HDR Merge possible bug ?
I try in Python the example of the "memorial". There are two possibilities to call the merge:
1. Calibrate the response on images and times and use to use it for the merge
2. Do the merge directly on images and times
I do not get the same result. The image created by 2 is correct and the image created by 2 bad
Do I make some mistake ?
Regards
calibrate = cv.createCalibrateDebevec()
response = calibrate.process(images, times)
merge_debevec = cv.createMergeDebevec()
#hdr = merge_debevec.process(images, times, response) #Bad
hdr = merge_debevec.process(images, times) #Good
tonemap = cv.createTonemapReinhard()
ldr = tonemap.process(hdr)
cv.imwrite('ldr.png', ldr * 255)
cv.imwrite('hdr.hdr', hdr)

ArUco detection x-y axis values are extremely different
Hello. My problem is that I am trying to detect aruco markers. I need coordinates aruco centered so I implemented [this part of the code](https://github.com/tizianofiorenzani/how_do_drones_work/blob/6433bdac938fcb91192097f7a82e43ba9b33f530/opencv/lib_aruco_pose.py#L165) to c++ and checked.

When I check 2 consecutive frames, we can see that even though there are almost no difference in images we get 30 centimeters of difference:
I calibrated well enough and I am sure of it because Z axis is very good. Results for Z axis very fine( in terms of world coordinates) but X and Y axis values are changing very different.
Has anyone got the same problem? What could be the problem ?
Any idea is helpful. For the code you can check the permalink above.
PS: Numbers in the image-> "Frame number: X Y"
Edit: Frame 110 and 121 below. Dict name -> cv::aruco::DICT_6X6_100

How to increase TOTAL_MEMORY for OpenCV JS?
I am using **opencv.js **. After some time working (about 1 min) it crashes and in the browser console, I see the following.
Uncaught abort("Cannot enlarge memory arrays. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value 2147221504, (2) compile with -s ALLOW_MEMORY_GROWTH=1 which allows increasing the size at runtime, or (3) if you want malloc to return NULL (0) instead of this abort, compile with -s ABORTING_MALLOC=0 "). Build with -s ASSERTIONS=1 for more info.
How can I increase TOTAL_MEMORY or set **ALLOW_MEMORY_GROWTH = 1** for Opencv JS
I built opencv.js as it's described [here](https://docs.opencv.org/3.4/d4/da1/tutorial_js_setup.html)

OpenCV on Android crash if resolution of image for laplace is too small
Hello!
I am working on a blur detection with OpenCV for Android and used following code found here which seemed to work correctly:
http://answers.opencv.org/question/111798/android-blur-image-detection-with-opencv-results-into-heavy-apk-size/
Now, my problem is that it crashs, if the resolution of the image is too small. In the sample code the transformed image gets resized to 2000*2000, but only if it is bigger than that.
It happens here:
> Imgproc.Laplacian(matImageGrey,> laplacianImage, CvType.CV_8U);
I have tested it serveral times and no crash with big images!
No crash image resolution: 1048 * 1048
Crash with resolution: 511*511
Does anybody now why this happens? It seems that there is a minimum image resolution size needed, but I can not find any info in the OpenCV documentation or in the internet.
Thanks!

BGR to Lab conversion issue
Hi all,
I wrote the code for RGB to lab color conversion for cuda by using mathematical formulae which are mentioned in the OpenCV documentation but when I compare the l ,a ,b values from the cvColor function and my cuda function, there is a difference of 5 to 15. It will be great, if you suggest me the way.
__global__ void kRgb2CIELab(PtrStepSz src, PtrStepSz dst, int width, int height) {
int px = blockIdx.x * blockDim.x + threadIdx.x;
int py = blockIdx.y * blockDim.y + threadIdx.y;
if (px < width && py < height)
{
uchar3 nPixel = src(py, px);
float blue = (float)nPixel.x / 255.0;
float green = (float)nPixel.y / 255.0;
float red = (float)nPixel.z / 255.0;
float x = red * 0.412453 + green * 0.357580 + blue * 0.180423;
float y = red * 0.212671 + green * 0.715160 + blue * 0.072169;
float z = red * 0.019334 + green * 0.119193 + blue * 0.950227;
x /= 0.950456;
float y3 = exp(log(y) / 3.0);
z /= 1.088754;
float l, a, b;
x = x > 0.008856 ? exp(log(x) / 3.0) : (7.787 * x + 16/116);

Image Classification
I am trying to classify two kinds of images as follows:
(1)
(2)
classes can be called unscrewable/screwable. The screwable ones(1) are the ones with a slot on them, in addition to the hole, whereas the unscrewable ones only contain a hole.
There are two ways of solving this problem.
1. Train a network.
2. Use edge information.
I tried to use sobel derivates and Canny but one can't implement something that works for all, I mean, anything that is threshold-dependent is not so reliable, I try to avoid using such methods, therefore. What works for these two images, does not work for more and etc. Perhaps sobel derivates weren't the best choice for this type, I don't know. Hence, my question.
I was curious if anyone here try to achieve something similar. The difference between these two classes are really little, and I wonder if it makes sense to use purely traditional image processing techniques found in OpenCV or to deploy a neural network. I suspect haar classifier wouldn't be able to tackle this either.
What do you think?

