Hello guys,

I have a big problem. I am initiant in the kinect and i don't know install the Kinect with OpenCV C++ on the Visual Studio.

My initial aim is open a frame of the Kinect and show this frame.

Thanks.

I need apply the zoom in and zoom out in the imagem of the my form with OpenCV. But, my great problem is that I don't know whats the function I use in the Visual Studio C++. In the examples of the internet the zoom in and zoom out are applied with Visual C# or Visual Basic.

I'm having a problem with image rotation.

Risks are distorting when I apply distortion. How to rotate the image without distortion ?

Hello guys, I need to use the BRISK method for detecting the key points in an image.

Can someone help me ?

Someone has some algorithm ready for me to test and verify the detection of the key points with BRISK?

How to install dlib library in the visual studio 2012, to work together with Opencv library?

thanks!

There is another method besides Haar to detect eye, nose and mouth in the image? Because I was using the Haar and when the face is up, it detects more than one eye, nose and mouth.

Can someone help me.

My Code

Correct the topic and put the image of my program and error that occurs when I want to save my image with the .jpg format.

Hello guys, good night. I installed the opencv 3.0, but when I use the command to save the image, when this error occurs.

This error only occurs when saving the image to jpg format.

If I save to .bmp format, you save the image as normal.

Someone can explain me how to solve this problem?

Below, this is my error that occur in my program.

Thank you.

Hello friend, good night. I could fix the problem. For this, I again all the steps to install and work properly. Thanks,

Hello Brandon , good morning.

I followed all the tutorial and after installation, the VS2012 recognizes all the libraries, functions and opecv structures, but this error occurs at compile time.

Below is the link to my set design. You can find what the problem and give me an answer?

If wrong, can you send me your tutorial for me to use and configure again?

Thank you.

Hello guys, good night.

I installed the 3.0 opencv, but every time I run my code, this error occurs.

Can anyone help me, because I've tried several ways, but I can not solve this problem.

Thanks,

You can use the minimum and maximum values of the rectangle to know. If the contour has passed, then the initial coordinate (x0, y0) and the end coordinate (x0 + x.width, y0 + y.height) rectangle, will be to the left side of the line you marked in the image.

How do I soften this region that is marked in my image? I need to let these two uniform regions.

I have already applied several low pass filters, but I can not make them uniform.

Thanks,

Hello guy,

Thanks by the help.

Your code helped me a lot.

I need close the contour, but i don't understand how to use the approxpolydp function.

This image below is my open contour.

StevenPuttemans I need to mount the panoramic face image.

thdrksdfthmn I already tried to use stitching, but don't work very well.

Yes I want. But I do not know how to rotate the first image according to the yellow dots and yellow dots of the second image.

Hello guy!

I want to do this: link text

Can you help me ? My big question is how to accomplish a transformation with the left image to list the yellow dots on the left of the image with the yellow dots on the right of the image. Thanks!

Hello guys, good night. I am studying to assemble the mosaic of a face. Does anyone know tell me what function can I use to join the yellow dots on the left of the image with the yellow dots on the right image and assemble the mosaic?I need to modify the image left joins the right. I appreciate the help.

Hello everyone, How can I extract the attributes of an image for me to recognize any object in the image?I need to extract these data with the SIFT, SURF and Brief. Thank you.

Hello guy, You want to cut the two images by size.I have this function.

 Mat crop( Mat ent)

{ int maior_x, maior_y, menor_x, menor_y;

menor_x = maior_x = menor_y = maior_y = 900;

for(int rows = 900; rows < ent.rows; rows++) { for(int cols = 900; cols < ent.cols; cols++) { if(ent.at<vec3b>(rows, cols)[0] != 0 && ent.at<vec3b>(rows, cols)[1] != 0 && ent.at<vec3b>(rows, cols)[2] != 0 ) { if(rows < menor_y) { menor_y = rows; }

        if(rows > maior_y)
        {
            maior_y = rows;
        }

        if(cols < menor_x)
        {
            menor_x = rows;
        }

        if(cols > maior_x)
        {
            maior_x = cols;
        }
    }
}

}

Anyone know how to filter the key points in the sift and surf methods, for evite to generate errors in the homography matrix.

Can someone help me ? How do you solve this problem? In some images this error occurs in mosaic construction phase.

But the people here don't help me! Sorry! Can you help me ?

Is there a function to compute the statistical moment in opencv ? I want to compute these moments, but i don't know what is the function or method used.

Thanks
