  • Hung, T; Hoang, Tuan; Nguyen, Tuan (IEEE, 2007)
    A new design for linear phase diamond-shaped (DS) and circular-shaped (CS) 2-D filters is developed. First, the frequency masks are efficiently constrained by 2-D second-order trigonometric polynomials. Then semi-definite ...
  • Hung, T; Hoang, Tuan; Nguyen, Tuan (IEEE, 2007)
    A new design method for linear phase half-band diamond (DS) and fan-shaped (FS) 2-D filters is proposed. A general formulation for frequency mask constraints in different shapes using 2-D trigonometric curves is developed. ...
  • Hung, T; Hoang, Tuan; Vo, Ba-Ngu; Nguyen, Tuan (IEEE, 2006)
    In this paper, a new technique for designing linear phase 2-D filter based on semi-definite programming (SDP) is proposed. This approach allows the design of 2-D filters with accurate cut-off frequency, subject to hard ...
