compute method

  1. @override
Mat compute(
  1. InputArray inputArr, [
  2. OutputArray? outputArr
])
override

Compute computes hash of the input image using MarrHildrethHash. For further information, see: https://docs.opencv.org/master/de/d29/classcv_1_1img__hash_1_1ImgHashBase.html#ae2d9288db370089dfd8aab85d5e0b0f3
