Convolution

Zusammenfassung

Performs filtering on the pixel values in an image, which can be used for sharpening an image, blurring an image, detecting edges within an image, or other kernel-based enhancements.

Auswertung

For more information about how this function works, see the Convolution raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
