In this paper, we aim to present a general introduction to steganography or data-hiding as it is sometimes just known. We then turn to data-hiding in images. When examining these data-hiding techniques, we bear in mind Benderâ„¢s specifications, such as degradation of the cover data must be kept to a minimum, and the hidden data must be made as immune as possible to possible attack from manipulation of the cover data.

Steganography in images has truly come of age with the invention of fast, powerful computers. Software is readily availab ....etc

ABSTRACT: The normal direction of the bone contour in computed tomography (CT) images provides important anatomical information and can guide segmentation algorithms. Since various bones in CT images have different sizes, and the intensity values of bone pixels are generally nonuniform and noisy, estimation of the normal direction using a single scale is not reliable. We propose a multiscale approach to estimate the normal direction of bone edges. The reliability of the estimation is calculated from the estimated results and, after re-scaling, ....etc

Computers are beginning to replace photographic archives as the preferred form of repository. Computer based images repositories provides a flexible that cannot be attained with collection of printed images. Recently there has been as explosion in the number of images available to computer users. As this number increases, users require more sophisticated methods of retrieval. The area of content-based image retrieval is a hybrid research area that requires knowledge of both computer vision and of database systems. Large image databases are bein ....etc

As we all know . if we want to search any stuff using a search engine, we always type the name even if we are searching for images. we first type its name and then use a image filter. This project is to develop some algorithm by which users give sample image (by uploading) to a search engine and the search engine will find best suitable image result.. ....etc

Automatic Segmentation of Digital Images Applied In Cardiac Medical Images
Abstract:
In this project, at the initial stage, the the segmentation is used to separate the image in parts that represents an interest object, that may be used in a specific study. There are several methods that intend to perform such task, but are difficult to find a method that can easily adapt to different type of images, that often are very complex or specific. To resolve this problem, this project aims to presents an adaptable segmentation method that ca ....etc

The word Steganography literally means ?covered writing? as derived from Greek. It encompasses all methods of secret communication that conceal the very existence of the message.

Digital technology gives us new ways to apply Steganographic techniques including one of the most intriguing that of hiding information in the digital images. A popular method is the LSB encoding, so encoding and detection of LSB Steganography is discussed in detail. Steganography goes well beyond simply embedding text in an image.

It also pertains to other media ....etc
