Image Restoration with Two-Dimensional Adaptive Filter Algorithms
Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...
متن کاملTwo dimensional adaptive filter using Laguerre function
In this paper, a new two dimensional (2D) adaptive filter structure is developed. It is based on modeling the impulse response of the 2D IIR systems as a finite linear combination of a set of 2D Laguerre orthonormal functions. When long impulse response system is required to identify, computer simulation shows that the 2D Laguerre filter has better performance than the conventional 2D FIR filte...
متن کاملTwo-dimensional general fan-type FIR digital filter design
Conventional transform methods can only design ordinary and quadrant fan-type filters with 90 ° pass-angle. In this paper, three efficient approaches are proposed for designing general arbitrary pass-angle fan-type filters. They include the analytic closed form, the rotated, and the frequency sampling design methods. Each approach has its features and is very suitable for directional filtering ...
متن کاملTwo dimensional IIR and FIR digital notch filter design
In this paper, the two dimensional (2D) digital notch filter design problem is investigated. First, we develop a simple algebraic method for 2D IIR notch filter design. This approach not only has closed-form transfer function but also satisfies bounded input bunded output ( ~ 1 ~ 0 ) stability condition. Next, we use Lagrange multiplier method to design 2D FIR notch filters. This design is opti...
