In this paper, a new image encryption scheme for colour BMP images using a secret key of 120-bits is proposed. Initially, image is divided into blocks subsequently into color components. Each color component is modified by performing bitwise operation which depends on secret key used in algorithm

using the cover object as an image. From this image, we have chosen two types: Gif and BMP. The comparison and is based on a number of criteria to find out the strengths and weaknesses when using any of the two types. Index Terms—About four key words or phrases in alphabetical order, separated by commas

Abstract—Steganography comes from the Greek words steganos, roughly translating to “covered writing”. Steganographic techniques allow one party to communicate information to another without a third party even knowing that the communication is occurring. The ways to deliver these “secret messages ” vary greatly. This paper explores several methods in detail, and attempts to test them out in code, and in practice, through several examples. “The goal of steganography is to hide messages inside other harmless messages in a way that does not allow any enemy to even detect that there is a second secret message present.” 1.

Abstract—With the rapid development of technology of multimedia, the traditional information retrieval techniques based on keywords are not sufficient, content- based image retrieval (CBIR) has been an active research topic. The large amount of image collections available from a variety of sources

Abstract- Thinning is a very important preprocessing step for the analysis and recognition of different types of images. Thinning is the process of minimizing the width of a line, in an image, from many pixels wide to just one pixel (Lam et al., 1992) [3]. Thus Correct and Reliable thinning

Abstract: Images of different formats are generated, edited and transmitted on a very regular basis in a vast number of systems today. The BMP format is the native format for the Windows World and vast majority of windows-based applications supports this format. But a BMP image is quite large

others for a given set of specific test images. A module was developed to generate these configurations. Index Terms—Image processing, image compression, region of interest, based scaling, SPIHT. complexity compared to the JPEG2000.

A new BMP image based steganography algorithm is proposed based on image intensity, added extended encryption algorithm and a more superior insertion technique of encrypted data bit to increase data insertion level in a BMP image. Image size, clarity, noise is also taken care of in this algorithm.

ABSTRACT: Angiogenesis and bone formation are tightly coupled during the formation of the skeleton. Bone morphogenetic protein (BMP) signaling is required for both bone development and angiogenesis. We recently identified endosome-associated FYVE-domain protein (endofin) as a Smad anchor for BMP re

The images for Figures 7 and 8 are incorrectly switched. The image that appears as Figure 7 should be Figure 8, and the image that appears as Figure 8 should be Figure 7. The figure legends appear in the correct order. The figures in their correct order can be viewed below.
