circleFitValidate
Validate (determine) the number of circles for fitting in a 2D dataset
Contents
Syntax
- param=circleFitValidate(data, opt, showPlot)
Description
param=circleFitValidate(data, opt) returns the best parameters for the selected number of circles via cluster validation
- data: 2D data for fitting circles
- opt: Options for validating no. of circles
- opt.circleNumMax: Max no. of circles
- opt.trialNum: No. of trials for circleFit
- opt.errorReductionTh: Error reduction threshold to determine the no. of circles
- opt.interactiveDisplay: 1 for interactive display
- opt.circleFitOpt: options for circleFitOpt
param: The best parameters for the selected number of circles, where each column is the parameters for a circle
Example
im=imread('circleEdge02.png'); [yEdge, xEdge]=find(im); % x and y coordinates of edge data=[xEdge'; yEdge']; opt=circleFitValidate('defaultOpt'); opt.circleNumMax=2; param=circleFitValidate(data, opt, 1);
