Struct opencv::flann::AutotunedIndexParams

pub struct AutotunedIndexParams { /* private fields */ }

Implementations

impl AutotunedIndexParams

pub fn new( target_precision: f32, build_weight: f32, memory_weight: f32, sample_fraction: f32 ) -> Result<AutotunedIndexParams>

C++ default parameters

• target_precision: 0.8f
• build_weight: 0.01f
• memory_weight: 0
• sample_fraction: 0.1f

pub fn new_def() -> Result<AutotunedIndexParams>

Note

This alternative version of [new] function uses the following default values for its arguments:

• target_precision: 0.8f
• build_weight: 0.01f
• memory_weight: 0
• sample_fraction: 0.1f
