Class CVErodeBlock

Namespace
VisioForge.Core.MediaBlocks.OpenCV
Assembly
VisioForge.Core.dll

OpenCV erode block for morphological image processing operations. This block performs erosion, a fundamental morphological operation that shrinks white regions (foreground objects) in binary or grayscale images. Erosion is commonly used for noise removal, thin line detection, separating connected objects, and removing small artifacts. The operation uses a structuring element (kernel) that defines the shape and size of the erosion. Often paired with dilation for opening/closing operations in computer vision preprocessing. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

CVErodeBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.OpenCV.CVErodeBlock class. Creates a morphological erosion block with default kernel settings.

public CVErodeBlock()

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 erode 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 erode block.

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Type

Gets the media block type identifier.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the OpenCV erode element within the pipeline. This method creates the erode filter with default morphological settings, establishes input and output pads, and prepares the block for image processing.

public override bool Build()

Returns

bool

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

CleanUp()

Releases all resources and performs cleanup operations for this OpenCV erode block. This method disposes of the erode 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 erode element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the erode functionality.

GetElement()

Gets the underlying GStreamer element that performs the erode operation.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the OpenCV erode 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 morphological operations support.

public static bool IsAvailable()

Returns

bool

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

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this OpenCV erode 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.
