[in]	imIn	: input image
[out]	imOut	: output image
[in]	exponent	: exponent to raise the value of each pixel

Note

Output value is limited to the maximum value of imOut data type

◆ sqrt()

RES_T smil::sqrt	(	const Image< T1 > &	imIn,
		Image< T2 > &	imOut
	)

sqrt() - square root of an image

The result is a image where the value of each pixel will be given by :

imOut(x) = sqrt(imIn(x)

Parameters

[in]	imIn	: input image
[out]	imOut	: output image
