Struct opencv::img_hash::AverageHash

pub struct AverageHash { /* private fields */ }

Computes average hash value of the input image

This is a fast image hashing algorithm, but only work on simple case. For more details, please refer to lookslikeit

Trait Implementations

impl AlgorithmTrait for AverageHash

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 AverageHash

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<()>

Stores algorithm parameters in a file storage

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

@deprecated

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 AverageHashTrait for AverageHash

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

impl AverageHashTraitConst for AverageHash

fn as_raw_AverageHash(&self) -> *const c_void

impl Boxed for AverageHash

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

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer

impl Debug for AverageHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for AverageHash

fn drop(&mut self)

Executes the destructor for this type.

impl From<AverageHash> for Algorithm

fn from(s: AverageHash) -> Self

Converts to this type from the input type.

impl From<AverageHash> for ImgHashBase

fn from(s: AverageHash) -> Self

Converts to this type from the input type.

impl ImgHashBaseTrait for AverageHash

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

fn compute( &mut self, input_arr: &impl ToInputArray, output_arr: &mut impl ToOutputArray ) -> Result<()>

Computes hash of the input image

impl ImgHashBaseTraitConst for AverageHash

fn as_raw_ImgHashBase(&self) -> *const c_void

fn compare( &self, hash_one: &impl ToInputArray, hash_two: &impl ToInputArray ) -> Result<f64>

Compare the hash value between inOne and inTwo
