  1. 11. Face detection for selective polygon reduction of humanoid meshes

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Johan Henriksson; [2015]
    Keywords : mesh; reduction; decimation;

    Abstract : Automatic mesh optimization algorithms suffer from the problem that humans are not uniformly sensitive to changes on different parts of the body. This is a problem because when a mesh optimization algorithm typically measures errors caused by triangle reductions, the errors are strictly geometrical, and an error of a certain magnitude on the thigh of a 3D model will be perceived by a human as less of an error than one of equal geometrical significance introduced on the face.

  3. 12. Optimal Coherent Reconstruction of Unstructured Mesh Sequences with Evolving Topology

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Christopher Birger; [2014]
    Keywords : Mesh registration; Surface Tracking; Coherent Reconstruction;

    Abstract : This thesis work will investigate and implement a method for reconstructing an unstructured mesh sequence with evolving topology. The goal of the method is to increase frame-to-frame coherency of the triangulation. READ MORE

  4. 13. FFT Hardware Architectures with Reduced Twiddle Factor Sets

    University essay from Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska högskolan

    Author : Rikard Andersson; [2013]
    Keywords : FFT; SDF;

    Abstract : The goal of this thesis has been to reduce the hardware cost of SDF FFTs. Inorder to achieve this, two methods for simplifying rotations in FFTs are presented:Decimation and Reduction. When applied, these methods reduce the total amountof angles that the rotators need to rotate, as well as the total angle count of theFFT. READ MORE

  5. 14. Automatic Mesh Repair

    University essay from Informationskodning

    Author : Agnes Larsson; [2013]
    Keywords : Automatic mesh repair; Manifold dual contouring; Jacobi rotations; Octree;

    Abstract : To handle broken 3D models can be a very time consuming problem. Several methods aiming for automatic mesh repair have been presented in the recent years. This thesis gives an extensive evaluation of automatic mesh repair algorithms, presents a mesh repair pipeline and describes an implemented automatic mesh repair algorithm. READ MORE

  6. 15. Implementation of 64-point FFTs as a building block for OFDM-based standards with respect to different criteria

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sarojanarayanamurthy Rajavari Krishnaih Lokanadhan; [2013]
    Keywords : ;

    Abstract : Abstract This master thesis implements a critical block: Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT) for standards using Orthogonal Frequency Division Multiplexing (OFDM). They are used in OFDM systems for modulating / demodulating subcarriers. READ MORE
