Fast implementations for perceptual tempo extraction

چکیده
We provide an overview of two algorithms submitted for the Audio Tempo Extraction contest within MIREX 2005: A non-causal Matlab implementation (Davies submission) [4] and a real-time C implementation (Brossier submission) [3]. Both algorithms extract a primary and secondary tempo, associated phase values for each tempo and the relative salience of the slowest tempo. Results indicate that in comparison to other algorithms in the evaluation our approaches placed 9th and 12th out of 13 submissions, and were the two fastest implementations. 1 Non-causal Implementation

A Tempo Extraction Algorithm for Raw Audio Recordings
This paper presents a tempo extraction algorithm for raw, polyphonic audio recordings, assuming that music meter and tempo remain constant throughout the recording. The method was submitted at MIREX 2006, in the context of the Audio Tempo Extraction evaluation task. Our approach is based on the self-similarity analysis of the audio recording and does not assume the presence of percussive instru...
متن کاملEvaluation of Audio Beat Tracking and Music Tempo Extraction Algorithms
This is an extended analysis of eight different algorithms for musical tempo extraction and beat tracking. The algorithms participated in the 2006 Music Information Retrieval Evaluation eXchange (MIREX), where they were evaluated using a set of 140 musical excerpts, each with beats annotated by 40 different listeners. Performance metrics were constructed to measure the algorithms’ abilities to ...
متن کاملImage authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...
متن کاملReal-Time Surface Extraction and Visualization of Medical Images using OpenCL and GPUs
Marching Cubes (MC) is an algorithm that extracts surfaces from volumetric scalar data. It is used extensively in visualization and analysis of medical data from modalities like CT and MR, usually after a 3D segmentation of the structures of interest have been performed. Implementations of MC on CPUs are slow, using several seconds (even minutes) to extract the surface before sending it to the ...
متن کاملMusic Tempo (Speed) Classification
Music tempo (speed) is one of the most important features of a song. With successful classification of the tempo of song, content-based music browsing may utilize this feature and search/recommend songs in the same category of tempo. With some paper survey we noticed that prior works were focused on the numerical tempo value instead of the human perceptual speed of song. We proposed Inter-Onset...
