  1. 1. Instance segmentation using 2.5D data

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Jonathan Öhrling; [2023]
    Keywords : instance segmentation; multi-modality; segmentation; multi-modality fusion; CNN; RGBD; ToF; Mask R-CNN; RTMDet; MMDetection; COCO; NYUDepth;

    Abstract : Multi-modality fusion is an area of research that has shown promising results in the domain of 2D and 3D object detection. However, multi-modality fusion methods have largely not been utilized in the domain of instance segmentation. READ MORE

  3. 2. Optimization of an advanced algorithm for bone imaging

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Adam Mrozek; [2022]
    Keywords : osteoporosis; optimization; programming; engineering; X-ray; bone; mineral density; speed; faster; projection; MATLAB; C ; Technology and Engineering;

    Abstract : Fracture risk in osteoporosis is increased and osteoporosis is the most common metabolic bone disease and treatment is expensive. Osteoporosis is diagnosed by measuring Bone Mineral Density (BMD), which does not consider other factors such as bone geometry or architecture. READ MORE

  4. 3. Robust Registration of ToF and RGB-D Camera Point Clouds

    University essay from KTH/Fastigheter och byggande

    Author : Shuo Chen; [2021]
    Keywords : Robustness; Estimator; Feature extraction; RANSAC; BLAVE; M-estimator; ToF; RGB-D; Robusthet; Uppskattare; Särdragsextraktion; RANSAC; BLAVE; M-uppskattare; ToF; RGB-D;

    Abstract : This thesis presents a comparison of M-estimator, BLAVE, and RANSAC method in point clouds registration. The comparison is performed empirically by applying all the estimators on a simulated data added with noise plus gross errors, ToF data and RGB-D data. The RANSAC method is the fastest and most robust estimator from the comparison. READ MORE

  5. 4. Quality Assessment of OpenStreetMap Footpath Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexander Hjelm; [2020]
    Keywords : ;

    Abstract : This project assesses the feasibility of reconstructing virtual cities from OpenStreetMap (OSM) road and building data, and will focus on the feasibility of including pedestrian footpaths. It will be examined how common it is that footpaths overlap with other map features such as roads and buildings. READ MORE

  6. 5. Automatic Room-Blueprint Extraction using SfM

    University essay from Lunds universitet/Matematik LTH

    Author : Joakim Ericson; Filip Jardby; [2020]
    Keywords : Technology and Engineering;

    Abstract : In this thesis the possibility of automatically generating a blueprint of an indoor area, for example a grocery store, using a smartphone camera and images from existing analytic or surveillance cameras was examined. The method used for the transition between 2D camera images and 3D reconstruction was Structure from Motion. READ MORE
