Class: TVLExtractRobustFeatures

Contents 1 Syntax 1.1 Delphi: 1.2 C++ Builder: 2 Summary 3 Description

Syntax

Delphi:

property HessianThreshold : Real read FHessianThreshold write SetHessianThreshold default 500;

C++ Builder:

__property double HessianThreshold = { read=FHessianThreshold, write=SetHessianThreshold, default=500 };

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.
