Methods

compare(InputArray hashOne, InputArray hashTwo) → double

Compare compares the hash value between a and b using RadialVarianceHash. For further information, see: https://docs.opencv.org/master/de/d29/classcv_1_1img__hash_1_1ImgHashBase.html#a444a3e9ec792cf029385809393f84ad5

override

compareAsync(InputArray hashOne, InputArray hashTwo) → Future<double>

override

compute(InputArray inputArr, [OutputArray? outputArr]) → Mat

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

override

computeAsync(InputArray inputArr) → Future<Mat>

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
