I got this error while try to connect with matlab 2015a

how can I connect opencv with matlab?

opencv2.1 to opencv3.1

I just need something that can help me convert the old version to the new one.

BTW any guide to recompile this code? Any tutorial, or something to read so I can rebuild it?

ya.. it seems like I have to rebuild the code. Because there is another error occur. can you take a look here http://answers.opencv.org/question/92594/error-c2665-regarding-imshow/ @berak

Here I provide the output of build:

error C2665: 'cv::imshow' : none of the 2 overloads could convert all the argument types
1>          c:\opencv30\opencv310\opencv\build\include\opencv2\highgui.hpp(552): could be 'void cv::imshow(const cv::String &,const cv::ogl::Texture2D &)'
1>          c:\opencv30\opencv310\opencv\build\include\opencv2\highgui.hpp(372): or       'void cv::imshow(const cv::String &,cv::InputArray)'
1>          while trying to match the argument list '(const char *, IplImage *)'

It looks like the problem come from this code:

IplImage* frameShow = new IplImage(frameShowWin);
//others code
imshow(name, frameShow);

And I'm not sure what the first row code do. From my knowledge, IplImage is c language of older version (2.1 etc.). Since I'm compiling this code on MVS 2013 & using OpenCV 3.1.0, probably some code is not converted.

I download a source code from internet. There is no instruction on developing this code except that it said it uses Microsoft visual studio and opencv 2.1. Then I found in the additional include file consist of file from Eigen 2.0.17. So I install it and include it in the project. However there are errors as stated above. How should I use this Eigen thing in this project?

I just found the solution since I found the error is develop at imshow();. So, to avoid this error I include the code as follow:

if (!frame.empty())
{
cv::imshow("image", frame);
}

I'm not sure why, btw. If someone can explain this.

I test my code with .png format it run as I wish. But when I run with .jpg, the program break. My jpg images have 24-bit depth, while my png images are 16-bit depth. I guess this is related to the problem. Any solution?

the test is actually for what purpose? (sorry for being curious)

Maybe you can try to watch this video

thanks @Tetragramm. @berak what is the reason of applying Gaussian blur in this case?

@Tetragramm thank you for noticing the ring anyway. Can't I get smooth foreground btw? Where there is no black pixel on the foreground?

@Tetragramm suppose the original is RGB. only the background is in black, but the foreground should be in color as original as captured by camera.

Maybe you can watch this video first: opencv-python. Then you can try to understand this tutorial

@nena can you share me the code for background subtraction which produce the output for the first image?

thanks @LBerger for your effort. I'd tried the suggested solution but it leads me to more question. Anyway, I 'solve' it by using the tutorial provided inside the samples folder in opencv. To conclude it, I think there is some setting mistakes I'd made previously, like the additional directory so on.

I work with background subtraction using MOG2 method & obtained as the foreground image below:

As shows above, I fail to get exact pixel as the original frame. What should I do?

@VladislavVinogradov Is it true some version of OpenCV doesn't have MOG? I'm using version 3.0.0 rc1. When I check background_segm.hpp, there is only for MOG2 & KNN method.

@LBerger I've updated with the picture. & This is the Debug output: The thread 0x25fc has exited with code -1073741701 (0xc000007b). The thread 0xd38 has exited with code -1073741701 (0xc000007b). The thread 0x1274 has exited with code -1073741701 (0xc000007b). The program '[3300] backgroundsubtraction.exe' has exited with code -1073741701 (0xc000007b).

I try to run tutorial for Background subtraction. But the output said "The application can't start correctly ...." I try many solution proposed in here and others website. How can I solve this problem. Output ERROR as follow:

@deltamaster what is static library folder? where is it?

which mean CMake doesn't generate opencv_core? @berak @ran294

Is there any different between the methods for color image?

@StevenPuttemans do you have any idea, what face detection method for video-based application is suitable for real-time purpose? By reducing image size will not help in many applications which require details.

@jayrambhia is it real-time? how fast it is?

the method can perform real-time @lightalchemist ?

In order to speed up face detection process, some will reduce the video or image dimension. Will it makes the resolution become worst and effect the face recognition process?

Some conversion is require from raw data in the buffer into opencv Mat type. It is crucial to know the data type in buffer (CV_datatype). refer here (http://answers.opencv.org/question/71401/mat-from-buffer/)

@pklab , I'd solved the problem. There is a header file that I should include in the coding. Thank you very much. But can I ask about the <atomic> ? Actually in my pc I'm running with Visual Studio version 2008 because I'm using some library that only work with old version of Visual Studio. So this old version does not provide this new class. So is there any others solution for that?

@pklab. Ya I'd tried. And there is no error.

But there are some outputs like this:

'ConsoleApplication2.exe' (Win32): Loaded 'C:\Windows\SysWOW64\ntdll.dll'. Cannot find or open the PDB file.

And end up with this output when I click 'Grab':

The thread 0x1f24 has exited with code 0 (0x0).
The thread 0x20c0 has exited with code 0 (0x0).
The thread 0xf7c has exited with code 0 (0x0).
The program '[10004] ConsoleApplication2.exe' has exited with code 0 (0x0).

Thanks @pklab . But when I click 'Grab' button, the program exited. I wonder if this thing just happen to my machine or what.
