Algoritma yang mudah dan cekap untuk poligon morphing dicadangkan dalam kertas ini. Kami mengguna pakai perwakilan lengkung parametrik berdasarkan anggaran parameter Fourier untuk memindahkan proses morphing tradisional dalam domain spatial kepada proses dalam ruang parametrik sebaliknya. Prinsipnya adalah untuk menyatakan poligon sebagai penyatuan segmen padanan yang diterangkan oleh parameter Fourier yang dianggarkan. Kami juga telah mereka bentuk kaedah pensampelan semula data yang mengawal perubahan bentuk secara berkesan mengikut nilai kelengkungan yang sepadan. Objek perantaraan di antara poligon sumber dan sasaran kemudiannya dibina berdasarkan interpolasi parameter Fourier bagi dua poligon. Parameter Fourier bagi poligon yang disampel semula boleh diperoleh dengan cekap dengan menggunakan algoritma transformasi Fourier pantas (FFT). Keputusan eksperimen menunjukkan bahawa penampilan objek morphed adalah lebih baik daripada yang diperolehi oleh kaedah yang ada.

Abstract: A simple and an efficient algorithm for polygon morphing is proposed in this paper. We adopt the parametric curve representation based on Fourier parameter estimation to transfer the traditional morphing process in spatial domain to a process in the parametric space instead. The principles are to express the polygon as the union of matching segments that are described by the estimated Fourier parameters. We have also designed a data resampling method that effectively controls the shape morphing according to the corresponding curvature values. Intermediate objects in-between the source and target polygons are then constructed based on the interpolation of Fourier parameters of the two polygons. Fourier parameters of the resampled polygons can be obtained efficiently by using the fast Fourier transform (FFT) algorithm. The experimental results show that the appearances of the morphed objects are superior to the ones obtained by the methods available.
