Perceptual hash functions provide a tool for fast and reliable identification of content. We present new audio hash functions based on summarization of the time-frequency spectral characteristics of an audio document. The proposed hash functions are based on the periodicity series of the fundamental frequency and on singular-value description of the …

A perceptual hash is essentially a fingerprint of an image, audio or video signal such that two perceptually similar signals can be represented by the same fingerprint. Fingerprints can be efficiently compared to determine their degree of similarity. Perceptual Hashing is useful for duplicate or similarity detection and is useful to provide a ...

Perceptual Hashing. Wednesday, May 28th, 2014. Hash functions are an essential mathematical tool that are used to translate data of arbitrary size into a fixed sized output. There are many different kinds of these functions, each with their own characteristics and purpose. For example, cryptographic hash functions can be used to map sensitive ...
