Parameters:

q	quick shift object.

VL_EXPORT VlQS* vl_quickshift_new	(	vl_qs_type const *	image,
		int	height,
		int	width,
		int	channels
	)

Create a quick shift object.

-----------------------------------------------------------------

Parameters:

image	the image.
height	the height (number of rows) of the image.
width	the width (number of columns) of the image.
channels	the number of channels of the image.

Returns:

new quick shift object.

The image is an array of vl_qs_type values with three dimensions (respectively widht, height, and channels). Typically, a color (e.g, RGB) image has three channels. The linear index of a pixel is computed with: channels * width* height + row + height * col.

(

VlQS *

q

)

Create a quick shift objet.

Parameters:

q	quick shift object.
