Hi ,I am new to OpenCV.
I am trying to install opencv-python for Windows. I literally followed instruction from this link: https://docs.opencv.org/3.2.0/d5/de5/tutorial_py_setup_in_windows.html
When I execute "import cv2" from my python IDLE I got the following error message
ImportError:DLL lload failed: %1 is not a valid Win32 application
Could anybody help?
Thanks,

Assert error when trying to apply ROI to BackgroundSubtractorMOG2
Hi,
Ive stuck in a problem that I cannot apply a ROI to the BackgroundSubtractorMOG2. if i put whole image or my ROI started from corner (0,0) everything is ok, but when I put the part of the image Ive got the assertionfailed error. Im using opencv 3.4.0 with python 2.7 Here is my code:
numOfROIs = len(ROIs)
for i in range(0,numOfROIs):
backSubArray.append(cv2.createBackgroundSubtractorMOG2())
roi_id = 0
for (x_l, y_u, x_r, y_d) in ROIs:
print x_l, x_r, y_u, y_d
cropped_img = img[y_u:y_d,x_r:x_l].copy()
diff_gray_loc = backSubArray[roi_id].apply(cropped_img)
#diff_gray |= diff_gray_loc
roi_id+=1

Error with stereocalibrate function in python

I have a problem with the stereocalibrate function in python although calibrateCamera works well with the same structure of data (e.g. list of numpy arrays). The error is a system error : " new style getargs format but argument is not a tuple". My version of python is 3.5 and OpenCV is 3.2.0.dev.

ANN classification error
Good day everyone, thanks for taking the time to look into my question.
I've started implementing an ANN classification based on OpenCV but I have this error:

I am trying to build opencv-3.4.1-vc14_vc15 in my windows 10 using cmake-3.10.2-win64-x64. First of all I tried using CMake to configure and generate the new_build files(using codeblocks minGW makefile). I only checked the BUILD_opencv_world option as I saw in a tutorial. I think it did it without errors. Then I opened the OpenCV.cbp file within my codeblocks 17.02 and build it.
but I got this error:

get errors while execute forward step with torch model
I have trained a torch model and it works well in torch/lua. And after I import it into opencv and excute the forward step, the following error occured: `"Incorrect size of input array in cv::dnn::ConcatLayerImpl::getMemoryShapes " file : dnn/src/layers/concat_layer.cpp line 94.` All codes can be found in [here](https://github.com/chenbohua3/faceAlignment) fan2.lua is the file to create the torch model and main.cpp is the file to load the model and execute the forward step.

open_cv core build fails
Hi,
I am trying to build open cv with the following:
1. Visual Studio 2017 15.4.1
2. OS: Windows 8.1 64 bit
3. OpenCV 3.3.1
4. CMake 3.9.4 win64 x64
5. CUDA 9.0.176
Compute Capability 2.1
I generate the visual studio solution using CMake.
When it comes to building openCV, all the projects in the build order are built successfully. When open_cv core
is built, the compiler emits the following:
Build started: Project: opencv_core, Configuration: Debug x64 ------

Is there a step I am missing or is the CUDA toolkit version incompatible with the openCV version?
Tried googling and stack overflow cant find someone with the exact same problem.

Detecting video playback error
Hello all,
I am attempting to detect playback error, notably during transitions of videos being displayed. The types of error include:
- Video flickering (videos goes black, or goes white)
- Distortions, artifacts
- Unexpectedly blurry video (ie, 1920x1080 looks like 640x480)
- Huge FPS drops (lack of smooth transitions during playback)
Currently, I have applied edge detection and Hough transform to detect sharp changes from frame to frame with moderate success for the first two issues, but am not sure whether these solutions are optimal.
If there are better solutions out there, I'd love to try them! Thanks.

OpenCV calibration vs. Matlab calibration accuracy
Hello,
So I've programmed a simulation to project a plane onto a flat screen.
 
