String Mat hing with Gaps for Musi al Melodi Re
نویسنده
چکیده
Abstra t. Here, we have designed and implemented algorithms for string mat hing with gaps for musi al melodi re ognition on polyphoni musi using bit-wise operations. Musi analysts are often on erned with nding o urren es of patterns (motifs), or repetitions of the same pattern, possibly with variations, in a s ore. An important example of exibility required in s ore sear hing arises from the nature of polyphoni musi . Within a ertain time span ea h of the simultaneously-performed voi es in a musi al omposition does not, typi ally, ontain the same number of notes. So `melodi events' o urring in one voi e may be separated from their neighbours in a s ore by intervening events in other voi es. Sin e we annot generally rely on voi e information being present in the s ore we need to allow for temporal `gaps' between events in the mat hed pattern.

متن کاملFlexible Musi Retrieval in Sublinear Time
Abstra t. Musi sequen es an be treated as texts in order to perform musi retrieval tasks on them. However, the text sear h problems that result from this modeling are unique to musi retrieval. Up to date, several approa hes derived from lassi al string mat hing have been proposed to ope with the new sear h problems, yet ea h problem had its own algorithms. In this paper we show that a te hnique...
متن کاملA Note on Randomized Algorithm for String Mat hing with Mismat hes
Abstra t. Atallah et al. [ACD01℄ introdu ed a randomized algorithm for string mat hing with mismat hes, whi h utilized fast Fourier transformation (FFT) to ompute onvolution. It estimates the s ore ve tor of mat hes between text string and a pattern string, i.e. the ve tor obtained when the pattern is slid along the text, and the number of mat hes is ounted for ea h position. In this paper, we ...
متن کاملForward - Fast - Sear h : Another Fast Variant of the Boyer - Moore String Mat
Abstra t. We present a variation of the Fast-Sear h string mat hing algorithm, a re ent member of the large family of Boyer-Moore-like algorithms, and we ompare it with some of the most e e tive string mat hing algorithms, su h as Horspool, Qui k Sear h, Tuned Boyer-Moore, Reverse Fa tor, Berry-Ravindran, and Fast-Sear h itself. All algorithms are ompared in terms of run-time e ien y, number of...
