由于二维菱形滤波器组能够结合人的视觉特性分解信号，因而在子带编码中日益受到人们的重视，有关二维菱形滤波器组的设计和利用菱形滤波器组处理视频信号的报道也逐渐增多．利用切比雪夫优化法设计的零相位菱形滤波器组不仅具有较小的重建误差，而且滤波器本身的性能也可以得到控制．由于该方法利用一维切比雪夫优化和ＭｃＣｌｅｌｌａｎ变换，再加上所设计的滤波器为正交镜像的，因而设计简单。通过实验证明，利用该方法设计的滤波器的性能较为理想。
Due to the fact that two-dimensional rhomboid filters can decompose signals in combination with human visual characteristics, people pay more and more attention to the sub-band coding. The design of two-dimensional rhomboid filters and the processing of video signals by diamond filters also gradually increase. The zero-phase diamond filter bank designed by the Chebyshev optimization method not only has less reconstruction error, but also the performance of the filter itself can be controlled. Because this method makes use of one-dimensional Chebyshev optimization and McClellan transformation, coupled with the design of filters for orthographic mirroring, the design is simple. Experiments show that the performance of the filter designed by this method is better.
