Classes#
class cv::AlignExposures
The base class for algorithms that align images of the same scene with different exposures. More…
class cv::AlignMTB
This algorithm converts images to median threshold bitmaps (1 for pixels brighter than median luminance and 0 otherwise) and than aligns the resulting bitmaps using bit operations. More…

Functions#
void cv::decolor (InputArray src, OutputArray grayscale, OutputArray color_boost)
Transforms a color image to a grayscale image. It is a basic tool in digital printing, stylized black-and-white photograph rendering, and in many single channel image processing applications [196] .
void cv::colorChange (InputArray src, InputArray mask, OutputArray dst, float red_mul=1.0f, float green_mul=1.0f, float blue_mul=1.0f)
Given an original color image, two differently colored versions of this image can be mixed seamlessly.
void cv::illuminationChange (InputArray src, InputArray mask, OutputArray dst, float alpha=0.2f, float beta=0.4f)
Applying an appropriate non-linear transformation to the gradient field inside the selection and then integrating back with a Poisson solver, modifies locally the apparent illumination of an image.
void cv::seamlessClone (InputArray src, InputArray dst, InputArray mask, Point p, OutputArray blend, int flags)
Performs seamless cloning to blend a region from a source image into a destination image. This function is designed for local image editing, allowing changes restricted to a region (manually selected as the ROI) to be applied effortlessly and seamlessly. These changes can range from slight distortions to complete replacement by novel content [244].
void cv::textureFlattening (InputArray src, InputArray mask, OutputArray dst, float low_threshold=30, float high_threshold=45, int kernel_size=3)
By retaining only the gradients at edge locations, before integrating with the Poisson solver, one washes out the texture of the selected region, giving its contents a flat aspect. Here Canny Edge Detector is used.
void cv::correctChromaticAberration (InputArray input_image, InputArray coefficients, OutputArray output_image, const Size &image_size, int calib_degree, int bayer_pattern=-1)
Corrects lateral chromatic aberration in an image using polynomial distortion model.
void cv::loadChromaticAberrationParams (const FileNode &node, OutputArray coeffMat, Size &calib_size, int °ree)
Load chromatic-aberration calibration parameters from opened FileStorage.
void cv::denoise_TVL1 (const std::vector< Mat > &observations, Mat &result, double lambda=1.0, int niters=30)
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.
void cv::fastNlMeansDenoising (InputArray src, OutputArray dst, const std::vector< float > &h, int templateWindowSize=7, int searchWindowSize=21, int normType=NORM_L2)
