An adaptive spatial filter for additive Gaussian and impulse noise reduction in video signals
نویسندگان
چکیده
This paper presents a new method for suppressing noise in video sequences. The filter is an extension of the sigma filter. It uses local measurements to obtain noise reduction while preserving the image edges and details. By using a special defined weighting function, this filter can reduce both Gaussian and impulse noise effectively.

متن کاملAdaptive Optimum Notch Filter for Periodic Noise Reduction in Digital Images
Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
متن کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
