laws_int4 ( Image : ImageTexture : FilterTypes, FilterSize : )

Filter an image using a Laws texture filter.

laws_int4 applies one or more texture transformations to an image, analogously to laws_byte. The parameter Shift is unnecessary for this filter. The resulting image is of type int4.


Parameters

Image (input_object)
image(-array) -> object : byte
Images to which the texture transformation is to be applied.

ImageTexture (output_object)
image(-array) -> object : int4
Texture images.

FilterTypes (input_control)
string(-array) -> string
Desired filters (name or number).
Default value: 'el'
List of values: 'll', 'le', 'ls', 'lr', 'lw', 'lo', 'el', 'ee', 'es', 'er', 'ew', 'eo', 'sl', 'se', 'ss', 'sr', 'sw', 'so', 'rl', 're', 'rs', 'rr', 'rw', 'ro', 'wl', 'we', 'ws', 'wr', 'ww', 'wo', 'ol', 'oe', 'os', 'or', 'ow', 'oo'

FilterSize (input_control)
integer -> integer
Size of the filter kernel.
Default value: 5
List of values: 3, 5, 7


Result

laws_int4 returns TRUE if all parameters are correct. If the input is empty the behaviour can be set via set_system(::'no_object_result',<Result>:). If necessary, an exception is raised.


Possible Successors

mean__, scale__, convert_image_type__, threshold__


Alternatives
