Public Member Functions inherited from rdf::BaseElement
	BaseElement (const QString &id=QString())
	This class keeps an ID to keep track of transformed elements during a processing chain. You can e.g. generate Pixel elements from MserBlobs. After filtering, processing etc. you can map back to the (pixel accurate) MserBlob using this ID. More...

QVector< Vector2D > rdf::PixelSet::pointSet

(

double

offsetAngle = 0.0

)

const

Returns a point set. The points are sampled along the pixel's ellipses w.r.t the relative angle which is added to the text line orientation. If angle == DBL_MAX or pixel->stats() == NULL, the ellipse centers are sampled instead.

Parameters

offsetAngle

The angle which is added to the pixel's local orientation.

Returns

Polygon rdf::PixelSet::polygon ( const QVector< Vector2D > &  pts ) const

protected

Returns a poly line along the points defined by angle. If maxAngleThr != -1, points are rejected if the cosine of their enclosing angle is smaller than maxAngleThr. e.g. maxAngleThr = 0 would allow polygon changes of up to 90°.

Parameters

angle	The angle for sampling the ellipses.
maxAngleThr	The maximum angle thresh.

Returns

Returns the convex hull of the PixelSet.
