Spatial Filter Commands
Spatial Filters compute the luminance at a pixel location by merging the values of neighboring pixels in a particular way. The kind of filter determines the way the values are merged. This type of processing is used for enhancement, of image features, suppression of noise, conversion to other value representations, and other purposes. The term "spatial filter" is used to differential this processing in the spatial domain from filtering in the frequency domain as by using FFT's.

Allows you to specify the weights of a 3x3 filter kernel. |
|
|
Applies a "high pass" sharpening filter. The Strength parameter controls the effect. A setting of 0 performs almost no sharpening. |
|
|
Removes isolated "speckles", or outlying pixel values. This is usually applied to RGB images to remove color channel noise. |
|
|
Applies an unsharp mask sharpening filter. The Properties specify the blurring profile which is subtracted from the image. |

Smooths out small scale deviations in an image by applying a Rectangle Filter. |
