Function Documentation

int Bernoulli	(	unsigned char *	Image,
		int	Width,
		int	Height,
		double	Ratio
	)

Fill inpainting mask with Bernoulli distributed pixel-wise mask.

Parameters

Mask	destination
Width,Height	the mask dimensions
Ratio	masking ratio: probability that a pixel is part of the mask

Definition at line 204 of file randmask.c.

int Dots	(	unsigned char *	Mask,
		int	Width,
		int	Height,
		int	PenRadius
	)

Fill inpainting mask with random dots.

Parameters

Mask	destination
Width,Height	the mask dimensions
PenRadius	the radius of the dots

Returns

1 on success, 0 on failure

Definition at line 180 of file randmask.c.

void RandomText	(	unsigned char *	Mask,
		int	Width,
		int	Height
	)

Fill inpainting mask with random text about TV inpainting.

Parameters

Mask	destination
Width,Height	the mask dimensions

This routine generates a random text from several samples about TV regularized inpainting.

Definition at line 342 of file randmask.c.

int Scribble	(	unsigned char *	Mask,
		int	Width,
		int	Height,
		int	PenRadius
	)

Fill inpainting mask with a random scribble.

Parameters

Mask	destination
Width,Height	the mask dimensions
PenRadius	the radius of the scribble line

Returns

1 on success, 0 on failure

This routine generates a random path and draws it with radius PenRadius. The path is generated several times and the path with the greatest variance is selected.
