Modified LSB Based Steganography and Noise Removal for Noisy Image

Abstract

A when an image is processed for visual interpretation, the viewer is the ultimate judge of how well a particular method works. Visual evaluation of image quality is a highly subjective process. The main purpose of combine the feature of two fields Image enhancement and Steganography because we add salt and pepper noise in the original image and then secret image is embedded in the noisy image, produce a noisy stego image ,the message is extracted from the noisy stego image and finally removing the noise from stego image by various filters. In this paper, we implemented the various median filter such as Fuzzy based, Decision based and conventional median filters used for noise removal especially for salt and peppers noise. We also implemented the steganography based on LSB.
