  1. 1. The effect of the hyperparameters of an RBF SVM on classifying pneumonia

    University essay from KTH/Datavetenskap

    Author : Rikaz Nismi; Alfred Hoflin; [2022]
    Keywords : ;

    Abstract : Pneumonia is a deadly disease if gone untreated. In order to treat it, first it has to be discovered, which can be done by examining patterns of chest X-ray images. This process can be done by human experts but there is also a desire to make it more efficient by utilizing machine learning. READ MORE

  3. 2. Detection of Pests in Agriculture Using Machine Learning

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Emma Olsson; [2022]
    Keywords : machine learning; svm; sliding window; mask r-cnn; yolov5;

    Abstract : Pest inventory of a field is a way of knowing when the thresholds for pest controlis reached. It is of increasing interest to use machine learning to automate thisprocess, however, many challenges arise with detection of small insects both intraps and on plants. READ MORE

  4. 3. Histogram of Oriented Gradients in a Vision Transformer

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Jakob Malmsten; Heja Cengiz; David Lood; [2022]
    Keywords : vision transformer; vit; histogram of oriented gradients; hog; ai; machine learning; artificial intelligence; MNIST;

    Abstract : This study aims to modify Vision Transformer (ViT) to achieve higher accuracy. ViT is a model used in computer vision to, among other things, classify images. By applying ViT to the MNIST data set, an accuracy of approximately 98% is achieved. READ MORE

  5. 4. VISUAL DETECTION OF PERSONAL PROTECTIVE EQUIPMENT & SAFETY GEAR ON INDUSTRY WORKERS

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Fredrik Strand; Jonathan Karlsson; [2022]
    Keywords : Machine learning; yolo; yolov4; cnn; ppe; personal protective equipment; object detection; computer vision; deep learning; artificial intelligence; ai; real-time object detection; real-time; safety; construction; workers; industry; face recognition;

    Abstract : Workplace injuries are common in today's society due to a lack of adequately worn safety equipment. A system that only admits appropriately equipped personnel can be created to improve working conditions and worker safety. The goal is thus to develop a system that will improve construction workers' safety. READ MORE

  6. 5. Tracking Under Countermeasures Using Infrared Imagery

    University essay from Linköpings universitet/Datorseende

    Author : Sara Modorato; [2022]
    Keywords : computer vision; infrared imagery; tracking; countermeasures; discriminative correlation filters; Efficient Convolution Operator tracker; Spatial-Temporal Regularized Correlation Filter tracker; Visual Object Tracking; flare; DIRCM; multiple wavelength bands; features;

    Abstract : Object tracking can be done in numerous ways, where the goal is to track a target through all frames in a sequence. The ground truth bounding box is used to initialize the object tracking algorithm. Object tracking can be carried out on infrared imagery suitable for military applications to execute tracking even without illumination. READ MORE
