An Improved Image Steganography Technique using Modified Data Image
Abstract: The science of secret communication is known as steganography. Steganography hides the secret data from unauthorized user. Unlike cryptography, steganography hides the existence of secret information rather than hiding its meaning only. Many different file formats can be use as cover media but these days the digital image based steganography is most popular on internet and web. The capacity of hiding secret data is limited in steganography and it depends …

Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
Abstract: In this paper, system uses the cryptography and steganography concept, which proposes a lossless, reversible, and combined data hiding methods for images encrypted by public key cryptosystems with probabilistic and homomorphic properties. In the lossless method, pixels of encrypted images are replaced with new values to embed additional data into LSB-planes of ciphertext pixels by multiple layer wet paper coding. Thus, original data can be directly extracted from encrypted image, …

Texture Based Segmentation of Remotely Sensed Images
Abstract: Texture based segmentation approach extracts homogeneous regions that have similar texture properties. The texture patterns make use of the gray scale relationship between the center pixel and its surrounding neighbors. In this paper, a novel method is proposed that encodes the spatial relationship between adjacent pairs of neighbors on either side of the center pixel including itself along the given directions in an image. The novelty of the proposed method …
