2015 article

Spectral estimation in highly transient data

Emrani, S., & Krim, H. (2015, August 1). 2015 23rd European Signal Processing Conference (Eusipco), pp. 1721–1725.

By: S. Emrani n & H. Krim n 

topics (OpenAlex): Blind Source Separation Techniques; Speech and Audio Processing; Image and Signal Denoising Methods
TL;DR: A new framework for estimating different frequencies in piece-wise periodic signals with time varying amplitude and phase is proposed through a 3-dimensional delay embedding of the introduced model, which constructs a union of intersecting planes where each plane corresponds to one frequency.

2014 article

Persistent Homology of Delay Embeddings and its Application to Wheeze Detection

Emrani, S., Gentimis, T., & Krim, H. (2014, February 11). IEEE Signal Processing Letters, Vol. 21, pp. 459–463.

By: S. Emrani n, T. Gentimis n & H. Krim n 

author keywords: Algebraic topology algorithms; audio analysis; biomedical signal processing; topological signal analysis
topics (OpenAlex): Topological and Geometric Data Analysis
TL;DR: To discover the proper delay, this work proposes an autocorrelation like (ACL) function of the signals, and applies the introduced topological approach to analyze breathing sound signals for wheeze detection. (via Semantic Scholar)

2014 article

Real time detection of harmonic structure: A case for topological signal analysis

Emrani, S., Chintakunta, H., & Krim, H. (2014, May 1). International Conference on Acoustics Speech and Signal Processing.

By: S. Emrani n, H. Chintakunta n & H. Krim n 

topics (OpenAlex): Music and Audio Processing; Topological and Geometric Data Analysis
TL;DR: Using delay embeddings, the timedomain signal is transformed into a point cloud, whose topology reflects the periodic behavior of the signal, and the Euler characteristic provides for a fast computation of topology of the resulting manifold. (via Semantic Scholar)
