inline auto splinart::build_img(const std::array<std::size_t, 2> &img_size, std::vector<Circle> &circles, std::size_t rep = 300, bool periodic = true, double scale_color = 0.005, double scale_value = 0.00001)#

Update the image using a cubic spline on a shape.

Parameters:

  • img_size – The size of the squared output image.

  • circles – The list of circles to plot on th image.

  • rep – Number of iterations (default is 300).

  • periodic – Define if the first and last points of the path must be equal (default is True).

  • scale_color – Scale the given color (default is 0.005).

  • scale_value – Rescale the random radius (default value is 0.00001).

inline void splinart::update_path(xt::xtensor<double, 2> &path, double scale_value = 0.00001, bool periodic = false)#

Update the path of the spline.

We move each point of the path by a random vector defined inside a circle where

  • the center is the point of the path

  • the radius is a random number between [-1, 1]

Parameters:

  • path – The coordinates of the cubic spline.

  • periodic – If True, the first and the last points of the path are the same (the default value is False).

  • scale_value – Rescale the random radius (default value is 0.00001).

inline void splinart::draw_pixel(xt::xtensor<double, 3> &img, const xt::xtensor<double, 2> &spline, xt::xtensor_fixed<double, xt::xshape<4>> color)#

Add pixels on the image.

Parameters:

  • img – The image where we add pixels.

  • spline – The coordinates of the pixels to add.

  • color – Define the RGBA color of the pixels.

inline void splinart::imshow(xt::xtensor<double, 3> &img)#

Show the result image using the imshow function of OpenCV.

Parameters:

img – The image to draw
