Detailed Description

Performs exemplar-based image inpainting.

Completes a masked part of an image with patches copied from other regions in the image. Motivated by the image completion algorithm of Criminisi et al., IEEE TIP, 2004 using the PatchMatch algorithm of Barnes et al. for finding patch candidates. An example code snippet is provided below:

cv::Mat img = cv::imread(imageFilename, CV_LOAD_IMAGE_COLOR);
DRWN_ASSERT_MSG(img.data, "could not read image from " << imageFilename);
 
cv::Mat mask = cv::Mat::zeros(img.rows, img.cols, CV_8UC1);
cv::rectangle(mask, cv::Point(img.cols / 4, img.rows / 4),
    cv::Point(3 * img.cols / 4, 3 * img.rows / 4), cv::Scalar(0xff), -1);

drwnImageInPainter inpainter(3);
inpainter.bVisualize = true;
cv::Mat output = inpainter.fill(img, mask);

cv::imwrite(outputFilename, output);
