Calculates the per-element bit-wise disjunction of two arrays or an array and a scalar

dst = cv.bitwise_or(src1, src2)
dst = cv.bitwise_or(src1, src2, 'OptionName', optionValue, ...)

Input

• src1 first input array or a scalar.
• src2 second input array or a scalar. In case both are array, they must have the same size and type.

Output

• dst output array that has the same size and type as the input arrays.

Options

• Mask optional operation mask, 8-bit single channel array, that specifies elements of the output array to be changed. Not set by default.
• Dest Used to initialize the output dst when a mask is used. Not set by default.

The function calculates the per-element bit-wise logical disjunction for:

• Two arrays when src1 and src2 have the same size:

  dst(I) = src1(I) OR src2(I) if mask(I) != 0
  

• An array and a scalar when src2 is constructed from Scalar or has the same number of elements as size(src1,3):

  dst(I) = src1(I) OR src2 if mask(I) != 0
  

• A scalar and an array when src1 is constructed from Scalar or has the same number of elements as size(src2,3):

  dst(I) = src1 OR src2(I) if mask(I) != 0
  

In case of floating-point arrays, their machine-specific bit representations (usually IEEE754-compliant) are used for the operation. In case of multi-channel arrays, each channel is processed independently. In the second and third cases above, the scalar is first converted to the array type.
