Speaker Diarization Using Improved SincNet Models to Extract Speaker Embeddings
(University of Waterloo, 2021-10-25)Speaker diarization is the process of identifying who spoke when in an audio stream, and it is applied in many fields, such as information retrieval and psychotherapy. Speaker embeddings extraction is a crucial step in any ... -
Specifying User Preferences for Autonomous Robots through Interactive Learning
(University of Waterloo, 2020-09-28)This thesis studies a central problem in human-robot interaction (HRI): How can non-expert users specify complex behaviours for autonomous robots? A common technique for robot task specification that does not require ... -
Speckle Noise Reduction via Homomorphic Elliptical Threshold Rotations in the Complex Wavelet Domain
(University of Waterloo, 2005)Many clinicians regard speckle noise as an undesirable artifact in ultrasound images masking the underlying pathology within a patient. Speckle noise is a random interference pattern formed by coherent radiation in a ... -
Spectrum and Energy Efficient Medium Access Control for Wireless Ad Hoc Networks
(University of Waterloo, 2016-05-11)The increasingly growing number of mobile devices and volume of mobile data traffic necessitate establishing an effective self-organizing wireless ad hoc network to efficiently utilize radio spectrum and energy. The ... -
Spectrum Sensing in Cognitive Radio: Multi-detection Techniques based Model
(University of Waterloo, 2012-12-19)Cognitive radio (CR) paradigm is a new radio technology proposed to solve spectrum scarcity and underutilization. Central to CR is spectrum sensing (SS), which is responsible for detecting unoccupied frequencies. Since ... -
Speech Endpoint Detection: An Image Segmentation Approach
(University of Waterloo, 2013-04-26)Speech Endpoint Detection, also known as Speech Segmentation, is an unsolved problem in speech processing that affects numerous applications including robust speech recognition. This task is not as trivial as it appears, ... -
