It detect document edge only on Portrait mode I'm trying to make it follow orientation any ideas ?

Sometimes the image saved get blurry because of the autofocus wasn't ready Is there anyway to make constraint for the algorithm to detect OCR image ?

after building the app without any changes the app is being stopped when capturing the picture. So i tried the sample app you provided. It did the same thing with two different devices (Galaxy S4, Galaxy Note 3) along with Pixel 2 (emulator)

If in my project set another icon(that is, not default icon), then rad studio say that "in manifest multiple error", what would he need to work remove icon from module "LiveEdgeDetection" manifest. thx for module, bro

I added :
"implementation 'com.github.adityaarora1:LiveEdgeDetection:1.0.6' "
And that doesn't work, I have this message : "Failed to resolve: com.github.adityaarora1:LiveEdgeDetection:1.0.6"

I don't want to add the entire folder in my project , It's maybe a versioning problem ?

Hi

I added library into dependency and implemented startActivityForResult as in demo but in runtime i have exception
E/vndksupport: Could not load vendor/lib/egl/libGLES_mali_v2.so from sphal namespace: dlopen failed: library "vendor/lib/egl/libGLES_mali_v2.so" not found.
Sample project working fine, don't understand why it is happens
Device: Android 8, Huawei P10

The sample app only shows "Use darker background" and stays there, any hint?
I tryed the sample app and the lib inside in my app with the same result.
I don't know if I'm missing something.

Is there a way to detect the edge when we are in bright light. Right now I am not able to do that in this demo.

Can anyone please help me with this?

Thanks in advancee.

I tried integrating the library in my project by adding the dependencies in both root gradle and app gradle file.

My config is:
compileSdk 28
minSdkVersion 21
targetSdkVersion 28

I followed the usage guide which directs to a new Intent with the camera view and I got this error:

I also tried to compile the cloned repo and run it but still got the same error.
Any inputs about this?

Thanks!

Stacktrace I don't know why this is happening
this line is causing crash

This thing is working good in phones but not at all on tab device.

Any chance you could add Open Gallery to capture save image and a share button

I've already add maven { url "https://jitpack.io" }
and implementation 'com.github.adityaarora1:LiveEdgeDetection:1.0.6' in my project.

But everytime running sync, it kept showing
Failed to resolve: com.github.adityaarora1:LiveEdgeDetection:1.0.6

I am trying to use this on Api version 28 but the camera seems not to be working. Can you suggest the possible solution?Camera is just black/white screen

is it possible to get pixel number (x,y) on every edge? i want to get pixel cordinat on every edge, do you have some advice?

Currently the edge of document is detecting on only dark background, but it ll be more useful if it can detect on any surface.

Hi
After the photo is taken it is have poor quality, how to improve the quality?
Impossible to read text

implementation 'com.github.adityaarora1:LiveEdgeDetection:1.0.6'
this doesn't work what's the latest version?

Get this error on adding dependency in gradle file.

Hi,
Can this app identify if image is blurred and also make use of autofocus?

i want use it in lanscape mode...in change in ScanActivity landscape

like
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

but it not worked proper...wht is doing change for landscape?

Execution failed for task ':app:packageDebug'.

A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
com.android.ide.common.signing.KeytoolException: Failed to read key AndroidDebugKey from store "C:\Users\yosrr.android\debug.keystore": Invalid keystore format

Hi, it gives
"Access denied finding property "vendor.camera.aux.packagelist"
then
"No implementation found for void org.opencv.imgproc.Imgproc.Canny_3"
can you help me?

Is it possible or do you have an existing setting to make that button visible? I imported your project by gradle and only the check button appears on the cropping screen unlike when I downloaded your whole git project the reject button appears when I run it.
You have a reject button here: https://github.com/adityaarora1/LiveEdgeDetection/blob/master/liveedgedetection/src/main/res/layout/activity_scan.xml

I wanted to restart scanning when the user taps on reject.

There is an error on Jitpack.io for ALL builds. But the latest one is also having the same error on the build.log file. Error is stated below:
java.lang.IllegalStateException: compileSdkVersion is not specified.

For more info look at the build log: https://jitpack.io/com/github/adityaarora1/LiveEdgeDetection/v1.1/build.log

For version 1.0.6 the issue is:

• What went wrong:
  Execution failed for task ':liveedgedetection:transformNativeLibsWithStripDebugSymbolForRelease'.

A problem occurred starting process 'command '/opt/android-sdk-linux/ndk-bundle/toolchains/mips64el-linux-android/prebuilt/linux-x86_64/bin/mips64el-linux-android-strip''

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

• Get more help at https://help.gradle.org

Hi, Is it possible to make it work with white background or something else ? where should I modify the code to make changes ?

On Android 9 the camera preview shows a white screen and not the camera feed. The doc detection still works however.

Hi, I've tried to use this library with gradle but it cant find any of the artefacts from Jitpack.io, how can I integrate it into my project?

Thanks
