Description
The operator info_smooth info_smooth InfoSmooth InfoSmooth InfoSmooth info_smooth smooth_image smooth_image SmoothImage SmoothImage SmoothImage smooth_image Filter Filter Filter Filter filter filter Alpha Alpha Alpha Alpha alpha alpha smooth_image smooth_image SmoothImage SmoothImage SmoothImage smooth_image Filter Filter Filter Filter filter filter
'deriche1', 'deriche2', 'shen' and 'gauss'.
The gauss filter was conventionally implemented with filter masks
(the other three are recursive filters). In the case of the gauss
filter the filter coefficients (of the one-dimensional impulse
answer
Coeffs Coeffs Coeffs Coeffs coeffs coeffs
For an explanation of the concept of smoothing filters see the introduction
of chapter Filters / Smoothing .
Attention
Note that filter operators may return unexpected results if
an image with a reduced domain is used as input. Please refer to the
chapter Filters .
Execution Information
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.
Parameters
Filter Filter Filter Filter filter filter string → HTuple str HTuple Htuple (string) (string ) (HString ) (char* )
Name of required filter.
Default value:
'deriche2'
"deriche2"
"deriche2"
"deriche2"
"deriche2"
"deriche2"
List of values: 'deriche1' "deriche1" "deriche1" "deriche1" "deriche1" "deriche1" , 'deriche2' "deriche2" "deriche2" "deriche2" "deriche2" "deriche2" , 'gauss' "gauss" "gauss" "gauss" "gauss" "gauss" , 'shen' "shen" "shen" "shen" "shen" "shen"
Alpha Alpha Alpha Alpha alpha alpha real → HTuple float HTuple Htuple (real) (double ) (double ) (double )
Filter parameter: small values effect strong
smoothing (reversed in case of 'gauss').
Default value: 0.5
Suggested values: 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 7.0, 10.0
Minimum increment: 0.01
Recommended increment: 0.1
Restriction: Alpha > 0.0
Size Size Size Size size size integer → HTuple int HTuple Htuple (integer) (int / long) (Hlong ) (Hlong )
Width of filter is approx. size x size pixels.
Coeffs Coeffs Coeffs Coeffs coeffs coeffs integer-array → HTuple Sequence[int] HTuple Htuple (integer) (int / long) (Hlong ) (Hlong )
In case of gauss filter: coefficients of the “positive”
half of the 1D impulse answer.
Example (HDevelop)
info_smooth('deriche2',0.5,Size,Coeffs)
smooth_image(Input,Smooth,'deriche2',7)
Example (C)
info_smooth('deriche2',0.5,Size,Coeffs);
smooth_image(Input,&Smooth,'deriche2',7);
Example (HDevelop)
info_smooth('deriche2',0.5,Size,Coeffs)
smooth_image(Input,Smooth,'deriche2',7)
Example (HDevelop)
info_smooth('deriche2',0.5,Size,Coeffs)
smooth_image(Input,Smooth,'deriche2',7)
Example (HDevelop)
info_smooth('deriche2',0.5,Size,Coeffs)
smooth_image(Input,Smooth,'deriche2',7)
Result
If the parameter values are correct the operator
info_smooth info_smooth InfoSmooth InfoSmooth InfoSmooth info_smooth 2 (H_MSG_TRUE ). Otherwise an
exception is raised.
