  1. 1. Normalized Convolution Network and Dataset Generation for Refining Stereo Disparity Maps

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Daniel Cranston; Filip Skarfelt; [2019]
    Nyckelord :Disparity Map; Disparity Refinement; Dataset Generation; Neural Network; Normalized Convolution;

    Sammanfattning : Finding disparity maps between stereo images is a well studied topic within computer vision. While both classical and machine learning approaches exist in the literature, they frequently struggle to correctly solve the disparity in regions with low texture, sharp edges or occlusions.

    Sammanfattning : Visual tracking is a computer vision problem where the task is to follow a targetthrough a video sequence. Tracking has many important real-world applications in several fields such as autonomous vehicles and robot-vision. LÄS MER

  4. 3. Evaluating Different Algorithms for Detecting Change-points in Time Series

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

    Författare :Henrik Eriksson; Victor Löfgren; [2018]
    Nyckelord :;

    Sammanfattning : Change-point detection is useful in many areas and there are several algorithms developed to cater specific needs such as fast calculations and statistical accuracy. In this report we outline five different algorithms, namely Fused Lasso, Filtered Fused Lasso, Normalized Fused Lasso, Dynamic Programming Approach and our own creation using convolution filtering, the Convolution Method.

  5. 4. Improved Temporal Resolution Using Parallel Imaging in Radial-Cartesian 3D functional MRI

    Master-uppsats, Datorseende

    Författare :Gustav Ahlman; [2011]
    Nyckelord :fMRI; PRESTO-CAN; SENSE; parallel imaging; temporal resolution; radial-Cartesian sampling; normalized convolution;

    Sammanfattning : MRI (Magnetic Resonance Imaging) is a medical imaging method that uses magnetic fields in order to retrieve images of the human body. This thesis revolves around a novel acquisition method of 3D fMRI (functional Magnetic Resonance Imaging) called PRESTO-CAN that uses a radial pattern in order to sample the (kx,kz)-plane of k-space (the frequency domain), and a Cartesian sample pattern in the ky-direction.
