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 …

Review on CBIR Image Based on Colour, Texture and Shape Features of Biomedical Image Applications
Abstract: This study seeks to understand how different image enhancing methods affect the sensitivity of contrast-based textural measures and morphological traits derived from high-resolution satellite data (three-band SPOT-5). The built-up/non-built-up detection framework is the backbone of every biomedical application. Using supervised learning while working with a low-resolution reference layer reduces uncertainty and boosts the reference layer's quality in a roundabout way. The image's histogram is recalculated based on contrast in order …
