WebDescription. The operator lines_facet can be used to extract lines (curvilinear structures) from the image Image.The extracted lines are returned in Lines as subpixel precise XLD-contours. The parameter LightDark determines, whether bright or dark lines are extracted.. The extraction is done by using the facet model, i.e., a least squares fit, to determine the … WebApr 12, 2024 · Fit parameters and standard deviations. a = 0.509 ± 0.017. b = 0.499 ± 0.002. We see that both fit parameters are very close to our input values of a = 0.5 and b = 0.5 so the curve_fit function converged to the …

WebMastering them makes application development much more fun. In essence filters calculate a value based on the intensity of a certain neighborhood of pixels. The size of that neighborhood can be adjusted, and in HALCON this is typically done through parameters like MaskWidth/MaskHeight, Sigma or Alpha.
