    • Two-Dimensional Textural Edge Detection Using Ω-Gaussian Filter 

      Park, Jinwoo; Poon, Ting-Chung; Indebetouw, Gary (Optical Society of America, 1986-11-01)
      A textural edge detection frequency domain filter is proposed to locate the boundary between two textural domains modulated by different spatial frequencies. This filter is derived from a zero-order prolate spheroidal ...
