Struct opencv::img_hash::BlockMeanHash

pub struct BlockMeanHash { /* fields omitted */ }

Image hash based on block mean.

See zauner2010implementation for details.

Methods

impl BlockMeanHash

pub fn as_raw_BlockMeanHash(&self) -> *mut c_void

pub unsafe fn from_raw_ptr(ptr: *mut c_void) -> Self

impl BlockMeanHash

pub fn set_mode(&mut self, mode: i32) -> Result<()>

Create BlockMeanHash object

Parameters

• mode: the mode

pub fn get_mean(&self) -> Result<VectorOfdouble>

pub fn create(mode: i32) -> Result<PtrOfBlockMeanHash>

C++ default parameters

• mode: BLOCK_MEAN_HASH_MODE_0

Trait Implementations

impl AlgorithmTrait for BlockMeanHash

fn as_raw_Algorithm(&self) -> *mut c_void

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

Clears the algorithm state

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

Stores algorithm parameters in a file storage

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

simplified API for language bindings

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

Reads algorithm parameters from a file storage

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.

impl Drop for BlockMeanHash

fn drop(&mut self)

Executes the destructor for this type.
