Methods
-
compare(
InputArray hashOne, InputArray hashTwo) → double -
Compare compares the hash value between a and b using BlockMeanHash.
override
-
compareAsync(
InputArray hashOne, InputArray hashTwo) → Future< double> -
override
-
compute(
InputArray inputArr, [OutputArray? outputArr]) → Mat -
Compute computes hash of the input image using BlockMeanHash.
override
-
computeAsync(
InputArray inputArr, [OutputArray? outputArr]) → Future< Mat> -
override
-
dispose(
) → void -
Releases the underlying native resources. Idempotent: calling it more
than once is safe, but the object must not be used after dispose.
inherited
-
freeNative(
) → void -
Frees the native resources owned by this object. Subclasses implement the
concrete free logic here; callers must use dispose instead.
override
-
getMean(
) → VecF64 - https://docs.opencv.org/4.x/df/d55/classcv_1_1img__hash_1_1BlockMeanHash.html#ad5aef85f58315551cac14bcabe05f0c3
-
getMeanAsync(
) → Future< VecF64> -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
