Adaptive Filtering Principle The adaptive filter is a digital filter that can perform digital signal processing based on the automatic adjustment of the input signal. Denoising is one of the important task and pre-processing step in digital image processing.there are many median filters are available for impulse noise reduction although these methods have been improved, but the quality of denoising image is still not satisfactory[1]. In this case, the same input feeds both the adaptive filter and the unknown. And, best of all, most of its cool features are free and easy to use. Advanced Digital Signal Processing ???????? Digital image processing focuses on two major tasks –Improvement of pictorial information for human interpretation –Processing of image data for storage, transmission and representation for autonomous machine perception Some argument about where image processing ends and fields such as image Adaptive filters are commonly used in image processing to enhance or restore data by removing noise without significantly blurring the structures in the image. optic axis is in the direction labelled z. In image noise removal, commonly used methods include a mean filter method, an adaptive Wiener filter method, a median filter, and a wavelet transform method.
