Function Documentation

void vl_slic_segment	(	vl_uint32 *	segmentation,
		float const *	image,
		vl_size	width,
		vl_size	height,
		vl_size	numChannels,
		vl_size	regionSize,
		float	regularization,
		vl_size	minRegionSize
	)

SLIC superpixel segmentation.

Parameters:

segmentation	segmentation.
image	image to segment.
width	image width.
height	image height.
numChannels	number of image channels (depth).
regionSize	nominal size of the regions.
regularization	trade-off between appearance and spatial terms.
minRegionSize	minimum size of a segment.

The function computes the SLIC superpixels of the specified image image. image is a pointer to an width by height by by numChannles array of float. segmentation is a pointer to a width by height array of vl_uint32. segmentation contain the labels of each image pixels, from 0 to the number of regions minus one.
