DifferenceOfGaussians

Applies difference of Gaussians on an image, i.e. computes difference of two Gaussian smoothed images.

Name	Type	Range	Description
inImage	Image		Input image
inRoi	Region *		Range of output pixels to be computed
inStdDev	Real	0.0 -	Smoothing standard deviation for the smaller kernel
inStdDevRatio	Real	1.0 -	Defines how many times larger is the second kernel
inKernelRelativeSize	Real	0.0 - 3.0	A multiple of the standard deviation determining the size of the kernel
inScale	Real		Output image scaling factor
outImage	Image		Output image
diagKernelShape	Profile		Middle row of the kernel being used

Emphasizes high-frequency image features such as lines or patches / dots.
