Hello, I am trying to filter my depth data captured from kinect. Look at the image below. unknown values are colored with black: image description

Now I want to use the cv::inpaint function but still I have no luck. I followed this article: but I am using different kinect drivers. I am using Kinect SDK.

here are my code:

int drawDepth(HANDLE h, IplImage* depth)
{
const NUI_IMAGE_FRAME * pImageFrame = NULL;
HRESULT hr = NuiImageStreamGetNextFrame( h, 0, &pImageFrame );

Mat depthMat(Size(640,480), CV_16UC1);
Mat depthf(Size(640,480), CV_8UC1);


if( FAILED(hr))
{
cout<<"Get Image Frame Failed"<<endl;
return -1;
}

INuiFrameTexture * pTexture = pImageFrame->pFrameTexture;
NUI_LOCKED_RECT LockedRect;
pTexture->LockRect( 0, &LockedRect, NULL, 0 );

if( LockedRect.Pitch != 0 )
{
BYTE *pBuffer = (BYTE*)LockedRect.pBits;
cvSetData(depth, pBuffer, LockedRect.Pitch);
//cvShowImage("Depth Image", depth); // show normal depth maps

depthMat = depth;
depthMat.convertTo(depthf, CV_8UC1, 255.0/2048.0);

Mat _tmp, _tmp1;
Mat (depthMat-400.0).convertTo(_tmp1, CV_64FC1);

Point minLoc; double minval,maxval;
minMaxLoc(_tmp1, &minval, &maxval, NULL,NULL);
_tmp1.convertTo(depthf, CV_8UC1, 255.0/maxval);

//use a smaller version of the image
Mat small_depthf; 
resize(depthf, small_depthf, Size(), 0.2, 0.2);

//inpaint only the "unknown" pixels
cv::inpaint(small_depthf,( small_depthf == 255), _tmp1, 5.0, INPAINT_TELEA);

resize(_tmp1, _tmp, depthf.size());
_tmp.copyTo(depthf, (depthf==255));

cv::imshow("test", depthf); // show inpainted depth maps
}
NuiImageStreamReleaseFrame(h, pImageFrame);
return 0;
}

This simply means that your code is unable to find the opencv library that contains the function inpaint. You will need to provide the location of library to visual studio. Check the linker settings in project properties.

I think linker settings was correct since I already used opencv functions like resize etc... so which file does the inpaint method belongs?

it works. I added the opencv_photo245d.lib :D
