Cascading is a particular case of ensemble learning based on the concatenation of several classifiers, using all information collected from the output from a given classifier as additional information for the next classifier in the cascade. Unlike voting or stacking ensembles, which are multiexpert systems, cascading is a multistage one.
A publication by Papageorgiou et al. [2] discussed working with an alternate feature set based on Haar wavelets instead of the usual image intensities. Paul Viola and Michael Jones [1] adapted the idea of using Haar wavelets and developed the so-called Haar-like features. A Haar-like feature considers adjacent rectangular regions at a specific ...
The Haar features used in the Viola-Jones algorithm are a subset of the more general Haar basis functions, which have been used previously in the realm of image-based object detection. [ 4 ] While crude compared to alternatives such as steerable filters , Haar features are sufficiently complex to match features of typical human faces.

Another class of eye music is when the score is purposely made difficult for the performer. [1] For example, in Benedetto Marcello's cantata Stravaganze d’amore, the continuo part is written entirely in enharmonic chords, that is, "puns" of chord indications spelled with no regard to the key of the rest of the ensemble, but (in equal temperament) indistinguishable audibly from those spelled ...
An XML Schema Definition (XSD) implementation of Version 2.0 was released in September 2008. Version 3.0 was released in August 2011 with improved virtual instrument support, in both DTD and XSD versions. [12] [13] Version 3.1 was released in December 2017 with improved support for the Standard Music Font Layout . [14]
The Haar sequence is now recognised as the first known wavelet basis and is extensively used as a teaching example. The Haar sequence was proposed in 1909 by Alfréd Haar. [1] Haar used these functions to give an example of an orthonormal system for the space of square-integrable functions on the unit interval [0, 1]. The study of wavelets, and ...
Along with free software and Linux (a free operating system), copyleft licenses, the explosion of the Web and rise of P2P, the cementing of mp3 as a compression standard for recordings, and despite the efforts of the music industry, free music became largely the reality in the early 21st century.
