Fields¶

TKeyPointMethod featsType {featKLT}

Type of the extracted features.

unsigned int patchSize {21}

Size of the patch to extract, or 0 if no patch is desired (default=21).

bool useMask {false}

Whether to use a mask for determining the regions where not to look for keypoints (default=false).

bool addNewFeatures {false}

Whether to add the found features to the input feature list or clear it before adding them (default=false).

bool FIND_SUBPIXEL {true}

Indicates if subpixel accuracy is desired for the extracted points (only applicable to KLT and Harris features)

Methods¶

virtual void loadFromConfigFile(const mrpt::config::CConfigFileBase& source, const std::string& section)

This method load the options from a “.ini”-like file or memory-stored string list.

Only those parameters found in the given “section” and having the same name that the variable are loaded. Those not found in the file will stay with their previous values (usually the default values loaded at initialization). An example of an “.ini” file:

[section]
resolution    = 0.10   // blah blah...
modeSelection = 1      // 0=blah, 1=blah,...
