摘要：
Linear filter theory based on Wiener filtering is well understood and used widely in many fields of image and signal processing In this work a Field-Programmable Gate Array (FPGA) implementation of a series of non-linear filters is developed based on the concepts of Volterra series and these are applied to image interpolation problems More explicitly, the aim is to interpolate one field of a frame of a television picture in real time to form an estimate, of the second field This is known as de-interlacing and is useful in many areas of video processing, for example standards conversion.
