Provided methods

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
