Calculates the per-element absolute difference between two arrays or between an array and a scalar

dst = cv.absdiff(src1, src2)

Input

• src1 first input array or a scalar.
• src2 second input array or a scalar.

Output

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

The function cv.absdiff calculates:

• Absolute difference between two arrays when they have the same size and type:

  dst(I) = saturate(|src1(I) - src2(I)|)
  

• Absolute difference between an array and a scalar when the second array is constructed from Scalar or has as many elements as the number of channels in src1:

  dst(I) = saturate(|src1(I) - src2|)
  

• Absolute difference between a scalar and an array when the first array is constructed from Scalar or has as many elements as the number of channels in src2:

  dst(I) = saturate(|src1 - src2(I)|)
  

where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently.

Note: Saturation is not applied when the arrays have the depth int32. You may even get a negative value in the case of overflow.
