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

Trait Implementations

impl AlgorithmTrait for PtrOfAverageHash

fn as_raw_Algorithm(&self) -> *const c_void

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

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

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 AverageHashTrait for PtrOfAverageHash

fn as_raw_AverageHash(&self) -> *const c_void

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

impl ImgHashBaseTrait for PtrOfAverageHash

fn as_raw_ImgHashBase(&self) -> *const c_void

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

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

Computes hash of the input image

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

Compare the hash value between inOne and inTwo
