  1. 1. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Alice Fracchia; [2023]
    Keywords : Skin cancer; carcinoma; photoacoustic imaging; ultrasound imaging; machine learning; dimensionality reduction; sandpiles algorithm; active contour; multilayer perception MLP ; convolutional neural networks CNN ; autoencoder; Physics and Astronomy;

    Abstract : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. READ MORE

  3. 2. Combining Acoustic Echo Cancellation and Voice Activity Detection in Social Robotics

    University essay from KTH/Matematik (Avd.)

    Author : Anton Fahlgren; [2019]
    Keywords : ;

    Abstract : This thesis is partly a theoretical introduction to some basic concepts of signal processing such as the Fourier transform, linear time invariant systems and spectral analysis of random signals, both in the continuous and discrete setting. A second part is devoted to theory and applications of echo cancellation and voice activity detection in so called social robotics. READ MORE

    Keywords : Mathematics and Statistics;

    Abstract : Abstract—This article have been written in cooperation with The Swedish Defense Research Agency (FOI). The article proposes a method to calibrate hydrophone positions for improved underwater survailence in The Baltic Sea. READ MORE

  5. 4. Implementation and Evaluation of Spectral Subtraction with Minimum Statistics using WOLA and FFT Modulated Filter Banks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Peddi Srinivas Rao; Vallabhaneni Sreelatha; [2014]
    Keywords : Speech Enhancement; Filter Bank; Spectral Subtraction; Wiener Filtering; PESQ; DFT ; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : In communication system environment speech signal is corrupted due to presence of additive acoustic noise, so with this distortion the effective communication is degraded in terms of the quality and intelligibility of speech. Now present research is going how effectively acoustic noise can be eliminated without affecting the original speech quality, this tends to be our challenging in this current research thesis work.
