Constructors

PeakSignalToNoiseRatioSettings(float)

Creates a PSNR threshold and ensures Value is valid. Typical valid range is non-negative; 30 dB is a common perceptual threshold.

Declaration
public PeakSignalToNoiseRatioSettings(float value)
Parameters
Type Name Description
float value

PSNR threshold in dB.
Exceptions
Type Condition
ArgumentOutOfRangeException

Thrown when value is negative.

Properties

ColorSpaceHandling

Specifies how luminance calculations should handle different color spaces.

Declaration
public LumaColorSpaceMode ColorSpaceHandling { get; init; }
Property Value
Type Description
LumaColorSpaceMode
Remarks

This property controls whether linear color space images are accepted, and how color space conversions are applied during luminance computation.

LumaCalculations

List of Luma calculations to use when measuring PSNR. Each instance contains calculation for an actual and an expected. Provide this if you want to reuse luma calculations across different comparison algorithms (e.g. PSNR and SSIM).

Declaration
public List<LumaPipelineResult> LumaCalculations { get; init; }
Property Value
Type Description
List<LumaPipelineResult>

Value

Value under which the test constraint fails. Typical values are between 20 and 40, with 30 being the human perceptible threshold.

Declaration
public float Value { get; init; }
Property Value
Type Description
float
