Abstract

Images acquired through modern cameras may be contaminated by a variety of noise sources (e.g. photon or on chip electronic noise) and also by distortions such as shading or improper illumination. Therefore a preprocessing unit has to be incorporated before recognition to improve image quality. General-purpose image filters lacks the flexibility and adaptability for un-modeled noise types. The EHW architecture evolves filters without any apriori information. The approach chosen here is based on functional level evolution The proposed filter considers spatial domain approach and uses the overlapping window to remove the noise in the image.
