  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sara Muminovic; Christina Lindén; [2023]
    Nyckelord :Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Sammanfattning : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. LÄS MER

  3. 2. Learning features for extrinsic camera calibration of wide-angle cameras

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Albin Holmkvist; Max Björkander; [2023]
    Nyckelord :Computer vision; camera calibration; machine learning; artificial intelligence; wireframes;

    Sammanfattning : This thesis attempts to solve the problem of estimating the extrinsic camera parameters (pitch and roll) from a wide-angle view image. The first contributionis a data generation pipeline capable of producing wide-angle distorted images with rotation and line segment annotations. LÄS MER

  4. 3. Real Time Vehicle Detection for Intelligent Transportation Systems

    Magister-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Elda Shurdhaj; Ulehla Christián; [2023]
    Nyckelord :Unmanned aerial vehicles UAVs ; vehicle detection; CNN architecture; snow cover; NVD; Yolov5s; Yolov8s; Faster R-CNN; real-time processing; edge devices;

    Sammanfattning : This thesis aims to analyze how object detectors perform under winter weather conditions, specifically in areas with varying degrees of snow cover. The investigation will evaluate the effectiveness of commonly used object detection methods in identifying vehicles in snowy environments, including YOLO v8, Yolo v5, and Faster R-CNN. LÄS MER

  5. 4. Interpreting Mental Rotation Performance in Self-Described Aphantasia through Cognitive Penetrability

    Master-uppsats, Umeå universitet/Institutionen för psykologi

    Författare :Dániel Pénzes; [2023]
    Nyckelord :mental imagery debate; cognitive penetrability; aphantasia; VVIQ; OSIQ; mental rotation;

    Sammanfattning : Mental images are unique mental representations and the depictive view in the imagery debate states that mental images have similar spatial structures as their corresponding external object. The propositional view, however, contends that beliefs about the external world influence a mental image – also known as the cognitive penetrability theory –, therefore mental images cannot be described in visual terms.

  7. 5. A heuristic approach to screw pose detection

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

    Författare :Emil Ransed; [2022]
    Nyckelord :;

    Sammanfattning : Object detection using vision systems could generally be accomplished using machine learning or conventional computer vision techniques. This thesis implements and compares three methods to locate screws on a flat plane using conventional computer vision on regular non stereo images without any depth or range information. LÄS MER
