  1. 16. Push-up Tracking through Smartphone Sensors

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mårten Nilsson; Herman Wilén; [2016]
    Keywords : ;

    Abstract : Fitness tracking using machine learning algorithms is a new and widely unex-plored field. In most reports on fitness tracking, multiple accelerometers and other sensors are attached to the subject preforming exercises. This approach is not suitable for everyday usage. READ MORE

  3. 17. Robust Time Difference Estimation for Unknown Microphone Positions with Reverberation

    University essay from Lunds universitet/Matematik LTH

    Author : Simon Segerblom Rex; [2015]
    Keywords : TDOA; RANSAC; GCC-PHAT; GCC; time difference; range difference; sound tracking; Technology and Engineering; Mathematics and Statistics;

    Abstract : In this thesis a system is developed for robust time difference estimation for multiple microphones in reverberant environments, without any knowledge of the 3D positions of the microphones or the room. RANSAC is used to find line segments in sets of frames containing a number of the largest GCC-PHAT peaks. READ MORE

  4. 18. Micro-Expression Extraction For Lie Detection Using Eulerian Video (Motion and Color) Magnication

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Gautam Krishna Chavali; Sai Kumar N V Bhavaraju; Tushal Adusumilli; VenuGopal Puripanda; [2014]
    Keywords : Micro Expressions; Emotions; Eulerian Video Magnification; Histogram of Oriented Gradients; Voila-Jones Algorithm; Artificial Neural Networks; Support Vector Machines; Pattern Recognition and Classification; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Lie-detection has been an evergreen and evolving subject. Polygraph techniques have been the most popular and successful technique till date. The main drawback of the polygraph is that good results cannot be attained without maintaining a physical contact, of the subject under test. READ MORE

  5. 19. Clustering of Image Search Results to Support Historical Document Recognition

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : Javier Espinosa; [2014]
    Keywords : Historical documents; Computer vision; Features extraction; Clustering;

    Abstract : Context. Image searching in historical handwritten documents is a challenging problem in computer vision and pattern recognition. The amount of documents which have been digitalized is increasing each day, and the task to find occurrences of a selected sub-image in a collection of documents has special interest for historians and genealogist.

  6. 20. Detecting pedestrians intending to enter a crosswalk using a HMM tracker and a novel predictor

    University essay from Lunds universitet/Matematik LTH

    Author : Emanuel Hasselberg; [2013]
    Keywords : Mathematics and Statistics;

    Abstract : There is a demand for a more fluent and more efficient traffic. This can be achieved through more intelligent traffic light control. This thesis presents theory and an application in which people are tracked and their intentions to cross a crosswalk is predicted with a novel prediction algorithm based on Markov theory. READ MORE
