cvLaplacian


Calculates the Laplacian of an image.

Name Type Description
inSrc Image Source image.
inDDepth Integer* Desired depth of destination image. The NIL value means that it has the same depth as source image.
inKSize Integer Aperture size used to compute the second-derivative filters. The size must be positive and odd.
inScale Real Scale factor for the computed Laplacian values.
inDelta Real Delta value that is added to the results prior to storing them.
inBorderType CvBorderType Pixel extrapolation method.
outDst Image Output image.

Errors

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 odd and not larger than 31 in cvLaplacian.
DomainError Input image must not be empty in cvLaplacian.
DomainError Type of pixel of input image must be float or UINT8 in cvLaplacian.

Complexity Level

This filter is available on Basic Complexity Level.
