"... Abstract: In this paper, a new tool that is fractional Fourier Transform is introduced to 3D model retrieval. And we propose a 3D model descriptor based on 3D factional Fourier transform. Fractional Fourier transform is a general format of Fourier transform, and add a variables that is order. Our ap ..."

"... Abstract. We consider the problem of quickly estimating the best kterm Fourier representation for a given frequencysparse bandlimited signal (i.e., function) f: [0,2π] → C. In essence, this requires the identification of k of the largest magnitude frequencies of ˆf ∈ C N, and the estimation thei ..."
