Classes

class  cv::AlignExposures
 The base class for algorithms that align images of the same scene with different exposures. More...
 
class  cv::AlignMTB

 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. More...
