Detailed Description

A class that defines a single blob within an image.

Constructor & Destructor Documentation

rdf::Blob::Blob

(

)

Initializes a new instance of the Blob class.

rdf::Blob::Blob	(	const QVector< cv::Point > &	outerC,
		const QVector< QVector< cv::Point > > &	innerC
	)

Initializes a new instance of the Blob class.

Parameters

outerC	The outer contour of the blob.
innerC	The inner contours of the blob (can be more than one).

Member Function Documentation

float rdf::Blob::blobOrientation

(

)

const

The blobs orientation based on moments.

Returns

The orientation of the blob in rad.

bool rdf::Blob::drawBlob	(	cv::Mat &	imgSrc,
		cv::Scalar	color = cv::Scalar(255, 255, 255),
		int	maxLevel = 1
	)		const

Draws the Blob.

Parameters

imgSrc	The img source where the blob is drawn.
color	The color of the blob.

Returns

True if the blob is drawn.
