TonemapMantiuk Class

This algorithm transforms image to contrast using gradients on all levels of gaussian pyramid, transforms contrast values to HVS response and scales the response. After this the image is reconstructed from new contrast values. For more information see @cite MM06.

The TonemapMantiuk type exposes the following members.

Properties

	Name	Description
	CvPtr	Native pointer of OpenCV structure (Inherited from DisposableCvObject.)
	Empty	Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read (Inherited from Algorithm.)
	Gamma	Gets or sets positive value for gamma correction. Gamma value of 1.0 implies no correction, gamma equal to 2.2f is suitable for most displays. Generally gamma > 1 brightens the image and gamma < 1 darkens it. (Inherited from Tonemap.)
	IsDisposed	Gets a value indicating whether this instance has been disposed. (Inherited from DisposableObject.)
	IsEnabledDispose	Gets or sets a value indicating whether you permit disposing this instance. (Inherited from DisposableObject.)
	Saturation	Gets or sets positive saturation enhancement value. 1.0 preserves saturation, values greater than 1 increase saturation and values less than 1 decrease it.
	Scale	Gets or sets contrast scale factor. HVS response is multiplied by this parameter, thus compressing dynamic range. Values from 0.6 to 0.9 produce best results.

Methods

	Name	Description
	Create	Creates TonemapMantiuk object
	Dispose	Releases the resources (Inherited from DisposableObject.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetDefaultName	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. (Inherited from Algorithm.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Process	Tonemaps image (Inherited from Tonemap.)
	Read	Reads algorithm parameters from a file storage (Inherited from Algorithm.)
	Save	Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage fs). (Inherited from Algorithm.)
	ThrowIfDisposed	If this object is disposed, then ObjectDisposedException is thrown. (Inherited from DisposableObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Write	Stores algorithm parameters in a file storage (Inherited from Algorithm.)
