Fast Discrete Curvelet Transforms This paper describes two digital implementations of a new mathematical transform, namely,  the second generation curvelet transform [12, 10] in two and three dimensions. The first digital transformation is based on unequally-spaced fast Fourier transforms (USFFT) while the second is based on the wrapping of specially selected Fourier samples    این مقاله 2 روش اجرایی دیجیتالی جدید وابسته ریاضیات، مشهور به (نسل دوم تغییر اشکال انحرافی) ] 10 و 1 .
