compute method
Compute computes hash of the input image using BlockMeanHash.

Implementation
@override
Mat compute(InputArray inputArr, [OutputArray? outputArr]) {
final p = outputArr?.ptr ?? calloc<cvg.Mat>();
cvRun(() => cffi.BlockMeanHash_Compute(ref, inputArr.ref, p));
return outputArr ?? Mat.fromPointer(p);
