Syntax
Delphi:
property HessianThreshold : Real read FHessianThreshold write SetHessianThreshold;
C++ Builder:
__property double HessianThreshold = { read=FHessianThreshold, write=SetHessianThreshold };
Summary
Specifies the Hessian threshold.
Description
Use this property to specify the Hessian threshold.
Only features with Hessian larger than that are extracted.
Good default value is ~300-500 (can depend on the average local contrast and sharpness of the image).
User can further filter out some features based on their Hessian values and other characteristics.
