Linear filtering techniques have serious limitations in dealing with signals that have been
created or processed by a system exhibiting some degree of nonlinearity, or, in general …

Rational filters are extended to multichannel signal processing and applied to image
interpolation. Two commonly used decimation schemes are considered: a rectangular grid …

A new class of nonlinear filters is introduced, called median-rational hybrid filters (MRHFs),
based on rational functions (RFs). The output is the result of rational operation taking into …

A study on the use of vector rational interpolation for the estimation of erroneously received
motion fields of an MPEG-2 coded video bitstream has been performed. Four different …

In this paper, we present an unsharp masking-based approach for noise smoothing and
edge enhancing in multichannel images. The proposed structure is similar to the …

A study on the use of vector rational interpolation for the estimation of erroneously received
motion fields of MPEG-2 predictively coded frames is undertaken in this paper, aiming …

Linear filtering techniques have serious limitations in dealing with signals that have been
created or processed by a system exhibiting some degree of nonlinearity or, in general …

In this paper, we present an unsharp masking-based approach for noise smoothing and
edge enhancing. And apply it to color image processing. The proposed structure is similar to …

Integrating machine vision in industrial automation involves providing computers typically of
human vision. Vision" engines" are increasing in advances in processors like Digital Signal …

本文首先阐述了基于统计特征的图像插值方法, 该方法通过提取待插入像素所在区域的协方差
矩阵和协方差向量, 得出适应于边缘位置和方向的插值权重. 为了把基于统计特征的图像插值 …
