Detailed Description

Sequence face landmarks utility functions.

Function Documentation

cv::Rect fvs::getFaceBBoxFromSegmentation	(	const cv::Mat &	seg,
		bool	square
	)

Get face bounding box from segmentation.

Parameters

seg	The segmentation.
square	Make the bounding box square (limited to segmentation boundaries).

void fvs::renderBoundaries	(	cv::Mat &	img,
		int	hierarchy_level,
		const segmentation::SegmentationDesc &	desc,
		const segmentation::Hierarchy *	seg_hier,
		const cv::Scalar &	color = cv::Scalar(255, 255, 255)
	)

Render the boundaries of the segmentation regions.

Parameters

img	The image that boundaries will be rendered on. The level of the hierarchy. 0 denotes the over-segmentation. >= 1 : denotes a hierarchical level. The segmentation descriptor which contains the segmentations data. The hierarchy information. Boundaries color.

void fvs::renderSegmentationBlend	(	cv::Mat &	img,
		const cv::Mat &	seg,
		float	alpha = 0.5f,
		const cv::Scalar &	full_color = cv::Scalar(0, 0, 255),
		const cv::Scalar &	intersection_color = cv::Scalar(255, 0, 0)
	)

Render segmentation blended with image.

Parameters

img

The image that the segmentation will be blended with. The segmentation as an 8-bit image. Values of 255 denote full regions and values of 128 denote intersection regions. Blending weight [0, 1]. 0 means completely transparent and 1 means completely opaque. The color to be used for full regions. The color to be used for intersection regions.
