bit_xor🔗
Short description🔗
bit_xor — Bit-by-bit XOR of all pixels of the input images.
Signature🔗
bit_xor( image Image1, image Image2, out image ImageXor )
Description🔗
The operator bit_xor calculates the “xor”
of all pixels of the input images bit by bit.
The semantics of the “xor” operation corresponds to that of C for the
respective types (signed char, unsigned char, short, unsigned short, int/long).
The images must have the same size and pixel type.
The pixels within the definition range of the image in the first
parameter are processed.
* Several images can be processed in one call. In this case both input parameters contain the same number of images which are then processed in pairs. An output image is generated for every pair.
Execution information🔗
Execution information
-
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
-
Multithreading scope: global (may be called from any thread).
-
Automatically parallelized on domain level.
Parameters🔗
Image1 (input_object) (multichannel-)image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4)
Input image(s) 1.
Image2 (input_object) (multichannel-)image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4)
Input image(s) 2.
ImageXor (output_object) (multichannel-)image(-array) → object (byte / direction / cyclic / int1 / int2 / uint2 / int4)
Result image(s) by XOR-operation.
Example🔗
(HDevelop)
read_image(Image1,'fabrik')
dev_display (Image1)
read_image(Image2,'monkey')
dev_display (Image2)
bit_xor(Image1,Image2,ImageBitXor)
dev_display (ImageBitXor)
read_image(&Image0,"monkey")\;
disp_image(Image0,WindowHandle)\;
read_image(&Image1,"fabrik")\;
disp_image(Image1,WindowHandle)\;
bit_xor(Image0,Image1,&ImageBitX)\;
disp_image(ImageBitX,WindowHandle)\;
Result🔗
If the parameter values are correct the operator bit_xor
returns the value 2 (H_MSG_TRUE).
The behavior in case of empty input (no input images available) can be
determined by the operator
set_system(::'no_object_result',<Result>:)
If necessary an exception is raised.
