◆ denoise_TVL1() [1/3]

static void OpenCVForUnity.PhotoModule.Photo.denoise_TVL1 ( List< Mat > observations,
Mat result )
static

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 [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 [ChambolleEtAl], it might make sense to skim over it here, following [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
observationsThis array should contain one or more noised versions of the image that is to be restored.
resultHere 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.
lambdaCorresponds 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.
nitersNumber 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.

templateWindowSizeSize in pixels of the template patch that is used to compute weights. Should be odd. Recommended value 7 pixels
searchWindowSizeSize in pixels of the window that is used to compute weighted average for given pixel. Should be odd. Affect performance linearly: greater searchWindowsSize - greater denoising time. Recommended value 21 pixels

◆ seamlessClone() [1/3]

in Vec2d p,
Mat blend,
int flags )
static

Image editing tasks concern either global changes (color/intensity corrections, filters, deformations) or local changes concerned to a selection. Here we are interested in achieving local changes, ones that are restricted to a region manually selected (ROI), in a seamless and effortless manner. The extent of the changes ranges from slight distortions to complete replacement by novel content [PM03] .

Parameters
srcInput 8-bit 3-channel image.
dstInput 8-bit 3-channel image.
maskInput 8-bit 1 or 3-channel image.
pPoint in dst image where object is placed.
blendOutput image with the same size and type as dst.
flagsCloning method that could be cv::NORMAL_CLONE, cv::MIXED_CLONE or cv::MONOCHROME_TRANSFER

◆ stylization() [1/3]

static void OpenCVForUnity.PhotoModule.Photo.stylization ( Mat src,
Mat dst )
static

Stylization aims to produce digital imagery with a wide variety of effects not focused on photorealism. Edge-aware filters are ideal for stylization, as they can abstract regions of low contrast while preserving, or enhancing, high-contrast features.

Parameters
srcInput 8-bit 3-channel image.
dstOutput image with the same size and type as src.
sigma_sRange between 0 to 200.
sigma_rRange between 0 to 1.

◆ stylization() [2/3]

static void OpenCVForUnity.PhotoModule.Photo.stylization ( Mat src,

float sigma_s )
static

Stylization aims to produce digital imagery with a wide variety of effects not focused on photorealism. Edge-aware filters are ideal for stylization, as they can abstract regions of low contrast while preserving, or enhancing, high-contrast features.

Parameters
srcInput 8-bit 3-channel image.
dstOutput image with the same size and type as src.
sigma_sRange between 0 to 200.
sigma_rRange between 0 to 1.

◆ textureFlattening() [1/4]

static void OpenCVForUnity.PhotoModule.Photo.textureFlattening ( Mat src,
Mat mask,
Mat dst )
static

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.

Parameters
srcInput 8-bit 3-channel image.
maskInput 8-bit 1 or 3-channel image.
dstOutput image with the same size and type as src.
low_thresholdRange from 0 to 100.
high_thresholdValue > 100.
kernel_sizeThe size of the Sobel kernel to be used.
Note
The algorithm assumes that the color of the source image is close to that of the destination. This assumption means that when the colors don't match, the source image color gets tinted toward the color of the destination image.
