cvSobel

Module:	OpenCV

Calculates the first, second, third or mixed image derivatives using an extended Sobel operator.

Name	Type	Description
inSrc	Image	Source image.
inDDepth	Integer *	Destination image depth.
inXOrder	Integer	Order of the derivative x.
inYOrder	Integer	Order of the derivative y.
inKSize	Integer	Size of the extended Sobel kernel. It must be 1, 3, 5, or 7.
inScale	Real	Scale factor for the computed derivative values.
inDelta	Real	Delta value that is added to the results prior to storing them in dst.
inBorderType	CvBorderType	Pixel extrapolation method.
outDst	Image	Output image.

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type	Description
DomainError	inKSize must be 1, 3, 5 or 7 in cvSobel.
DomainError	Input image must have pixel type different from Int8 and Int32 in cvSobel.
DomainError	Input image must not be empty in cvSobel.

This filter is available on Basic Complexity Level.
