  1. 1. Using a Character-Based Language Model for Caption Generation

    University essay from Linköpings universitet/Interaktiva och kognitiva system

    Author : Simon Keisala; [2019]
    Keywords : Natural Language Processing; NLP; Machine Learning; ML; Neural Network; Caption Generation; Deep Learning; Recurrent Neural Network; Long-Short-Term-Memory; LSTM; word2vec; Language Model;

    Abstract : Using AI to automatically describe images is a challenging task. The aim of this study has been to compare the use of character-based language models with one of the current state-of-the-art token-based language models, im2txt, to generate image captions, with focus on morphological correctness.

  2. 2. Automatic Registration of Point Clouds Acquired by a Sweeping Single-Pixel TCSPC Lidar System

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

    Author : Mattias Mejerfalk; [2017]
    Keywords : point cloud; k-4pcs; tcspc;

    Abstract : This project investigates an image registration process, involving a method known as K-4PCS. This registration process was applied to a set of 16 long range lidar scans, acquired at different positions by a single pixel TCSPC (Time Correlated Single-Photon Counting) lidar system. READ MORE

  3. 3. Optimal Auxiliary Variable Assisted Two-Phase Sampling Designs.

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Henrik Imberg; [2016-06-22]
    Keywords : Anticipated variance; Auxiliary information in design; Maximum pseudolikelihood; Optimal designs; Poisson sampling; Two-phase sampling;

    Abstract : Two-phase sampling is a procedure in which sampling and data collection is conductedin two phases, aiming at achieving increased precision in estimation at reduced cost. The rst phase typically involves sampling a large number of elements and collecting data onvariables that are easy to measure. READ MORE

  4. 4. Software development of visualization tool for 3D

    University essay from Linköpings universitet/Institutionen för teknik och naturvetenskap

    Author : Martin Stenmarck; [2011]
    Keywords : 3D Graphics; software development; .Net; WPF;

    Abstract : The visualization is an important and vital tool of describing complex data for an uninitialized user. SICK has developed an array of advanced machine vision cameras all capable of producing large data sets of information at a high rate. READ MORE

  5. 5. Implementation and evaluation of content-aware video retargeting techniques

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Stefan Holmer; [2008]
    Keywords : seam carving; retargeting; aspect ratio; scaling; saliency; cut; shot; detection; widescreen; fullscreen; processing; optical flow; sampling; pan; scan; energy;

    Abstract : The purpose of this master thesis was to study different content-aware video retargeting techniques, concentrating on a generalization of seam carving for video. Focus have also been put on the possibility to combine different techniques to achieve better retargeting of both multi-shot video and single-shot video. READ MORE