Taking 5 pictures in difference of 400 ms
Hi all,
I'm new in opencv for android and I'm trying to take 5 pictures every 400 ms and save them.
Here is what I did:
> btn_ok = findViewById(R.id.btn_ok);
btn_ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(TAG, "on button click");
for(int i =0; i<5;i++) {
try {
TimeUnit.MILLISECONDS.sleep(400);
} catch (InterruptedException e) {
Log.i(TAG, "sleep exception");
e.printStackTrace();
}
Date sdf = new Date();
Log.i(TAG, "loop number: "+i);
String currentDateandTime = sdf.toString();
String fileName = Environment.getExternalStorageDirectory().getPath() +
"/sample_" + currentDateandTime +"__"+ i + ".jpeg";
cameraBridgeViewBase.takePicture(fileName);
}
}
also:
> public class myJavaCameraView extends JavaCameraView implements android.hardware.Camera.PictureCallback {
static{
System.loadLibrary("native-lib");
}
private static final String TAG = "Opencv";
private String mPictureFilename;
public myJavaCameraView(Context context, AttributeSet attrs ){
super(context,attrs);
}
public void takePicture(final String fileName)
{
Log.i(TAG,"Taking picture");
this.mPictureFilename = fileName;
mCamera.setPreviewCallback(null);
mCamera.takePicture(null,null,this);
}
@Override
public void onPictureTaken(byte[] data, Camera camera) {
Log.i(TAG,"saving bit,ap to file");
// the camera preview automatically stopped so we start it again
mCamera.startPreview();
mCamera.setPreviewCallback(this);
// write image to file
try {
FileOutputStream fos = new FileOutputStream(mPictureFilename);
fos.write(data);
fos.close();
}
catch (java.io.IOException e)
{
Log.e("PictureDemo", "exception in photocallback",e);
}
}
Looking at the log files I can see that after the fifth call to takePicture the OnPictureTaken get called 3/4 times so I guess it been stored in a queue. Someone know how can I overcome this problem? I need OnPictureTaken to be called right after every call for takePicture.

Dense Optical flow from sparse motion vectors
Hi community,
I created a sparse optical flow (vector field) from KLT but I want to extend this to a dense optical flow (like Gunnar Farnback is doing). I found the function cv::ximgproc::EdgeAwareInterpolator() but this is very slow and without any acceleration. Could someone give me a hint?

Linking prebuilt opencv static library in Android.mk
Hi
I am trying to link prebuilt external/opencv3 libopencv_core.a in the Android tree to my project that's also in the tree. I get the following error
ninja: error: 'out/target/product/neo/obj/STATIC_LIBRARIES/libopencv_core_prebuilt_intermediates/export_includes', needed by 'out/target/product/neo/obj/STATIC_LIBRARIES/libNV_intermediates/import_includes', missing and no known rule to make it
I am able to link to libopencv_core when Android builds it, but I need to link to opencv3 built with opencl created using the following make.
cd /hdd/NEO8/external/opencv3/platforms
./scripts/cmake_android_arm.sh -DANDROID_ABI=arm64-v8a -DANDROID_NATIVE_API_LEVEL=android-23 -DWITH_OPENCL=yes -DWITH_CUDA=no
cd build_android_arm
make -j8
OpenCV static libraries are created in the lib/arm64-v8a directory.
My project is all native code (c++) with no jni or Java.
The tree structure is:
hdd/NEO8/
external/opencv3 (this is where I build the libopencv_core.a)
device/my_app (this is where my Android.mk is)
The external/opencv3 code is v3.0 downloaded from Google.
I'd attach the Android.mk but this forum only allows image attachments. Below is how I'm adding the prebuilt to the Android.mk
include $(CLEAR_VARS)
PREBUILT_PATH := /hdd/NEO8/external/opencv3/platforms/build_android_arm/lib/arm64-v8a
PREBUILT_INCLUDE_PATH := /hdd/NEO8/external/opencv3
LOCAL_EXPORT_C_INCLUDE_DIRS := \
$(PREBUILT_INCLUDE_PATH) \
$(PREBUILT_INCLUDE_PATH)/modules/core/include \
$(PREBUILT_INCLUDE_PATH)/opencv2 \
$(PREBUILT_INCLUDE_PATH)/modules/hal/include
LOCAL_MODULE := libopencv_core_prebuilt
LOCAL_SRC_FILES := $(PREBUILT_PATH)/libopencv_core.a
include $(PREBUILT_STATIC_LIBRARY)
The LOCAL_EXPORT_C_INCLUDE_DIRS is the same as what I use when I link to Android built opencv3.
I can tell that the Android build process is finding the libopencv_core.a file because when I change the static library name to something bogus, i.e.
LOCAL_SRC_FILES := $(PREBUILT_PATH)/libopencv_core_bogusName.a
the linker says it can't find **libopencv_core_bogusName.a**.
Is there a way to get more information out of the Android build info like a verbose=true setting?
Any ideas on what I can try would be greatly appreciated.
This is the entire Android.mk

[Opencv4] Settings.write not working Incorrect element name {; should start with a letter or '_' in function 'operator
I am just trying to perform chessboard camera calibration based on [camera calibration](https://github.com/opencv/opencv/blob/master/samples/cpp/tutorial_code/calib3d/camera_calibration/camera_calibration.cpp) sample.
So I am trying to let my QT app save the calibrations settings using Settings class as defined int above code. There is a function for this which is Settings.write but when I call as below it gives me this error:
void saveCalibrationSettings(const Settings currentSettings){
FileStorage fs = FileStorage(Ui::calibrationFilename, FileStorage::WRITE);
currentSettings.write(fs);
fs.release();
}
the error is as below:
Gtk-Message: 02:56:21.529: Failed to load module "canberra-gtk-module"
Input does not exist: images/CameraCalibration/VID5/VID5.xmlterminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(4.0.1) /home/mike/opencv-4.0.1/modules/core/src/persistence.cpp:1995: error: (-2:Unspecified error) Incorrect element name {; should start with a letter or '_' in function 'operator<<'
I just need my QT GUI application to be able to save a Settings object into a file so that it could follow the correct calibration settings format which then can be fed to the calibration process.
