用于基于变换和反变换执行内插的方法和设备
Abstract:
提供了一种用于基于变换和反变换执行内插的方法和设备。所述方法包括：根据内插位置从多个不同的滤波器中选择用于在整数像素单元的像素值之间进行内插的第一滤波器；以及通过使用选择的第一滤波器，在整数像素单元的像素值之间进行内插来产生至少一个分数像素单元的至少一个像素值。
Abstract(English):

Provided are a method and apparatus for interpolating an image. The method includes: selecting a first filter, from among a plurality of different filters, for interpolating between pixel values of integer pixel units, according to an interpolation location; and generating at least one pixel value of at least one fractional pixel unit by interpolating between the pixel values of the integer pixel units by using the selected first filter.
