[−][src]Trait opencv::hub_prelude::Boost
Required methods
pub fn as_raw_Boost(&self) -> *const c_void
[src]
pub fn as_raw_mut_Boost(&mut self) -> *mut c_void
[src]
Provided methods
pub fn get_boost_type(&self) -> Result<i32>
[src]
Type of the boosting algorithm. See Boost::Types. Default value is Boost::REAL.

setBoostType
pub fn set_boost_type(&mut self, val: i32) -> Result<()>
[src]
Type of the boosting algorithm. See Boost::Types. Default value is Boost::REAL.

pub fn get_weak_count(&self) -> Result<i32>
[src]
pub fn set_weak_count(&mut self, val: i32) -> Result<()>
[src]
pub fn get_weight_trim_rate(&self) -> Result<f64>
[src]
A threshold between 0 and 1 used to save computational time. Samples with summary weight do not participate in the next iteration of training. Set this parameter to 0 to turn off this functionality. Default value is 0.95.

Implementations
impl<'_> dyn Boost + '_
[src]
pub fn create() -> Result<Ptr<dyn Boost>>
[src]
Creates the empty model. Use StatModel::train to train the model, Algorithm::load<Boost>(filename) to load the pre-trained model.
pub fn load(filepath: &str, node_name: &str) -> Result<Ptr<dyn Boost>>
[src]
Loads and creates a serialized Boost from a file
Use Boost::save to serialize and store an RTree to disk. Load the Boost from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier
Parameters
- filepath: path to serialized Boost
- nodeName: name of node containing the classifier
C++ default parameters
- node_name: String()
