  1. 1. Instance segmentation using 2.5D data

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

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

    Sammanfattning : 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. LÄS MER

  3. 2. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

  4. 3. Visualisering av signaler från delay line detektor

    Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Abd Al Salam Abo Taha; Israa Ali; [2023]
    Nyckelord :Delay line detector; Python; Oscilloscope; Microchannel Plate; Artifacts; Trigger; Detector image; Anode; Synchrotron light; X-ray.; Technology and Engineering;

    Sammanfattning : MAX IV laboratoriet ger forskare möjlighet att analysera och studera material på atomnivå genom att använda högenergetiska ljusstrålar. Synkrotronljusanläggningen MAX IV genererar intensiva strålar av elektromagnetisk strålning, inklusive röntgenstrålning. LÄS MER

  5. 4. Structure from Motion with a Neural Network

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Jiarong Gong; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This project delves into the 3D reconstruction of both single and multiple rigid motions, examining the potential of deep learning methods, such as that proposed by Moran et al., to supplant traditional geometry-based approaches. The project is structured into two main parts. LÄS MER

  7. 5. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ashray Ugle; [2023]
    Nyckelord :Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

    Sammanfattning : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.
