Mutable methods for crate::objdetect::HOGDescriptor

Required Methods

fn as_raw_mut_HOGDescriptor(&mut self) -> *mut c_void

Provided Methods

fn set_win_size(&mut self, val: Size)

Detection window size. Align to block size and block stride. Default value is Size(64,128).

fn set_block_size(&mut self, val: Size)

Block size in pixels. Align to cell size. Default value is Size(16,16).

fn set_block_stride(&mut self, val: Size)

Block stride. It must be a multiple of cell size. Default value is Size(8,8).

fn set_cell_size(&mut self, val: Size)

Cell size. Default value is Size(8,8).

fn set_nbins(&mut self, val: i32)

Number of bins used in the calculation of histogram of gradients. Default value is 9.

fn set_deriv_aperture(&mut self, val: i32)

not documented

fn set_win_sigma(&mut self, val: f64)

Gaussian smoothing window parameter.

fn set_histogram_norm_type(&mut self, val: HOGDescriptor_HistogramNormType)

histogramNormType

fn set_l2_hys_threshold(&mut self, val: f64)

L2-Hys normalization method shrinkage.

fn set_gamma_correction(&mut self, val: bool)

Flag to specify whether the gamma correction preprocessing is required or not.

fn set_svm_detector(&mut self, val: Vector<f32>)

coefficients for the linear SVM classifier.

fn set_ocl_svm_detector(&mut self, val: UMat)

coefficients for the linear SVM classifier used when OpenCL is enabled

fn set_free_coef(&mut self, val: f32)

not documented

fn set_nlevels(&mut self, val: i32)

Maximum number of detection window increases. Default value is 64

fn set_signed_gradient(&mut self, val: bool)

Indicates signed gradient will be used or not

fn set_svm_detector_input_array( &mut self, svmdetector: &impl ToInputArray, ) -> Result<()>

@example samples/cpp/peopledetect.cpp / Sets coefficients for the linear SVM classifier.

Parameters

• svmdetector: coefficients for the linear SVM classifier.

fn read(&mut self, fn_: &mut impl FileNodeTrait) -> Result<bool>

Reads HOGDescriptor parameters and coefficients for the linear SVM classifier from a file node.

Parameters

• fn: File node

fn load(&mut self, filename: &str, objname: &str) -> Result<bool>

loads HOGDescriptor parameters and coefficients for the linear SVM classifier from a file

Parameters

• filename: Name of the file to read.
• objname: The optional name of the node to read (if empty, the first top-level node will be used).

C++ default parameters

• objname: String()

fn load_def(&mut self, filename: &str) -> Result<bool>

loads HOGDescriptor parameters and coefficients for the linear SVM classifier from a file

Parameters

• filename: Name of the file to read.
• objname: The optional name of the node to read (if empty, the first top-level node will be used).

Note

This alternative version of HOGDescriptorTrait::load function uses the following default values for its arguments:

• objname: String()

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
