Classifying Phonotrauma Severity from Vocal Fold Images with Soft Ordinal Regression
Katie Matton, Purvaja Balaji, Hamzeh Ghasemzadeh +7
Phonotrauma refers to vocal fold tissue damage resulting from exposure to forces during voicing. It occurs on a continuum from mild to severe, and treatment options can vary based…
Experimental Framework for Generating Reliable Ground Truth for Laryngeal Spatial Segmentation Tasks
Hamzeh Ghasemzadeh, David S. Ford, Maria E. Powell +1
Objective: The validity of objective measures derived from high-speed videoendoscopy (HSV) depends, among other factors, on the validity of spatial segmentation. Evaluation of the…
Effects of Recording Condition and Number of Monitored Days on Discriminative Power of the Daily Phonotrauma Index
Hamzeh Ghasemzadeh, Robert E. Hillman, Jarrad H. Van Stan +1
Objective: The Daily Phonotrauma Index (DPI) can quantify pathophysiological mechanisms associated with daily voice use in individuals with phonotraumatic vocal hyperfunction (PVH)…
Toward Generalizable Machine Learning Models in Speech, Language, and Hearing Sciences: Estimating Sample Size and Reducing Overfitting
Hamzeh Ghasemzadeh, Robert E. Hillman, Daryush D. Mehta
This study's first purpose is to provide quantitative evidence that would incentivize researchers to instead use the more robust method of nested cross-validation. The second purpo…
Key management system for WSNs based on hash functions and elliptic curve cryptography
Hamzeh Ghasemzadeh, Ali Payandeh, Mohammad Reza Aref
Due to hostile environment and wireless communication channel, security mechanisms are essential for wireless sensor networks (WSNs). Existence of a pair of shared key is a prerequ…
Calibrated Audio Steganalysis
Hamzeh Ghasemzadeh, Mohammad H. Kayvanrad
Calibration is a common practice in image steganalysis for extracting prominent features. Based on the idea of reembedding, a new set of calibrated features for audio steganalysis…
Multi-layer architecture for efficient steganalysis of Undermp3cover in multi-encoder scenario
Hamzeh Ghasemzadeh
Mp3 is a very popular audio format and hence it can be a good host for carrying hidden messages. Therefore, different steganography methods have been proposed for mp3 hosts. But, c…
Calibrated steganalysis of mp3stego in multi-encoder scenario
Hamzeh Ghasemzadeh
Comparing popularity of mp3 and wave with the amount of works published on each of them shows mp3 steganalysis has not found adequate attention. Furthermore, investigating existing…
A Hybrid DOS-Tolerant PKC-Based Key Management System for WSNs
Hamzeh Ghasemzadeh, Ali Payandeh, Mohammad Reza Aref
Security is a critical and vital task in wireless sensor networks, therefore different key management systems have been proposed, many of which are based on symmetric cryptography.…
Jigsaw Cryptanalysis of Audio Scrambling Systems
Hamzeh Ghasemzadeh, Mehdi Tajik Khass, Hamed Mehrara
Recently it was shown that permutation-only multimedia ciphers can completely be broken in a chosen-plaintext scenario. Apparently, chosen-plaintext scenario models a very resource…
Universal Audio Steganalysis Based on Calibration and Reversed Frequency Resolution of Human Auditory System
Hamzeh Ghasemzadeh, Meisam Khalil Arjmandi
Calibration and higher order statistics (HOS) are standard components of many image steganalysis systems. These techniques have not yet found adequate attention in audio steganalys…
Comprehensive Review of Audio Steganalysis Methods
Hamzeh Ghasemzadeh, Mohammad H. Kayvanrad
Recently, merging signal processing techniques with information security services has found a lot of attention. Steganography and steganalysis are among those trends. Like their co…
