|
- Generate a convolution kernel:
|
|
|
|
`pgmkernel {{width}} {{height}} > {{path/to/output.pgm}}`
|
|
|
|
- Generate a quadratic convolution kernel:
|
|
|
|
`pgmkernel {{size}} > {{path/to/output.pgm}}`
|
|
|
|
- Specify the weight of the center in the generated kernel:
|
|
|
|
`pgmkernel {{[-w|-weight]}} {{value}} {{width}} {{height}} > {{path/to/output.pgm}}`
