Image encryption plays a major role in information security. It is mainly used to convert the original image into another form. In this work, we propose a bit plane slicing of digital image to provide the more security. The main aim of BPS is used to divide the digital image into 8 bit planes. The bit plane is further rotated in order to provide better encrypted image and to make hacking more difficult. It focuses on two techniques such as bit plane slicing and image rotation for efficient image encryption. The classification of bit plane is used for analyzing the importance played by each bit of an image. It is used to estimate the each pixel of an image. The proposed technique involves rotation of bit planes is employed to make highly secure image encryption. By this method scrambling of an image is based on efficient technique even it is intercepted, the information cannot be understood. It is mainly useful for image compression because it exhibits high coding efficiency. This method which makes the decryption of an image more difficult compared to other techniques.Keywords

Medical imaging systems have advanced in a dynamic progress. There have been substantial improvements in characteristics such as sensitivity, resolution, and acquisition speed. The interactive tools allowed us to perform image transformations, edge detection and noise removal, region-of-interest processing, filtering, basic statistics, curve fitting, FFT, DCT and Random Transform. Making graphics objects semitransparent is a useful technique in 3-D visualization which furnishes more information about spatial relationships of different structures. The toolbox functions implemented in the open MATLAB language has also been used to develop the customized algorithms.Keywords

Computer hallucination, unlike humans, still has not fully acquired the facility to categories a person’s age group from an image of the person’s face. Successful gender and age classification could be used to boot the performance of face recognition system. Fuzzy models have been used and analyzed in this work to achieve the desired results. The concept of fuzzy lattice neural model is introduced and is applied to classify the age group of a person from the gray scale facial image. Next the fuzzy lattice relation model is constructed and is used to classify the age group of a person. Then the fuzzy lattice neural model is applied to segment an aerial gray scale image.

Image encryption is used to protect the data of an image in the most secure way. In this paper, we perform encryption and decryption of the three color planes based on gray code effect and fast Fourier transform. Gray level codes indicate that occurrence of one bit changes from a previous state of current. This process allows the system to detect the error when more than one bit changes occur. It is more efficient than binary bit plane decomposition. The Fourier transform is mainly used to represent the frequency characteristic of a spatial domain image. The color plane scrambling process is done by combining three individual encrypted planes into one composite image. This method which is applicable for any type of image formats as bmp, JPEG, GIF. This paper gives a simple way to scramble the image in unpredictable way. It provides more security than other encryption algorithm. The original images can be retrieved using a correct security key which achieves better results than the other existing methods. By exploiting gray code and Fourier transforms it increases the difficulty of decoding.Keywords

For querying large amounts of moving objects, a key problem is to create efficient indexing structures that make it possible to effectively answer various types of queries. Traditional spatial indexing approaches cannot be used because the locations of moving objects are highly dynamic, which go ahead to frequent updates of index structures, which in turn will cause huge expenditure. In earlier researches states that the functional approaches to manage moving objects in Euclidean spaces. In this paper, to describe the techniques that effectively indexing the positions of moving objects in spatial networks and supports the heavy update loads. Not only that and also increases the efficiency of the query extraction. The performance study, comparing this indexing method with FNR-Tree, MON-Tree, and TPR-Tree, shows that ANR-Tree outperforms them.
