android Studio & Process Frames | Android Deep Learning with OpenCV #3

I copied your code and when I run the app it always pop the message "There's a problem, yo!", what's going wrong? Is it possible that some changes from dependencies migrating to AndroidX affecting the whole thing?

I did every thing step by step why it does not work🥲

So much efforts you give to make the whole tutorials. Salute !! 👍👍

Camera is black :(

starting from this point. Do you know some functions to convert each frame to YUV mat format and only keep the Y?
and some function to decode a stripes message?
like black and white stripes and convert to bits: black stripe bit 0 and white stripe bit 1.

Thanks for the video, was helpful for me!

Can you tell me how to add a code to process an image(face) using open CV?

Great Job, thank you!
However for this line
cameraBridgeViewBase = (JavaCameraView)findViewById(R.id.CameraView);
gettting error:
"Inconvertible types; cannot cast 'android.view.View' to 'org.opencv.android.JavaCameraView'"
Any ideas please?

When I want to add the (org.opencv..Java.. Etc)
In the xml activity, there is a error, what is the problem?

Thanks for this video, I want to ask how could I change the size of the frame (cause I need to reduce the frame resolution) on the onCameraFrame() method?

Super cool Android series! take your like, good sir!

Hi Ivan, you have done a great job by uploading this series of OpenCV. I am doing my Master thesis project in OpenCV Android and I have to implement those algorithms which are not yet implemented for android so all these videos will help me, thanks a lot!!! I am currently executing this code, all is working fine, just I am getting inverse orientation. Android Studio and OpenCV versions are latest and thus in the latest Android Studio build, android:screenOrientation="fullSensor" is used instead of android:screenOrientation="landscape", any help will be appreciated!!

Brother my android studio doesnot display hints for methods , example when i type implements CameraBrid .. it doesnot pop up remaining text :)

Hi Ivan I've followed every step of your tutorial and the App is working fine so far, thanks a lot. This is when a 51 years old guy learns from a 3 times younger guy. Big hug from Argentina!!!
