I 'm trying to compute the perceptual hash for an image (Using for example the phash algorithm). I want to compute and save the hash in a database for future comparissons.
The compute method from the PHashImpl class set an cv::OutputArray with the result of the computation (the hash).
Is it posible to convert it into a alphanumeric of numeric representation of the hash?
Like: image -> phash_algrithm -> 8a0303f6df3ec8cd
Am i thinking in the right way or my limited knowledge at the moment of the OpenCv is leading me to the wrong path?
