Operation of multi-reservoir systems is known as complicated and often large-scale optimization problems. The problems, because of broad search space, nonlinear relationships, correlation of several variables, as well as problem uncertainty, are difficult requiring powerful algorithms with specific capabilities to be solved. In the present study a Self-adaptive version of Melody Search algorith...

This thesis studies two problems in music information retrieval: search for a given melody in an audio database, and automatic melody transcription. In both of the problems, the representation of the melody is symbolic, i.e., the melody consists of onset times and pitches of musical notes. In the first part of the thesis we present new algorithms for symbolic melody search. First, we present al...

This extended abstract is for the “Audio Melody Extraction” contest of MIREX2009. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement. Our enhancement algorithm focuses on temp...

This paper introduces a project of advanced system of music retrieval from the Internet. The system uses combination of text search (by author, title and other information about the music file included in id3 tag description or similar for other file types) with more intuitive and novel method of melody search using query by humming. The patterns for storing text and melody information as well ...

This extended abstract is for the “Audio Melody Extraction” evaluation in MIREX2010. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement. Our enhancement algorithm focuses on t...

This paper considers a melody extraction algorithm that estimates the melody in polyphonic audio using the harmonic coded structure (HCS) to model melody in the minimum mean-square-error (MMSE) sense. The HCS is harmonically modulated sinusoids with the amplitudes defined by a set of codewords. The considered algorithm performs melody extraction in two steps: i) pitch-candidate estimation and i...

Melody Search (MS) Algorithm as an innovative improved version of Harmony Search optimization method, with a novel Alternative Improvisation Procedure (AIP) is presented in this paper. MS algorithm mimics performance processes of the group improvisation for finding the best succession of pitches within a melody. Utilizing different player memories and their interactive process, enhances the alg...

This paper describes the design method of a WWW-based melody-retrieval system which takes a sung melody as a search clue and retrieves the music title from a music database of standard MIDI files(SMF) over the Internet. The most important thing in building a melody-retrieval system on the Internet is to achieve both high matching accuracy and quick search. It was, however, quite difficult to si...
