Perceptual hash functions aim to imitate human perception by focusing on the types of features that drive human sight and hearing.

For Bitcoin specifically, the hashing algorithm difficulty adjusts up and down depending on how high the hash rate is. This is because creation of new Bitcoin was designed to be controlled over time.
