Optimization-based design of 2-D IIR filters using two approximation criteria

Czytaj za darmo! »

Two-dimensional (2-D) digital filters have many applications in fields such as image processing, sonar and radar signal processing, video signal filtering, and computational tomography. Therefore, the design of 2-D filters has been widely investigated in recent years. Both finite impulse response (FIR) and infinite impulse response (FIR) 2-D filters have been studied extensively. FIR filters[...]

Design of two-channel linear-phase FIR biorthogonal filter banks using multicriterion optimization

Czytaj za darmo! »

Filter banks have found important applications in many different areas such as speech coding, image processing, signal analysis, subband adaptive filtering, etc. [3-5, 9, 12, 14-17]. Filter banks decompose a signal into two or more adjacent frequency bands and reconstruct the signal by combining two or more signals into a single signal. Decomposition is performed in analysis filter banks and[...]
