Class CVDilateBlock

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

OpenCV dilate block for morphological image processing operations. This block performs dilation, a fundamental morphological operation that expands white regions (foreground objects) in binary or grayscale images. Dilation is commonly used for noise removal, object enhancement, filling gaps in contours, and connecting nearby objects. The operation uses a structuring element (kernel) that defines the shape and size of the dilation. Essential for image preprocessing in computer vision applications, medical imaging, and object detection. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

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 dilate 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 dilate element within the pipeline. This method creates the dilate 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 dilate element was successfully built and configured; false if initialization failed.

CleanUp()

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

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the dilate functionality.

GetElement()

Gets the underlying GStreamer element that performs the dilate operation.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the OpenCV dilate 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 dilate functionality is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this OpenCV dilate 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.
