Trait Implementations

impl AlgorithmTrait for PtrOfQualityPSNR

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_1(&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 QualityBase for PtrOfQualityPSNR

fn as_raw_QualityBase(&self) -> *const c_void

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 ## Parameters * img: comparison image, or image to evalute for no-reference quality algorithms

fn get_quality_map(&self, dst: &mut dyn ToOutputArray) -> Result<()>

Returns output quality map that was generated during computation, if supported by the algorithm

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

Implements Algorithm::clear()

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

Implements Algorithm::empty()

impl QualityPSNRTrait for PtrOfQualityPSNR

fn as_raw_QualityPSNR(&self) -> *const c_void

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

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

Compute the PSNR ## Parameters * cmp: Comparison image ## Returns Per-channel PSNR value, or std::numeric_limits::infinity() if the MSE between the two images == 0

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

Implements Algorithm::empty()

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

Implements Algorithm::clear()

fn get_max_pixel_value(&self) -> Result<f64>

return the maximum pixel value used for PSNR computation

fn set_max_pixel_value(&mut self, val: f64) -> Result<()>

sets the maximum pixel value used for PSNR computation ## Parameters * val: Maximum pixel value
