Class CVSmoothBlock

Namespace

VisioForge.Core.MediaBlocks.OpenCV

Assembly

VisioForge.Core.dll

OpenCV smoothing block for image noise reduction and blur effects. This block applies various smoothing algorithms including Gaussian blur, box filter, bilateral filter, and median blur to reduce noise and soften image details. Essential for preprocessing operations in computer vision pipelines, medical imaging, and artistic effects. Provides configurable kernel sizes, sigma values, and edge preservation options. Commonly used to reduce sensor noise, prepare images for edge detection, or create aesthetic blur effects in video production. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Constructors

CVSmoothBlock(CVSmoothSettings)

Initializes a new instance of the VisioForge.Core.MediaBlocks.OpenCV.CVSmoothBlock class with the specified smoothing settings.

public CVSmoothBlock(CVSmoothSettings settings)

Parameters

settings CVSmoothSettings

The smoothing configuration settings containing algorithm parameters.

Properties

Input

Gets the input pad for connecting video sources to be processed.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads for this smoothing block.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the output pad for connecting to downstream processing blocks.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads for this smoothing block.

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Settings

Gets or sets the smoothing configuration settings. Defines blur algorithms, kernel parameters, and noise reduction options.

public CVSmoothSettings Settings { get; set; }

Property Value

CVSmoothSettings

Type

Methods

Build()

Constructs and initializes the OpenCV smoothing element within the pipeline. This method creates the smoothing filter with the specified algorithm settings, establishes input and output pads, and prepares the block for noise reduction processing.

public override bool Build()

Returns

bool

true if the smoothing element was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this OpenCV smoothing block. This method disposes of the smoothing element and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core BaseElement wrapper that provides additional functionality around the OpenCV smoothing element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the smoothing functionality.

GetElement()

Gets the underlying GStreamer element that performs the smoothing operation.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the OpenCV smoothing filter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project. Checks for OpenCV library availability and smoothing algorithm support.

public static bool IsAvailable()

Returns

bool

true if OpenCV smoothing functionality is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this OpenCV smoothing block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
