static void kmeans::StormStat::compute	(	const LImage< int > &	img,
		ImageAttr< StormStat > *	tobe_set,
		bool	normalize = true,
		size_t	neighborhood_size = 3
	)			[static]

Computes the texture of this image and sets the ImageAttr passed in.

the ImageAttr<StormStat> passed is replaced.

float kmeans::StormStat::get_val

(

size_t

index

)

const

index should be one of the Statistics enums (< NumFeatures).

static float kmeans::StormStat::get_wt

(

size_t

)

[static]

Returns the weight that should be given to the ith Statistic.

The weights add upto 1.0

(

ImageAttr< StormStat > &

img

)

[static]

Scales all the values such that they lie in the range 0 to 1.

void kmeans::StormStat::set_val	(	size_t	index,
		float	val
	)

index should be one of the Statistics enums (< NumFeatures).
