image processing. In general the results of the noise removal have a strong influence on the quality of the image processing technique. Several techniques for noise removal are well established in color image processing. The nature of the noise removal problem depends on the type of the noise corrupting the image. In the field of image noise reduction several linear and non linear filtering

Computational Statistics with Application to Bioinformatics

Abstract: A novel adaptive Wiener filter solution has been derived for digital image processing applications. It uses a local variance field of the distorted image, which permits one to bypass a priori knowledge about statistical properties of the original image.

1.1 Digital image processing Digital image processing is the technology of applying a number of computer algorithms to process digital images. The outcomes of this process can be either images or a set of representative characteristics or properties of the original images. The applications of digital image processing have been commonly found in robotics/intelligent systems, medical imaging
