Subsampling

Specifies the subsampling factor for images and point maps that are used for model generation and hypothesis search. Specifying subsampling 0.5 will search on images with half the resolution in X and Y directions, compared to the rectified image resolution.

Lower values of subsampling will result in faster runtimes. Higher values will result in better pose hypotheses and, when using 2D refinement Iterations, also a higher 2D localization precision.

Note

When searching for objects with thin geometry using lower subsampling will occasionally provide more results.

Format

Number	It is a positive number between 0 and 1.
Number	The special value 0 indicates that the factor is automatically computed.

Default
