QualitySSIM class

Inheritance

• Object
• CvObject<QualitySSIM>
• ICvStruct<QualitySSIM>
• CvStruct<QualitySSIM>
• QualitySSIM

Constructors

QualitySSIM.create(Mat img)

Create an object which calculates quality.

factory

QualitySSIM.fromPointer(Pointer<QualitySSIM> ptr, [bool attach = true])

Properties

hashCode → int

The hash code for this object.

no setter, inherited

isDisposed → bool

Whether this object has been disposed.

no setter, inherited

props → List<Object?>

no setter, inherited

ptr ↔ Pointer<QualitySSIM>

getter/setter pair, inherited

ref → QualitySSIM

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

compute(Mat cmp) → Scalar

Computes SSIM.

computeAsync(Mat cmp) → Future<Scalar>

async version of compute

dispose() → void

Releases the underlying native resources. Idempotent: calling it more than once is safe, but the object must not be used after dispose.

inherited

freeNative() → void

Frees the native resources owned by this object. Subclasses implement the concrete free logic here; callers must use dispose instead.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Properties

finalizer → NativeFinalizer

Static Methods

compute1(Mat img, Mat cmp, {Mat? qualityMap}) → (Scalar, Mat)

compute1Async(Mat img, Mat cmp, {Mat? qualityMap}) → Future<(Scalar, Mat)>
