int Digikam::Haar::Calculator::calcHaar	(	ImageData *	data,
		SignatureData *	sigData
	)

Determines a total of NUM_COEFS positions in the image that have the largest magnitude (absolute value) in color value.

Returns linearized coordinates in sig1, sig2, and sig3. avgl are the [0,0] values. The order of occurrence of the coordinates in sig doesn't matter. Complexity is 3 x NUM_PIXELS^2 x 2log(NUM_COEFS).

void Digikam::Haar::Calculator::transform ( ImageData * data )

Do the Haar tensorial 2d transform itself.

Here input is RGB data [0..255] in Unit arrays. Results are available in a, b, and c. Fully inplace calculation; order of result is interleaved though, but we don't care about that.
