Struct opencv::quality::QualityMSE

pub struct QualityMSE { /* fields omitted */ }

Full reference mean square error algorithm https://en.wikipedia.org/wiki/Mean_squared_error

Implementations

impl QualityMSE

pub fn create(ref_: &dyn ToInputArray) -> Result<Ptr<QualityMSE>>

Create an object which calculates quality

Parameters

• ref: input image to use as the reference for comparison

pub fn compute(
    ref_: &dyn ToInputArray,
    cmp: &dyn ToInputArray,
    quality_map: &mut dyn ToOutputArray
) -> Result<Scalar>

static method for computing quality

Parameters

• ref: reference image
• cmp: comparison image=
• qualityMap: output quality map, or cv::noArray()

Returns

cv::Scalar with per-channel quality values. Values range from 0 (best) to max float (worst)

Trait Implementations

impl AlgorithmTrait for QualityMSE

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 QualityMSE

fn as_raw_Algorithm(&self) -> *const c_void

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 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 Boxed for QualityMSE

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 Drop for QualityMSE

fn drop(&mut self)

Executes the destructor for this type.

impl From<QualityMSE> for Algorithm

fn from(s: QualityMSE) -> Self

impl QualityBase for QualityMSE

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

fn compute(&mut self, img: &dyn ToInputArray) -> Result<Scalar>
