  • A fully differential capacitively-coupled high CMRR low-power chopper amplifier for EEG dry electrodes 

    Habibzadeh Tonekabony Shad, Erwin; Molinas Cabrera, Maria Marta; Ytterdal, Trond (Journal article; Peer reviewed, 2020)
    The use of dry electrodes is increasing rapidly. Since their impedance is high, there is a high impedance node at the connecting node between the electrode and amplifier. This leads to absorb powerline signal and high CMRR ...
  • Computer-aided diagnosis system for ulcer detection in wireless capsule endoscopy images 

    Charfi, Said; Ansari, Mohamed El; Balasingham, Ilangko (Journal article; Peer reviewed, 2019)
    Wireless capsule endoscopy (WCE) has revolutionised the diagnosis and treatment of gastrointestinal tract, especially the small intestine which is unreachable by traditional endoscopies. The drawback of the WCE is that it ...
  • Polyp detection and segmentation using Mask R-CNN: Does a deeper feature extractor CNN always perform better?
