def L0Smooth(clip, lamda=2e-2, kappa=2, color=True, **depth_args):
"""L0 Smooth in VapourSynth
It is also known as "L0 Gradient Minimization".
L0 smooth is a new image editing method, particularly effective for sharpening major edges
by increasing the steepness of transitions while eliminating a manageable degree of low-amplitude structures.
It is achieved in an unconventional optimization framework making use of L0 gradient minimization,
which can globally control how many non-zero gradients are resulted to approximate prominent structures in a structure-sparsity-management manner.
Unlike other edge-preserving smoothing approaches, this method does not depend on local features and globally locates important edges.
It, as a fundamental tool, finds many applications and is particularly beneficial to edge extraction, clip-art JPEG artifact removal, and non-photorealistic image generation.
All the internal calculations are done at 32-bit float.
Args:
clip: Input clip with no chroma subsampling.
lamda: (float) Smoothing parameter controlling the degree of smooth.
A large "lamda" makes the result have very few edges.
Typically it is within the range [0.001, 0.1].
This parameter is renamed from "lambda" for better compatibility with Python.
Default is 0.02.
kappa: (float) Parameter that controls the convergence rate of alternating minimization algorithm.
Small "kappa" results in more iteratioins and with sharper edges.
kappa = 2 is suggested for natural images, which is a good balance between efficiency and performance.
Default is 2.
color: (bool) Whether to process data collaboratively.
If true, the gradient magnitude in the model is defined as the sum of gradient magnitudes in the original color space.
If false, channels in "clip" will be processed separately.
Default is True.
depth_args: (dict) Additional arguments passed to mvf.Depth() in the form of keyword arguments.
Default is {}.

"""L0 Gradient Projection in VapourSynth
L0 gradient projection is a new edge-preserving filtering method based on the L0 gradient.
In contrast to the L0 gradient minimization, L0 gradient projection framework is intuitive
because one can directly impose a desired L0 gradient value on the output image.
The constrained optimization problem is minimizing the quadratic data-fidelity subject to the hard constraint that
the L0 gradient is less than a user-given parameter "alpha".
The solution is based on alternating direction method of multipliers (ADMM), while the hard constraint is handled by
projection onto the mixed L1,0 pseudo-norm ball with variable splitting, and the computational complexity is O(NlogN).
However, current implementation here is extremely slow. In my experiment, the number of iteration of this algorithm is far more than L0Smooth.
All the internal calculations are done at 32-bit float.
Args:
clip: Input clip with no chroma subsampling.
alpha: (float) L0 gradient of output in percentage form, i.e. the range is [0, 1].
It can be seen as the degree of flatness in the output.
Default is 0.08.
precision: (float) Precision of the calculation of L0 gradient. The larger the value, the more accurate the calculation.
Default is 255.
epsilon: (float) Stopping criterion in percentage form, i.e. the range is [0, 1].
It determines the allowable error from alpha.
Default is 0.0002.
maxiter: (int) Maximum number of iterations.
Default is 5000.
gamma: (int) Step size of ADMM.
Default is 3.
eta: (int) Controling gamma for nonconvex optimization.
It stabilizes ADMM for nonconvex optimization.
According to recent convergence analyses of ADMM for nonconvex cases, under appropriate conditions,
the sequence generated by ADMM converges to a stationary point with sufficiently small gamma.
Default is 0.95.
depth_args: (dict) Additional arguments passed to mvf.Depth() in the form of keyword arguments.
Default is {}.
