  2. Line integral convolution - Wikipedia

    en.wikipedia.org/wiki/Line_integral_convolution

    If carried out naively, this is quite expensive. First, the field lines have to be computed using a numerical method for solving ordinary differential equations, like a Runge–Kutta method, and then for each pixel the convolution along a field line segment has to be calculated. The final image will normally be colored in some way.

  3. Planar straight-line graph - Wikipedia

    en.wikipedia.org/wiki/Planar_straight-line_graph

    An example of planar straight-line graph In computational geometry and geometric graph theory , a planar straight-line graph (or straight-line plane graph , or plane straight-line graph ), in short PSLG , is an embedding of a planar graph in the plane such that its edges are mapped into straight-line segments. [ 1 ]

  4. Weighted Voronoi diagram - Wikipedia

    en.wikipedia.org/wiki/Weighted_Voronoi_diagram

    In a multiplicatively weighted Voronoi diagram, the distance between a point and a site is divided by the (positive) weight of the site. [1] In the plane under the ordinary Euclidean distance , the multiplicatively weighted Voronoi diagram is also called circular Dirichlet tessellation [ 2 ] [ 3 ] and its edges are circular arcs and straight ...

  6. Curve fitting - Wikipedia

    en.wikipedia.org/wiki/Curve_fitting

    Fitting of a noisy curve by an asymmetrical peak model, with an iterative process (Gauss–Newton algorithm with variable damping factor α).Curve fitting [1] [2] is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, [3] possibly subject to constraints.

  7. Simulink - Wikipedia

    en.wikipedia.org/wiki/Simulink

    Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems.Its primary interface is a graphical block diagramming tool and a customizable set of block libraries.

  8. Overlap–add method - Wikipedia

    en.wikipedia.org/wiki/Overlap–add_method

    The two methods are also compared in Figure 3, created by Matlab simulation. The contours are lines of constant ratio of the times it takes to perform both methods. When the overlap-add method is faster, the ratio exceeds 1, and ratios as high as 3 are seen. Fig 3: Gain of the overlap-add method compared to a single, large circular convolution.

  9. Line fitting - Wikipedia

    en.wikipedia.org/wiki/Line_fitting

    Line fitting is the process of constructing a straight line that has the best fit to a series of data points. Several methods exist, considering: Vertical distance: Simple linear regression; Resistance to outliers: Robust simple linear regression
