  public static void inpaint(Mat src, Mat inpaintMask, Mat dst, double inpaintRadius, int flags)
  
  Restores the selected region in an image using the region neighborhood.
  Parameters:
  
  src - Input 8-bit, 16-bit unsigned or 32-bit float 1-channel or 8-bit 3-channel image.
  
  inpaintMask - Inpainting mask, 8-bit 1-channel image. Non-zero pixels indicate the area that needs to be inpainted.
  
  dst - Output image with the same size and type as src .
  
  inpaintRadius - Radius of a circular neighborhood of each point inpainted that is considered by the algorithm.
  
  flags - Inpainting method that could be cv::INPAINT_NS or cv::INPAINT_TELEA The function reconstructs the selected image area from the pixel near the area boundary. The function may be used to remove dust and scratches from a scanned photo, or to remove undesirable objects from still images or video. See <http://en.wikipedia.org/wiki/Inpainting> for more details. Note:

  public static void denoise_TVL1(List<Mat> observations, Mat result, double lambda, int niters)
  
  Primal-dual algorithm is an algorithm for solving special types of variational problems (that is, finding a function to minimize some functional). As the image denoising, in particular, may be seen as the variational problem, primal-dual algorithm then can be used to perform denoising and this is exactly what is implemented. It should be noted, that this implementation was taken from the July 2013 blog entry CITE: MA13 , which also contained (slightly more general) ready-to-use source code on Python. Subsequently, that code was rewritten on C++ with the usage of openCV by Vadim Pisarevsky at the end of July 2013 and finally it was slightly adapted by later authors. Although the thorough discussion and justification of the algorithm involved may be found in CITE: ChambolleEtAl, it might make sense to skim over it here, following CITE: MA13 . To begin with, we consider the 1-byte gray-level images as the functions from the rectangular domain of pixels (it may be seen as set \(\left\{(x,y)\in\mathbb{N}\times\mathbb{N}\mid 1\leq x\leq n,\;1\leq y\leq m\right\}\) for some \(m,\;n\in\mathbb{N}\)) into \(\{0,1,\dots,255\}\). We shall denote the noised images as \(f_i\) and with this view, given some image \(x\) of the same size, we may measure how bad it is by the formula \(\left\|\left\|\nabla x\right\|\right\| + \lambda\sum_i\left\|\left\|x-f_i\right\|\right\|\) \(\|\|\cdot\|\|\) here denotes \(L_2\)-norm and as you see, the first addend states that we want our image to be smooth (ideally, having zero gradient, thus being constant) and the second states that we want our result to be close to the observations we've got. If we treat \(x\) as a function, this is exactly the functional what we seek to minimize and here the Primal-Dual algorithm comes into play.
  
  Parameters:
  
  observations - This array should contain one or more noised versions of the image that is to be restored.
  
  result - Here the denoised image will be stored. There is no need to do pre-allocation of storage space, as it will be automatically allocated, if necessary.
  
  lambda - Corresponds to \(\lambda\) in the formulas above. As it is enlarged, the smooth (blurred) images are treated more favorably than detailed (but maybe more noised) ones. Roughly speaking, as it becomes smaller, the result will be more blur but more sever outliers will be removed.
  
  niters - Number of iterations that the algorithm will run. Of course, as more iterations as better, but it is hard to quantitatively refine this statement, so just use the default and increase it if the results are poor.

If we treat \(x\) as a function, this is exactly the functional what we seek to minimize and here the Primal-Dual algorithm comes into play.
  
  Parameters:
  
  observations - This array should contain one or more noised versions of the image that is to be restored.
  
  result - Here the denoised image will be stored. There is no need to do pre-allocation of storage space, as it will be automatically allocated, if necessary. (blurred) images are treated more favorably than detailed (but maybe more noised) ones. Roughly speaking, as it becomes smaller, the result will be more blur but more sever outliers will be removed. better, but it is hard to quantitatively refine this statement, so just use the default and increase it if the results are poor.
