Random sample consensus (RANSAC)
RANSAC( fixedPoints, movingPoints, transformType = "Affine", minNtoFit = 16, maxIterations = 20, errorThreshold = 1, goodProportion = 0.5, lambda = 1e-06, verbose = FALSE )
fixedPoints |
fixed points matrix |
movingPoints |
moving points matrix |
transformType |
Affine, Rigid and Similarity currently supported |
minNtoFit |
the minimum number of data values required to fit the model. |
maxIterations |
the maximum number of iterations allowed in the algorithm |
errorThreshold |
a threshold value for determining when a test data point fits a model. this parameter is set based on the standard deviation in the random subset model. that is, a point fits the model error distribution if it is within the bracket of values between mean error plus or minus sd error times errorThreshold. |
goodProportion |
the fraction of close data values required to assert that a model fits well to data. that is, if equal to 0.5, then one would need 50 points to assert that a model fit is good if the whole dataset contains 100 points. |
lambda |
ridge penalty in zero to one |
verbose |
boolean |
output list contains best fitted model, inliers, outliers
