Implementations

impl QualityGMSD

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

Create an object which calculates image quality

Parameters

• ref: reference image

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 value. Values range from 0 (worst) to 1 (best)

Trait Implementations

impl AlgorithmTrait for QualityGMSD

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 QualityGMSD

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 QualityGMSD

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 QualityGMSD

fn drop(&mut self)

Executes the destructor for this type.

impl From<QualityGMSD> for Algorithm

fn from(s: QualityGMSD) -> Self

Performs the conversion.

impl QualityBase for QualityGMSD

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

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

Compute quality score per channel with the per-channel score in each element of the resulting cv::Scalar. See specific algorithm for interpreting result scores

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

Implements Algorithm::clear()

impl QualityBaseConst for QualityGMSD
