This structure contains parameters of 1D scanning process that can prevent weaker edges in the vicinity of some strong edges from being detected.

Structure Fields

Type fields and default values (if defined) are described below:

Name Type Default Description
Radius Real* Defines how far the blindness works
Threshold Real 0.5f Defines the fraction of a strong edge magnitude that a weaker edge has to have to be detected
Fuzziness Real 0.0f Makes effective threshold decrease linearly from 'Threshold' at distance 'Radius - Radius * Fuzziness' to zero at distance 'Radius + Radius * Fuzziness'
