WebOct 6, 2024 · Contour approximation, which uses the Ramer – Douglas – Peucker (RDP) algorithm, aims to simplify a polyline by reducing its vertices given a threshold value. In layman terms, we take a curve and reduce its number of vertices while retaining the bulk of its shape. For example, take a look at Figure 4. plt line thicknessWebThe Polynomial Approximation with Exponential Kernel (PAEK) method ( PAEK in Python) smooths polygons based on a smoothing tolerance. Each smoothed polygon may have more vertices than its source polygon. The Smoothing Tolerance parameter controls the length of a moving path used in calculating the new vertices. princeton bathtub lowesWebContribute to Nbnbrat/OpenCv development by creating an account on GitHub.
