Struct opencv::xfeatures2d::LUCID

pub struct LUCID { /* private fields */ }

Class implementing the locally uniform comparison image descriptor, described in LUCID

An image descriptor that can be computed very fast, while being about as robust as, for example, SURF or BRIEF.

Note: It requires a color image as input.

Implementations

impl LUCID

pub fn create(lucid_kernel: i32, blur_kernel: i32) -> Result<Ptr<LUCID>>

Parameters

• lucid_kernel: kernel for descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth
• blur_kernel: kernel for blurring image prior to descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth

C++ default parameters

• lucid_kernel: 1
• blur_kernel: 2

pub fn create_def() -> Result<Ptr<LUCID>>

Parameters

• lucid_kernel: kernel for descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth
• blur_kernel: kernel for blurring image prior to descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth

Note

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

• lucid_kernel: 1
• blur_kernel: 2

Trait Implementations

impl AlgorithmTrait for LUCID

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

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn read(&mut self, fn_: &FileNode) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for LUCID

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut FileStorage) -> Result<()>

Stores algorithm parameters in a file storage

fn write_1(&self, fs: &mut FileStorage, name: &str) -> Result<()>

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

@deprecated

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of [write_with_name] function uses the following default values for its arguments:

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