The red circle is my "camera", the blue is the object being projected, and the green are the 2D image point projections.
So, I know exactly where my camera is in my simulation.
I used OpenCV calibrateCamera() and used the returned camera matrix to find the camera location coordinates, and then compared that with the actual one, and my normalized distance error is .000301162. I tried increasing the amount of iterations for my term criteria, but it just converges at this number.
Then I also used MATLAB estimateCameraParameters(), and my normalized distance error was 1.76E-12.
To summarize:
Source error for OpenCV = .000301162.
Source error for MATLAB = 1.76E-12.
This is a significant difference, and I was wondering if there were any settings or additional functions in OpenCV that will make my values turn out the same as MATLAB's, and if there is any reason to why this is like this.

Every time I create a new project in Code::Blocks and try to compile the example, it gives me the error /home/billy/Pictures/Stuff/main.cpp:8: undefined reference to `cv::imread(cv::String const&, int)' and /home/benjymon/Pictures/Stuff/main.cpp:11: undefined reference to `cv::namedWindow(cv::String const&, int)' and 7 other errors like these.

OpenCV 3.4.1 & GCC5.1.0 with codeblocks in windows
Does this combination works ? OpenCV 3.4.1 + Contrib & GCC5.1.0 with codeblocks in windows. I am getting several errors while compiling.
In cmake I have disabled matlab, examples, java, python, proto, vtk, ipp, precompiled headers.
This is because I was getting different errors, and disabled these to clear one by one errors. Now at the stage of 43% of compilation I get error, which I have copied below. Request for inputs to sort out the error. Any suggestion on the tools combination?

openCV3 - Python Docs
Hello:
I'm a bit lost. Recently switched to openCV 3.4.1 for Python 3.6.5. I previously used 2.4 with python 2.7. So I am finding a number of syntax changes when calling cv funtions in my python scripts. I try to make the needed corrections by using the tutorial and doc examples but it seems most of these only show examples for C++ where in 2.4 would show both C++ and Python programming examples.
Maybe I'm missing something/understanding how mitigate resolving these syntax errors. Any help and insights are much apreciated.

error 2 compiling OpenCV3.4 with Cmake
Hi, i´m trying to compile OpenCV 3.4 with CMake 3.11.3 and when it reach 41% ( when is trying to compile window_w32.cpp which is inside highgui source code) i am getting several errors, for example:
error: MONITOR_DEFAULTTONEAREST was not decleared in this scope.
....
...
make [1] [modules/highgui/CMakeFiles/opencv_highgui.dir/all] error 2
The generator for the cmake project is MSYS MAKEFILES, using default native compilers.
The compiler is MINGW.
I would really appreciate your help.
Thanks.

CMake Error at cmake/OpenCVDetectCXXCompiler.cmake
Hello everyone! This is my first post. I'm having trouble with compiling OpenCV in openSUSE Tumbleweed. I get an error when I try to configure with both cmake-gui and cmake. Error is:
CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:85 (list):
list GET given empty list
Call Stack (most recent call first):
CMakeLists.txt:109 (include)
CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:86 (list):
list GET given empty list
Call Stack (most recent call first):
CMakeLists.txt:109 (include)
CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:89 (math):
math cannot parse the expression: "*100 + ": syntax error, unexpected
exp_TIMES, expecting exp_OPENPARENT or exp_NUMBER (1)
Call Stack (most recent call first):
CMakeLists.txt:109 (include)
Following line after the error is that:
Detected version of GNU GCC: ()
Is it meaning that something is wrong with the GCC, because there should be version written inside the brackets?
I don't know much about cmake to solve this problem, so unfortunately I'm stuck.
cmake version 3.2.3
gcc version 5.1.1 20150622 [gcc-5-branch revision 224722] (SUSE Linux)
Itried both opencv-3.0.0 and opencv-master but got same error.

compiling error on TK1 board
Hello,
I have build Opencv 3.3 on TK1 on single core. Then i started implementing the algorithm. Which were working fine. But then because of need i needed all the cores to work. then i made all cores to online. Now my all cores are online but code is giving compilation error. i am not getting the reason why this happened. But is this right that opencv build on single core might not work on multicore? or any other reason behind this?
Thanks in advance.
