Audio Fingerprint Extraction Using an Adapted Computational Geometry Algorithm
This work presents an adapted version of the Computational Geometry Algorithm (CGA) used for the development of audio-based applications and services. The CGA algorithm analyses an audio stream and produces a unique set of points that can be considered to be the audio data “fingerprint”. It is shown that this fingerprint is coding-independent, a fact that can render the proposed algorithm suita...
متن کاملEfficient Audio Fingerprint Application Verification Using the Adapted Computational Geometry Algorithm
An earlier work of the authors introduced an adapted version of the Computational Geometry Algorithm (CGA) designed to analyse an audio stream and produce a unique coding-independent fingerprint. As the adaptability and the induced calculation load of the proposed algorithm form a key characteristic for multiple applications, our current investigation aims to measure its performance and stabili...
متن کاملA Robust Audio Fingerprint Extraction Algorithm
An Audio fingerprint is a small digest of an audio file computed from its main perceptual properties. Like human fingerprints, Audio fingerprints allows to identify an audio file among a set of candidates but does not allow to retreive any other characteristics of the files. Applications of Audio fingerprint include audio monitoring on broadcast chanels, filtering peer to peer networks, meta da...
متن کاملFingerprint Verification Based on Image Processing Segmentation Using an Onion Algorithm of Computational Geometry
In this study, we applied a digital image processing system using the onion algorithm of Computational geometry to develop fingerprint verification. This method may be characterized as an alternative method to the used minutiae extraction algorithm proposed by Ratha et al. The proposed algorithm is also compared to a well-known commercial verification algorithm that is based on Ratha’s algorith...
