%% Biogeography Based Optimization (BBO) Signal Features - Created in 19 Jan 2022 by Seyed Muhammad Hossein Mousavi % This code employs Biogeography Based Optimization BBO evolutionary % algorithm in order to extract audio signal feature. % System takes audio signal from input and extracts 'Energy Entropy' % feature from spatial domain and 'Spectral Centroid' feature from % frequency domain as input and target is 'Short Time Energy' feature from time % domain. BBO algorithm fits the final feature vector based on its nature % and returns evolutionary signal feature. BBO is suitable for this % purpose due to its high speed for multiple signal feature extraction % task. You can use your own audio signal or any other type of signal and play % with parameters depending on your system and the lenght of the signal. % ------------------------------------------------ % Feel free to contact me if you find any problem using the code: % Author: SeyedMuhammadHosseinMousavi % My Email: [e-mail] % My Google Scholar: https://scholar.google.com/citations?user=PtvQvAQAAAAJ&hl=en % My GitHub: https://github.com/SeyedMuhammadHosseinMousavi?tab=repositories % My ORCID: https://orcid.org/0000-0001-6906-2152 % My Scopus: https://www.scopus.com/authid/detail.uri?authorId=57193122985 % My MathWorks: https://www.mathworks.com/matlabcentral/profile/authors/9763916# % my RG: https://www.researchgate.net/profile/Seyed-Mousavi-17 % ------------------------------------------------ % Hope it help you, enjoy the code and wish me luck :)
