  1. 1. Semantic segmentation using convolutional neural networks to facilitate motion tracking of feet : For real-time analysis of perioperative microcirculation images in patients with critical limb thretening ischemia

    University essay from Linköpings universitet/Avdelningen för medicinsk teknik

    Author : Andreas Öberg; Martin Hulterström; [2021]
    Keywords : semantic segmentation; convolutional neural network; critical limb threatening ischemia; ROI tracking; deep learning;

    Abstract : This thesis investigates the use of Convolutional Neural Networks (CNNs) toperform semantic segmentation of feet during endovascular surgery in patientswith Critical Limb Threatening Ischemia (CLTI). It is currently being investigatedwhether objective assessment of perfusion can aid surgeons during endovascularsurgery. READ MORE

  2. 2. Insights on Creating a Growth Machine Using Attribution Modelling

    University essay from KTH/Optimeringslära och systemteori

    Author : Hannes Kindbom; Viktor Reineck; [2021]
    Keywords : Digital marketing; Attribution modelling; Last-touch attribution; Multi-touch attribution; Simple probabilistic; Logistic regression; Digital marknadsföring; Attributionsmodellering; Last-touch attribution; Multi-touch attribution; Simpel probabilistisk; Logistisk regression;

    Abstract : Given access to detailed tracking data, the problem of attribution modelling has recently gained attention in both academia and the industry. Being able to determine the influence of each marketing channel in driving conversions can help advertisers to allocate their marketing budgets accordingly and ultimately increase their customer base and achieve a higher Return On Investment (ROI).

  3. 3. Region Proposal Based Object Detectors Integrated With an Extended Kalman Filter for a Robust Detect-Tracking Algorithm

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Gabriel Khajo; [2019]
    Keywords : Object Detection; Extended Kalman Filter; Tracking;

    Abstract : In this thesis we present a detect-tracking algorithm (see figure 3.1) that combines the detection robustness of static region proposal based object detectors, like the faster region convolutional neural network (R-CNN) and the region-based fully convolutional networks (R-FCN) model, with the tracking prediction strength of extended Kalman filters, by using, what we have called, a translating and non-rigid user input region of interest (RoI-) mapping.
