Implementations

impl BlockMeanHash

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

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

• mode: BLOCK_MEAN_HASH_MODE_0

Trait Implementations

impl AlgorithmTrait for BlockMeanHash

pub fn as_raw_Algorithm(&self) -> *const c_void

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

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

Clears the algorithm state

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

Stores algorithm parameters in a file storage

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

simplified API for language bindings Stores algorithm parameters in a file storage

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

Reads algorithm parameters from a file storage

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

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

pub 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).

pub 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 BlockMeanHashTrait for BlockMeanHash

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

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

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

Create BlockMeanHash object

pub fn get_mean(&self) -> Result<Vector<f64>>

impl Boxed for BlockMeanHash

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

Wrap the specified raw pointer

pub fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

pub fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer

impl Drop for BlockMeanHash

pub fn drop(&mut self)

Executes the destructor for this type.

impl ImgHashBaseTrait for BlockMeanHash

pub fn as_raw_ImgHashBase(&self) -> *const c_void

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

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

Computes hash of the input image

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

Compare the hash value between inOne and inTwo
