Local corner smoothing based on deep learning for CNC machine tools [PDF]
Scientific ReportsMost of toolpaths for machining is composed of series of short linear segments (G01 command), which limits the feedrate and machining quality. To generate a smooth machining path, a new optimization strategy is proposed to optimize the toolpath at the ...

Computationally efficient approach to quantify 2D particle morphological descriptors [PDF]
EPJ Web of Conferences, 2021 The macro-scale behavior of granular materials is strongly influenced by grain kinematics. The mobility of the grains in turn is affected by grain morphology which needs to be comprehensively characterized.

Image corner detection method based on multi-scale discrete curvature
Xi'an Gongcheng Daxue xuebao, 2021 The traditional curvature calculation method is sensitive to local changes and noise in the discrete domain, which makes the corner detection accuracy and location deviate.

Smoothed Corners and Scattered Waves [PDF]
SIAM Journal on Scientific Computing, 2016 We introduce an arbitrary order, computationally efficient method to smooth corners on curves in the plane, as well as edges and vertices on surfaces in $\mathbb R^3$. The method is local, only modifying the original surface in a neighborhood of the geometric singularity, and preserves desirable features like convexity and symmetry.

Smoothing images creates corners [PDF]
Image and Vision Computing, 2000 The isophote curvature times the gradient magnitude to some power has been studied in the literature as a measure of cornerness in images. Stability in terms of sampling noise has been proposed by selecting corners at high scale and locating them at fine scale.
