int main()

{

Mat img = imread("Lennared.jpg");

Mat mask, inpainted;

 //inRange(img, Scalar(0, 0, 250), Scalar(0, 0, 255),mask);

//mask = Mat::zeros(img.size(), img.type()); // creating a mask image 

mask = img.clone(); // cloning the same image and putting it into mask

 cvtColor(mask, mask, CV_RGB2GRAY);

threshold(mask, mask, 100 ,255, CV_THRESH_BINARY);

inpaint(img, mask, inpainted,3,CV_INPAINT_TELEA);

for (int key = 0; 27 != key; key = waitKey())

{
    switch (key)

    {

    case 'm': imshow("image mask", mask);

        break;

    case 'i': imshow("inpainted image", inpainted);

there is an example here and without your code we cannot help you

can you take another look at the example code ? you cannot use your image as a mask, but have to manually specify (eg, by drawing with the mouse) regions in a black uchar image, where inpainting on the original should be applied.

Mat img = imread("Lennared.jpg");

Mat mask, inpainted;

cvtcolor(img,mask,CV_BRG2GRAY);

inrange(img, Scalar(10,10,200), Scalar(40,40,255),mask); // make sure your targeted color is between the range you stated

inpaint(img,mask, inpainted,3,CV_INPAINT_TELEA);

for( int key =0 ; 23 !-key; key=waitKey())
{
    switch (key)
{
   case 'm' : imshow("maskimage", mask)
break;
case 'i ': imshow("inpainted image", inpainted)
break;
default : imshow("original" img);


}


}
return 0;

since am i trying to detect the red color in the image, i have to pass the scalar value of the red color, that from a lower range to a higher range all inclusive... That should give you the perfect mask image for use in the inpaint function, hope this help everyone else ..
