public static void inpaint​(Mat src,
Mat dst,
int algorithmType)
The function implements different single-image inpainting algorithms. See the original papers CITE: He2012 (Shiftmap) or CITE: GenserPCS2018 and CITE: SeilerTIP2015 (FSR) for details.
Parameters:
src - source image
• #INPAINT_SHIFTMAP: it could be of any type and any number of channels from 1 to 4. In case of 3- and 4-channels images the function expect them in CIELab colorspace or similar one, where first color component shows intensity, while second and third shows colors. Nonetheless you can try any colorspaces.
• #INPAINT_FSR_BEST or #INPAINT_FSR_FAST: 1-channel grayscale or 3-channel BGR image.
mask - mask (#CV_8UC1), where non-zero pixels indicate valid image area, while zero pixels indicate area to be inpainted
dst - destination image
algorithmType - see xphoto::InpaintTypes
• #### oilPainting

Parameters:
src - Input three-channel or one channel image (either CV_8UC3 or CV_8UC1)
dst - Output image of the same size and type as src.
size - neighbouring size is 2-size+1
dynRatio - image is divided by dynRatio before histogram processing
code - automatically generated

Performs image denoising using the Block-Matching and 3D-filtering algorithm <http://www.cs.tut.fi/~foi/GCF-BM3D/BM3D_TIP_2007.pdf> with several computational optimizations. Noise expected to be a gaussian white noise.
Parameters:
src - Input 8-bit or 16-bit 1-channel image.
dstStep1 - Output image of the first step of BM3D with the same size and type as src.
dstStep2 - Output image of the second step of BM3D with the same size and type as src.
h - Parameter regulating filter strength. Big h value perfectly removes noise but also removes image details, smaller h value preserves details but also preserves some noise.
templateWindowSize - Size in pixels of the template patch that is used for block-matching. Should be power of 2.
searchWindowSize - Size in pixels of the window that is used to perform block-matching. Affect performance linearly: greater searchWindowsSize - greater denoising time. Must be larger than templateWindowSize.
blockMatchingStep1 - Block matching threshold for the first step of BM3D (hard thresholding), i.e. maximum distance for which two blocks are considered similar. Value expressed in euclidean distance.
blockMatchingStep2 - Block matching threshold for the second step of BM3D (Wiener filtering), i.e. maximum distance for which two blocks are considered similar. Value expressed in euclidean distance.
groupSize - Maximum size of the 3D group for collaborative filtering.
slidingStep - Sliding step to process every next reference block.
beta - Kaiser window parameter that affects the sidelobe attenuation of the transform of the window. Kaiser window is used in order to reduce border effects. To prevent usage of the window, set beta to zero.
normType - Norm used to calculate distance between blocks. L2 is slower than L1 but yields more accurate results.
step - Step of BM3D to be executed. Possible variants are: step 1, step 2, both steps.
transformType - Type of the orthogonal transform used in collaborative filtering step. Currently only Haar transform is supported. This function expected to be applied to grayscale images. Advanced usage of this function can be manual denoising of colored image in different colorspaces. SEE: fastNlMeansDenoising

dst - Output image of the same size and type as src.
gainB - gain for the B channel
gainG - gain for the G channel
gainR - gain for the R channel

• #### createTonemapDurand

public static TonemapDurand createTonemapDurand​(float gamma,
float contrast,
float saturation,
float sigma_color,
float sigma_space)
Creates TonemapDurand object You need to set the OPENCV_ENABLE_NONFREE option in cmake to use those. Use them at your own risk.
Parameters:
gamma - gamma value for gamma correction. See createTonemap
contrast - resulting contrast on logarithmic scale, i. e. log(max / min), where max and min are maximum and minimum luminance values of the resulting image.
saturation - saturation enhancement value. See createTonemapDrago
sigma_color - bilateral filter sigma in color space
sigma_space - bilateral filter sigma in coordinate space
Returns:
automatically generated
