add__ ( Image1, Image2 : ImageResult : Mult, Add : )
Add two images.
The operator add__ adds two images. The gray values
(g1,g2) of the input images (Image1 and
Image2) are transformed as follows:
g' := (g1 + g2) * Mult + Add
Parameters
Image1 (input_object)
|
image(-array) -> object : byte / int1 / int2 / int4 / real / direction / cyclic / complex
|
Image 1 |
Image2 (input_object)
|
image(-array) -> object : byte / int1 / int2 / int4 / real / direction / cyclic / complex
|
Image 2 |
ImageResult (output_object)
|
image(-array) -> object : byte / int1 / int2 / int4 / real / direction / cyclic / complex
|
Result of the addition. |
Mult (input_control)
|
number -> real / integer
|
Factor for gray value adaption. |
Default value: 0.5 |
Suggested values: 0.2, 0.4, 0.6, 0.8, 1.0, 1.5, 2.0, 3.0, 5.0 |
Range of values: -255.0 <= Mult <= 255.0 |
Minimum increment: 0.001
|
Recommended increment: 0.1
|
Add (input_control)
|
number -> real / integer
|
Value for gray value range adaption. |
Default value: 0 |
Suggested values: 0, 64, 128, 255, 512 |
Range of values: -512.0 <= Add <= 512.0 |
Minimum increment: 0.01
|
Recommended increment: 1.0
|
Example
read_image(:Image0:"fabrik":)>
disp_image(Image0:::)>
read_image(:Image1:"Affe":)>
disp_image(Image1:::)>
add__(Image0,Image1:Result:2.0,10.0:)>
disp_image(Result:::)>
Result
The operator add__ returns the value TRUE if the
parameters are correct. The behavior in case of empty input (no
input images available) is set via the operator
set_system(::'no_object_result',<Result>:)
If necessary an exception is raised.
