bit_xor — Bit-by-bit XOR of all pixels of the input images.
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.
Input image(s) 1.
Input image(s) 2.
Result image(s) by XOR-operation.
read_image(Image1,'fabrik') dev_display (Image1) read_image(Image2,'monkey') dev_display (Image2) bit_xor(Image1,Image2,ImageBitXor) dev_display (ImageBitXor)
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.
