提出了一种具有完全重构的二维零相位有限冲击响应 ( FIR)菱形子带滤波器组的设计方法 ,该方法采用变量代换并通过调整窗函数的参数和传递函数来改变频率特性 ,能方便、灵活地控制频率特性 .设计实例表明 ,所设计的滤波器频率特性较好 ,用设计的滤波器对一真彩色内窥镜图像进行处理 ,达到了满意的效果 A completely reconstructed design method of two-dimensional zero-phase finite impulse response (FIR) rhombic subband filter bank is proposed. The method uses variable substitution and alters the frequency characteristics by adjusting the parameters and transfer functions of the window function, Can easily and flexibly control the frequency characteristics.The design example shows that the designed filter has better frequency characteristics and the designed filter is used to process a true color endoscope image to achieve satisfactory results
