  1. Algorithms for transform selection in multiple-transform video compression

    Cai, Xun, Ph. D. Massachusetts Institute of TechnologyMassachusetts Institute of Technology2012

    Selecting proper transforms for video compression has been based on the rate-distortion criterion. Transforms that appear reasonable are incorporated into a video coding system and their performance is evaluated. This approach is tedious when a large number of transforms are used. A quick approach …

  5. Acoustic Seabed and Target Classification using Fractional Fourier Transform and Time-Frequency Transform Techniques

    Barbu, Madalina

    … The technique is based on the Fractional Fourier Transform (FrFT), which is better suited for sonar applications because FrFT uses linear chirps as basis functions. In the first stage of the algorithm, FrFT requires finding the optimum order of the transform that can be estimated based on the …
